As a mechanic, i hope this is where it stops. Most customers do not need 12 gears nor do they know how to use it effectively. On top of that, the amount of standards is kinda getting out of hand. There are 3 different I-Spec systems now, 3 different free wheels, I've lost count of all the different bottom brackets there are, 10, 11 and 12 speed systems are sold concurrently and so on. And that's just Shimano. I'm all for innovation, but its getting to much as of late. It really reminds me of the late 90ier/ early 2000s when manufacturers released new and revolutionary designs every year. Shimano Airlines! Inverted shifting! Dual Control! Oversized Centerlock! Axle mounted derailleurs! Five years later you couldn't get any spare parts anymore and everything thankfully became standardized again. I hope 12-spd is the end for now, because it's getting harder and harder to keep up with all these changes on a daily basis, never mind keeping all the frequently needed parts in store. Again I'm happier with my 11-spd Setup than any previous setup and I'll probably get the 12-spd once it has been established, but the industry really needs time to let it customers breathe for a bit. But what annoys me the most about these step by step "innovations" is the way they pretend they have changed everything. The 10-spd rear derailleur is basically the same as the 11-spd and I'll bet its the same with the 12-Spd one as the XTR can be used with 11 or 12 spd. You can use a 11-Spd rear derailleur with 10 by systems and vice versa (depending on the cassette size you can't use older 10-Spd models) but they still sell them separately. Same with most front derailleurs, if anybody still uses those ;) Just admit you only changed the width of the chain and sprockets and streamline your product variety. Offer one XT rear derailleur for 12 to 10-Spd (assuming the 12-Spd still uses the 10 spd ratio, which is very likely) and be done with it. Shimano did it with 9-Spd before, why not own up to it and do it again. Also FYI 9-Spd MTB rear derailleurs are basically the same a 10-Spd rear derailleurs for road bikes. Shimano has been doing this for years now and it's kinda annoying, that you have to stock multiple products, that are mostly redundant because they refuse to admit they are compatible.
Just looks like they’ve just redesigned / reconfigured the old m8000 stuff and haven’t really improved the build quality. It still looks cheap and poorly built compared to SRAM’s stuff with cheap rattly plastic thumb shifters and the new brakes look exactly the same as my m8000 just with an extra clamp for lever flex. No mention of doing anything about the random bite point issues or what they’ve done to sort that. I’m keen to give it a try but I’ve been so disappointed with anything shimano I’ve bought over the last three or four years that I’m reluctant to give them any more money especially after being so impressed with SRAM’s gear since moving over. I’ll sit it out for a while see who ends up with the better product and see how well it holds up on my friends bikes.
After I saw the news of the new XTR M9100 I was eagerly waiting for the XT release. Super stoked. However, I am probably not going to upgrade from my M8000 setup: it is just too much hassle for this kind of improvement. Also, I am pretty sold on SRAM's AXS system. I hope Shimano is going to roll out something similar: wireless, reliable and dependable on.
JogBird they’re still going to come with NX at best your going to get a £4000 bike with slx. They’re never going to go back to putting xtr / x01 on reasonably priced bike. They’re just going to carry on chipping away charging more for less every year.
TheNotoriousMIC Luckily the lower end groups are getting really good. SLX even has quad piston brakes now. You aren’t really dropping features when going down the line of group sets, it’s mostly weight.
I have dt 350 and sram xx1 eagle, I don’t see any reason to switch to shimano, although I can buy a microspline freehub body. for too long they invented their 12 speed, time is already lost.
Cup and cone means that if the inner race wears out or pits (as it did with my old shimano hub) there's no way to replace it without replacing the whole hub. I'd rather go with an Onyx rear hub for durability, instant engagement and true silence.
Can you do a brake test.? Like stopping power from control speed? A proper brake test and not "trail" brake test. It would be good to see. I haven't seen any videos of actual brake comparison. Test it like how journalists test car brakes. Controlled test. Cheers
For a single braking run they will all stop you just fine providing they are set up and installed correctly. The limiting factor is your tyres, and potentially suspension depending on the terrain. There are benefits to more expensive brakes (more adjustable, better feel, easier maintenance, less fade etc), but the technology is mature enough that even entry level hydraulic brakes should be able to lock up on most surfaces. If you do need more power, getting bigger rotors is generally a good option, and can have a bigger effect on stopping power than upgrading the brakes themselves.
