![[Обзор]Shimano GRX400. О трансмиссии после 3,5 тыс. км.](http://i.ytimg.com/vi/AMt_svq7-R8/mqdefault.jpg)
Ive got the GRX810 2X10 on my new bike,love it,love the brake hoods they are a great place to hang on and go fast...I stuck a 11/40 XT Cassette on mine and that is the bomb. Bolts right up and no problem. 11 speed is nice,brakes are perfect.
Gravel riding is very popular here in Australia. Perfect conditions in the outback for long gravel rides or touring.
Yes we needed it! Makes so much easier to make touring bike build with great range of gears without the need of mtb parts, bar end shifters or tan pan bodges
Thanks for this very informative clip!
Late to the game, and not low enough gearing. On a fully loaded touring gravel bike, 31-34 is not low enough. Many who need lower gearing have already found solutions from the aftermarket. On my touring/do it all bike, I use absoluteblack 46/30 up front on a Shimano crank and 11-42 Shimano cassette with an XT 11 speed RD and Wolftooth Tanpan. Dura Ace 11 speed brifters. Works superbly.
Yes we need it, i got the 600 and its amazing, clutch mech is must have on gravel. Gear ratios are perfect on gravel / trails, but on tarmac sometimes i run out of gears, rarely tho. Its also nice that these have "3 positions" on 2x front shifters. 1 for big ring, and 2 for small. The extra is that if you have small ring on front and chain crossed to also small on rear, it wont scrub against shifter 👍 theres a fine term for this, just cant remember it now.
The feature is called "trimming". You are "trimming" the FD position. I have it on my old 9spd Tiagra road bike. I also have gear indicators, and I can see the needle move slightly when I trim. GRX does NOT have any option for gear indicators, which annoys the heck out of me.
I am very happy now with my new 105 group set. But the small crankset looks interesting. Maybe next year.
For me, the most important improvement is a 30t-31t chainrings (finally!) I think gravel and bikepacking going hand to hand not only in Poland, but everywhere, and we really need lower gears for a long rides with a bikepacking bags and other stuff on our bikes.
You are awesome man✊🏾
A hybrid MTB/Bikepack would be easy and all the levers would be appreciated.
Swapped back to ultegra cx/rx & not looking back.
Apart from keeping the existing lineup all they needed to do was add a 1x specific long cage derailleur of the ultegra rx.
GRX is more of a marketing ploy to generate income then anything else tbh.
There's tons of 1x chainrings available for shimano ranging from cx/gravel from wolftooth to the monster 56+ from stronglight & aerocoach.
Cool video. Hi from Russia!!!)
Funny really .. we had gearing for adventure bikes back in the day when you could get an awesome 3x Shimano 105 crankset .. it's just something that seemed to fade away and anyone that wanted to seriously tackle adventure riding was left to create their own frankendrivetrains! This isn't an invention ... it's something forgotten coming back!
Hi, just curious why wouldn't you get Di2? Thanks!
Big price, small cassette so a 1x option pretty much eliminated. It's amazing that Microshift have this covered better than either of the big-S brands.
There are a great many excellent gravel trails here in America due to the rails to trails charity. Gravel biked seem to have brought cycling back full circle. In the 50's you just had one type of bicycle that could basically go anywhere. They then specialized into road bikes and mountain bikes. They now seem to be coming back around now to being fun "go anywhere" type bikes. Tires got extra skinny and extra fat on bikes now they are back to being somewhere in the middle. This comes with all the technological advancement that developed over the years with cycling though. I am sticking with my 9x3 gears though, I hope that will eventually come