It's all in the tires ,suspension aaand brake feel and modulation. All brakes can lock the wheel ,but with some it's easier to control than with others . I love my slx m675s , love friends 4 pot zees even more, people say sram has better modulation , but I found most sram brakes have a "click" where they engage strongly , maybe I'm retarded but shimanos seem easier to control to me ...
hobmarg unless you’ve tried them, stop hating. My bike with the very parts you mentioned has been running problem free for 6 months. Plus, it’s cheaper.
@@henryfreund_ I have. NX Eagle cassette is ridiculously heavy to the point you can actually feel the impact on rear wheel acceleration and suspension performance. GX Eagle is acceptable for the price (but still $$) however chainline and cable tension is finnicky. Guide brakes, especially Guide R and RS issues are well documented. Codes are OK but Guides are trash compared to XT especially for the price. The only reason SRAM is so prevalent is because of their OEM build kit packaging that includes RockShox suspension and the also terribad Reverb dropper. It's easy and cost efficient for product managers for bike companies to spec all SRAM/RockShox so they do even when Shimano (and arguably Fox) are superior price/performance products.
We really need more competition in the MTB community. The level of conflict between SRAM and Shimano is absolutely absurd. I'll never buy a pre-configured bike again. Always - ALWAYS - frame alone and hopefully a reliable third party parts/drivetrain competitor.
I have the same groupset on my Merida Big Nine. I currently have 9,000km (around 5,600 miles) and it's still going strong. By the way, I mostly ride on paved and very minimal trails.
Currently still vaporware. A few shops around here got full groupset boxes, but only 1 per shop, gone straight away. Not stock of individual parts available yet.
Cup and cone bearings is a trash! Only shitty fishing company Shimano makes high range hub with them. All decent manufacturers like DT Swiss or Hope produce their top gorgeous hubs with decent sealed cartridge bearings.
usual sponsored mechanic bullshit trotted out about how wonderful cup and cone are - yes if you have nothing to do all day except shoot a couple of videos and maintain your bikes but a pain in the butt for the general public. I would say it was because he has to follow the shimano marketing bollocks for this video but he regularly trots out crap like this - Henry is a much more real world mechanic thinking about people who actually buy and own this stuff rather than living in the rarefied world where everything is a marketing 'test' freebie and you can move on before you actually wear the stuff out
Both cup and cone and sealed cartridge have their benefits. If a cup and cone system is taken care of properly it can last a very long time. There are cup and cone hubs still running on bikes from over 100 years ago. Sealed cartridge bearings are also good as they can be easily replaced and or upgraded from the factory specification, however you can only do this so many times before the hub shell and or axle has been compromised.
@@gmbntech why spend time and money on taking care of cup and cones while you can use sealed cartridge bearings without any tinkering and fuss? I had hubs with cartridge beatings which I used 20 000 + kilometres without any service or care. Sold to a new owner and now have a new bike with DT Swiss 240s and I'm sure they will last much more than 20 000 kilometres and I don't have to bother about any service and fixing, I will ride and shred not "take care of hubs" or spend time and money on fixing.
A way to run this group without the microspline would be to get an XD driver wheel and put on an e-thirteen cassette. It will cost more than the XT cassette though.
They make chains thinner and say that it's better because it's lighter. The reason why they actually make it thinner is because it's more likely going to snap so the consumer has to buy another chain, making Shimano more money.
They actually have to make the chains that way so they can space and fit the 12 gears properly for smooth engagement. More gears with less space in between equals thinner diameter chain. Unfortunately thinner means less durable but thats the tradeoff for more gears.
SLX have the same chainrings for the crank like XT :) Both weight the same 135grams for 34 T SM-CRM 75/85 are the same (but another alumiunim spider color). The tooth are made from steel. XTR is full alu construction!
@@jochem1986 It is cheap motorcycle and bicycle is cheap end of carbon HTs with some upgrades, but atm i dont even know why im bothering with bicycles anymore, i could get a new motorcycle for price of mid-top end AL framed FS bike or decent ebike.
Hi! Thank you so much for presenting the M8100 XT lineup! Can you specify the various models and differences? Ex. Dérailleurs has M8100, M8120 and what about SGS?
At around 5:15 you state that hyperglide+ now allows powering through when upshifting. But according to what I've read, it's exactly the opposite, as this was already the case with hyperglide. It's the plus version that now allows you to do the same when downshifting (from small to big cog). Correct me if I'm wrong, but it sounds more logical, as it seems to be the more difficult technical feat to achieve.
I just put togheter a mix groupset with xt m8100 shifter and breaking levers with shimanos Dropper post lever, i spec ev, xt 10-51 cassette, xtr m9100 det and xtrm9100 chain, my race face sixC cranks with The race face shimano 12s specifik chainring and my xt brake levers paired with my saint calipers, 203 rotors front and back. I love power under load, shifting is superior to Sram, its so fast, what can i say, its The best drivetrain ive been on, coming from XX1, XO1 12s. Shimano took their time but did their homework, worth The wait and did something Sram never Will be able to do, a set and forget, powerfull and reliable drivetrain
@@wonderwatch2239 exactly! Its so sharp and Nice looking AND its such a damn good system, i also like The fact that you get optislick inner cable and outer sp41 housing with The shifter and rear der and Dropper lever When you buy Sram you have to buy it seperatly and I agree, Srams gold cassette, gold chain, oil slick cassette and chain.. Seriously its just to much.. But they need The bling cuz ppl just see bling and not function :)
I've had nothing but problems with the new shimano 12spd. 2 failed xt freehub mechanisms that started creaking, then locked on and turned into fixed gear hubs. That was terrifying! Then the mail pivot of my slx rear mech corroded and the pulley cage no longer moved. Also, 3 xt 12spd shifters fail on me. On all three, one on the small springs that drives the shifts to easier gear/bigger cog breaks, then they can only shift to harder gears. Shimano has warrantied every I have listed, no questions asked. I do ride way more than most(endurance mtb racing is my thing) but this has been shocking to me, have had 11spd xt everything for years with zero issues. Think in the next year or two we'll start seeing massive recalls on all the 12spd parts as the average riders catch up with the mileage I put on my stuff.
Silent freehubs? Heresy! Interested in those brakes. Will have to see how the price will settle in. Which piston combo you recomend for general trail riding?
You say the one-by XT cranks come in 52mm, 55mm & 56.5mm chain lines. I thought 52mm was the Boost chain line. If so, what are the other two? One of them is super boost but then what is the third?
agreed , its implying that the other 5 or so group sets below XT are poverty spec junk. The smart money is on SLX anyway - 90% of the features & performance of XT but at 50 - 60 % of the cost of XT...........
They would have my money if it were not for the fact that they created this entire groupset on a proprietary hub. Guess Ill just save my money and buy more Jeep parts
I know this video is a year old, but if you Google its hard to find an answer, I have a cannondale cujo, it is 2×9. What would be involved in making it 1×12?
Not gonna lie, cup and cone hubs on an off-road bike sounds like a nightmare. I understand there are pros and cons to both systems, but an unsealed hub and dirt riding just would not mix well imo.
So is the shifting magic in the cassette? I'm really wanting to stick with SRAM shifters and derailleur but could I improve my loaded shifting by switching to a shimano cassette?
Hi, Is the Deore XT crankset (and presumably all of the other Shimano cranksets including the standard Deore) compatible with the Sram GXP Team Cups English 68/73mm bottom bracket? I have a feeling GXP won’t work with the Shimano cranks... Thanks.
Hi GMBN...I just went to the SLX 1x11...Using a Crank Brothers Cobalt 3 wheel and hub...The spline for the SLX fits...is there a difference in in the M8100 micro spline? Or would the M8100 fit if my SLX cassette fit?
When fitting a 1x M9100 XTR chainring to a 1x M8100 XT or M7100 SLX crankarm, which chainring lockring nut should be used? According to Shimano documents, the XTR crankset uses a different lockring than the XT/SLX. Is this specific to variances in the crankarms or the chainring? XTR lockring part number Y1X098050 XT/SLX lockring part number Y0J698060 The XTR lockring is specified as being compatible with the XT/SLX components, yet it specifically states in the manual (and on the lockring itself) that the XT/SLX lock ring included with the XT crankarm is "XT/SLX ONLY"... XT/SLX crankarm only or XT/SLX chainring only? Do I need an XTR lockring to run an XTR chainring on an XT crank?
Question to GMBN Tech, my MTB currently is using a Shimano XT M8000 11 speed cassette + shifter/derailleur setup, if I wanted to upgrade to the XT M8100 12 speed setup, do I also need to change my rear hub?
@@ayyylma0 Nope, not looking to buy because they're new but because the Q-factor on the XT boost crank will actually fit my frame without hitting the chainstay. If you can find me an old 170mm crank with a 148mm Q-factor I'll happily buy 🙂
@@AlphaAce15 Can you post a link to a Malaysian shop that sells XT FC M-8120-1, 170mm 1x12 with 148mm Q-factor 55mm chain line? Would genuinely appreciate a link. Can't find any in Europe or US, no stock of that size until September.
@@markpalmer3071 I doubt that, because Shimano has limited third party licensing, which means no company is allowed to make that hub standard without actually working with Shimano.
Shadow Price yeah the cassette is the most important component. I’d be very surprised if a shimano stamped steel loose cassette is ever going to match a fully machined xo1 cassette though.
The XT is what I will upgrade to during winter. My current 2x11 XT will then we worn out anyway and I can then finally convert to the 1x12 set. @Doddy I do have a 142 mm through axle in the back. Is it correct to go for the lowest Q factor? My cranks are already 180 mm long ans I would like to stick to it. Maybe Q factor chainline etc. could be addressed in a video?
I'm all about XT - I'm just not happy about all this talk regarding propriety stuff and non-compatibility. I have zero tolerance for such tactics. That will only lead to building your own rig - just like PCs. We'll just need more competitors entering the market to have more choices.
Can i ask something....is this shimano 12speed chain...CAN BE REPLACE WITH THE KMC 12 SPEED CHAIN????if the kmc 12speed chain is available in the.market... thanks GMBN
Have been looking at this, but i'm just so fond of my sram. It just works. I don't get why shimano chose to go with the silver looking casette, it's so 2010 imo. (Compared to the dark grey / black sram casette)
#askgmbntech do you know if it's possible to swap out an older, traditional, Shimano free hub for one of these newer fancy-pants micro spline bodies? I really like the new 12 speed group set, but I don't want to go through the hassle of changing my wheel set.
@@JeffWagen no, but there are ways and ways to make an add for a company. I don't have a problem with them making adds and having sponsors but I think they should be more clear about the difference between a review and a sponsored look at equipment...
@@Al_Gepe I agree, but unfortunately GMBN doesn't make reviews, they just show the products they are paid for, I generally look for other small channels to get a "rider" point of view as well as long term test, none of the big chanels does it unbiased, Wich is really bad.
I went with the full groupset and the hub is terrible. Sounds like 3 completely different hubs depending on the terrain/speed. Ranges from ridiculously loud to quiet and everything in between but never consistent. The constantly changing pitch takes your attention off of the trail. Took it back multiple times, had it replaced with no improvement....Eventually I was told ‘officially’ that Shimano realizes it has noise issues but it doesn’t affect the performance of the hub. Has anyone else experienced this problem?
No issues with assembly for me ua-cam.com/users/postUgkxHL1v1R3NE5x4KiYfyt8dnQmyNYz7qi5L but I could see where some might benefit from using an experienced bike assembler/mechanic. I'm an older rider starting back after a 10 year break. This bike exceeds my capabilities and has been easy to get comfortable riding. I'm mostly on easy trails with almost no street riding and have not been disappointed with the performance of the bike. My fitness level is far below what I previously rode with and because of that the mileage is going on the bike slowly. While I'm losing weight slowly, the bike seems to tolerate my 220 pounds just fine. The bike has been used by several family members ranging from 5'5" - 5'9".

@@jochem1986 It is cheap motorcycle and bicycle is cheap end of carbon HTs with some upgrades, but atm i dont even know why im bothering with bicycles anymore, i could get a new motorcycle for price of mid-top end AL framed FS bike or decent ebike.
Hi!
Thank you so much for presenting the M8100 XT lineup! Can you specify the various models and differences?
Ex. Dérailleurs has M8100, M8120 and what about SGS?
So informative, thank you!
I love this groupset. Is my future
im staying with my 2x11 best gear design yet.🙌
1x11 ;)
no no..i like to take my time .need the granny gear..🎅
Now I have idea for my tuner bike perfect for enduro downhill
Great explain
At around 5:15 you state that hyperglide+ now allows powering through when upshifting. But according to what I've read, it's exactly the opposite, as this was already the case with hyperglide. It's the plus version that now allows you to do the same when downshifting (from small to big cog).
Correct me if I'm wrong, but it sounds more logical, as it seems to be the more difficult technical feat to achieve.
I just put togheter a mix groupset with xt m8100 shifter and breaking levers with shimanos Dropper post lever, i spec ev, xt 10-51 cassette, xtr m9100 det and xtrm9100 chain, my race face sixC cranks with The race face shimano 12s specifik chainring and my xt brake levers paired with my saint calipers, 203 rotors front and back.
I love power under load, shifting is superior to Sram, its so fast, what can i say, its The best drivetrain ive been on, coming from XX1, XO1 12s. Shimano took their time but did their homework, worth The wait and did something Sram never Will be able to do, a set and forget, powerfull and reliable drivetrain
Gustav Bergström love my complete XTR 9100 as well, so reliable... and stelth looking, not the unicorn/pimp looking xx1
@@wonderwatch2239 exactly! Its so sharp and Nice looking AND its such a damn good system, i also like The fact that you get optislick inner cable and outer sp41 housing with The shifter and rear der and Dropper lever When you buy Sram you have to buy it seperatly and I agree, Srams gold cassette, gold chain, oil slick cassette and chain.. Seriously its just to much.. But they need The bling cuz ppl just see bling and not function :)
High doddy
I really wanna get this but
Micro spline
Just add the hub in with your groupset.
I've had nothing but problems with the new shimano 12spd. 2 failed xt freehub mechanisms that started creaking, then locked on and turned into fixed gear hubs. That was terrifying! Then the mail pivot of my slx rear mech corroded and the pulley cage no longer moved. Also, 3 xt 12spd shifters fail on me. On all three, one on the small springs that drives the shifts to easier gear/bigger cog breaks, then they can only shift to harder gears. Shimano has warrantied every I have listed, no questions asked. I do ride way more than most(endurance mtb racing is my thing) but this has been shocking to me, have had 11spd xt everything for years with zero issues. Think in the next year or two we'll start seeing massive recalls on all the 12spd parts as the average riders catch up with the mileage I put on my stuff.
I changed my mtb drive train from shimano xt to sram gx eagle this spring
I feel much better to ride.
Sorry, I will never go back to shimano.
I'm curious to see if I can use that shift lever for my lockout like you mentioned
Silent freehubs? Heresy!
Interested in those brakes. Will have to see how the price will settle in. Which piston combo you recomend for general trail riding?
4 pistons, looks cooler and you can never have enough stopping power on a trail bike
Now hope make a compatible freehub I looking at upgrade from 10 to 12 speed
but when will it actually be available in the US
Shimano and Strong aren't two words I've ever seen put together before, and I doubt I ever will
Very good
Nice rundown! Do you know if the derailleur should be used with direct mount hangers or standard hangers?
You say the one-by XT cranks come in 52mm, 55mm & 56.5mm chain lines. I thought 52mm was the Boost chain line. If so, what are the other two? One of them is super boost but then what is the third?
Well done doddy youve been reading alot
OMG yes please on my next bike
I always thought that the basic Deore was the workhorse.
agreed , its implying that the other 5 or so group sets below XT are poverty spec junk. The smart money is on SLX anyway - 90% of the features & performance of XT but at 50 - 60 % of the cost of XT...........
Even in the old steel bike days I never felt the need to upgrade from Deore to Deore XT.
They would have my money if it were not for the fact that they created this entire groupset on a proprietary hub. Guess Ill just save my money and buy more Jeep parts
You mean this groupset is not compatible with - say DT Swiss 350 hub?
Ghosty Yup
Its annoying that the new brake levers aren't compatible with the old gear shifters :/ but other then that I like them
I know this video is a year old, but if you Google its hard to find an answer, I have a cannondale cujo, it is 2×9.
What would be involved in making it 1×12?
Not gonna lie, cup and cone hubs on an off-road bike sounds like a nightmare. I understand there are pros and cons to both systems, but an unsealed hub and dirt riding just would not mix well imo.
Cup and cone bearings can be, and in this case certainly are, sealed.
Shimano prohibited German retailers to ship their products to Russia, prices here are DOUBLE. So no, no Shimano for me no more. Sram is just fine.
So is the shifting magic in the cassette? I'm really wanting to stick with SRAM shifters and derailleur but could I improve my loaded shifting by switching to a shimano cassette?
The microspline hubs not being available is a huge issue with this. They shot themselves in the foot with that.
Looks like they've ditched the Shadow Plus dropout fixing on the rear mech then?
I wish i was an adult and rich like you so i could buy cool groupsets
Great video!! I am currently planning for an upgrade, would it be possible to use the new xt crankset with an 11 speed cassette?
do a vid on upgrading from 11 to 12 spd please
Hi,
Is the Deore XT crankset (and presumably all of the other Shimano cranksets including the standard Deore) compatible with the Sram GXP Team Cups English 68/73mm bottom bracket?
I have a feeling GXP won’t work with the Shimano cranks... Thanks.
Hi GMBN...I just went to the SLX 1x11...Using a Crank Brothers Cobalt 3 wheel and hub...The spline for the SLX fits...is there a difference in in the M8100 micro spline? Or would the M8100 fit if my SLX cassette fit?
When fitting a 1x M9100 XTR chainring to a 1x M8100 XT or M7100 SLX crankarm, which chainring lockring nut should be used?
According to Shimano documents, the XTR crankset uses a different lockring than the XT/SLX. Is this specific to variances in the crankarms or the chainring?
XTR lockring part number Y1X098050
XT/SLX lockring part number Y0J698060
The XTR lockring is specified as being compatible with the XT/SLX components, yet it specifically states in the manual (and on the lockring itself) that the XT/SLX lock ring included with the XT crankarm is "XT/SLX ONLY"... XT/SLX crankarm only or XT/SLX chainring only?
Do I need an XTR lockring to run an XTR chainring on an XT crank?
Question to GMBN Tech, my MTB currently is using a Shimano XT M8000 11 speed cassette + shifter/derailleur setup, if I wanted to upgrade to the XT M8100 12 speed setup, do I also need to change my rear hub?
Is it just me or are those brake discs really that ugly?
tbh, I like the looks of those discs...1000 people... 🙃🤘
Well I can agree on the point that previous generation Freeza rotors (SM-RT99) look sexier. This generations looks... just decent.
It's not just you, Hope, Magura and even Centerlines look way better.
Please please do a review on the 2x12 for us guy's who are not 1x fans .Thanks
Can I still use SX Eagle crankset 1x12 in combination with a upgrade to Schimano 1x12 shifter, derailleur, rear hub?
unfortunately it is nowhere in stock and noone knows when it is going to be available
peter alexander I’m after a pair of XT cranks, been told by a Madison rep they’ll be available in September, most likely end of.
Bike components industry is genuinely insane. People will buy anything just because it's 'new'.
Already available in Malaysia.
@@ayyylma0 Nope, not looking to buy because they're new but because the Q-factor on the XT boost crank will actually fit my frame without hitting the chainstay.
If you can find me an old 170mm crank with a 148mm Q-factor I'll happily buy 🙂
@@AlphaAce15 Can you post a link to a Malaysian shop that sells XT FC M-8120-1, 170mm 1x12 with 148mm Q-factor 55mm chain line? Would genuinely appreciate a link.
Can't find any in Europe or US, no stock of that size until September.
Some say m8120 is suitable to use for 1x45t setup, please advice
The brake lever is ispec-ev and the shifter is ispec-ii right? And It is compatible.
My two month old xt 12 speed cogs broke. The rivet broke on the 8th cog and bent the cog. Is this how soft the new xt's are?
Can you get the free hub separately or do you have to get the whole lot?
It's not compatible with ANY current designs.
Only on Dt swiss wheels but I'm sure that will change soon enough.
@@markpalmer3071 I doubt that, because Shimano has limited third party licensing, which means no company is allowed to make that hub standard without actually working with Shimano.
@@th_js yeah agree but they'll have to at some point, especially when they want it factory fit for trek, giant Norco etc
Too bad its another new free hub... , I'm stuck with XD right now.
Just get a eagle cassette
@@anttiharing Then I may aswell just stay with sram, half the benefits of shimano groupo are in casette.
Shadow Price yeah the cassette is the most important component. I’d be very surprised if a shimano stamped steel loose cassette is ever going to match a fully machined xo1 cassette though.
@@SaKuLification LoveMTB made a video of it and it seems to be working smoothly enough
hello
does the 4 pistons systems is only compatible with 200mm front and 180mm rear discs ?
The XT is what I will upgrade to during winter. My current 2x11 XT will then we worn out anyway and I can then finally convert to the 1x12 set.
@Doddy
I do have a 142 mm through axle in the back. Is it correct to go for the lowest Q factor? My cranks are already 180 mm long ans I would like to stick to it. Maybe Q factor chainline etc. could be addressed in a video?
I'm all about XT - I'm just not happy about all this talk regarding propriety stuff and non-compatibility. I have zero tolerance for such tactics. That will only lead to building your own rig - just like PCs. We'll just need more competitors entering the market to have more choices.
do the new brake levers work with older bar clamp shifters? or do the clamps interfere?
Can i ask something....is this shimano 12speed chain...CAN BE REPLACE WITH THE KMC 12 SPEED CHAIN????if the kmc 12speed chain is available in the.market... thanks GMBN
hi sir, I just wantedt to ask 10-45t is it compatible for 11 speed 12x142 hub? I'm planning to buy the M8100 cassette 10-45t
Have been looking at this, but i'm just so fond of my sram. It just works.
I don't get why shimano chose to go with the silver looking casette, it's so 2010 imo. (Compared to the dark grey / black sram casette)
You're worried about the colour of your cassette? Spending time looking behind you and down between your legs while riding trail are you?
Cone bearings in the hubs?
Does this come with subtitles for those of us who are not geeks
Talk about Sram SX Eagle
my xt came with sealed cartridge bearings not the cup and cone
#askgmbntech do you know if it's possible to swap out an older, traditional, Shimano free hub for one of these newer fancy-pants micro spline bodies? I really like the new 12 speed group set, but I don't want to go through the hassle of changing my wheel set.
What about derailleaur Deore XT m8100 SG - medium cage?
Very big, long add for shimano
And what's the problem? Do you wake up in the morning and work for free? I don't think so, is their job, don't complain about it please.
@@JeffWagen no, but there are ways and ways to make an add for a company. I don't have a problem with them making adds and having sponsors but I think they should be more clear about the difference between a review and a sponsored look at equipment...
@@Al_Gepe I agree, but unfortunately GMBN doesn't make reviews, they just show the products they are paid for, I generally look for other small channels to get a "rider" point of view as well as long term test, none of the big chanels does it unbiased, Wich is really bad.
@@JeffWagen totally agree, it would really be great to have some unbiased opinion from such good presenters... Unfortunately... Denied!
Al Gepé it says paid promotion in the video on different occasions. 🤷♀️
So why doesn't the bolt on rotors have cooling fins?
Have i9 hubs don't want 2 switch 2 Moro spline or XD plus the adapter is $200
I went with the full groupset and the hub is terrible. Sounds like 3 completely different hubs depending on the terrain/speed. Ranges from ridiculously loud to quiet and everything in between but never consistent. The constantly changing pitch takes your attention off of the trail. Took it back multiple times, had it replaced with no improvement....Eventually I was told ‘officially’ that Shimano realizes it has noise issues but it doesn’t affect the performance of the hub. Has anyone else experienced this problem?
How do I unscrew the chainring? I'm having a hard time to do it. What tool should I use?
I just got new bike with Shimano SLX rear hub and it’s reeeally quite, almost silent on speed. Is it supposed to be so?
No issues with assembly for me ua-cam.com/users/postUgkxHL1v1R3NE5x4KiYfyt8dnQmyNYz7qi5L but I could see where some might benefit from using an experienced bike assembler/mechanic. I'm an older rider starting back after a 10 year break. This bike exceeds my capabilities and has been easy to get comfortable riding. I'm mostly on easy trails with almost no street riding and have not been disappointed with the performance of the bike. My fitness level is far below what I previously rode with and because of that the mileage is going on the bike slowly. While I'm losing weight slowly, the bike seems to tolerate my 220 pounds just fine. The bike has been used by several family members ranging from 5'5" - 5'9".
So no backwards compatibility for the cranks?
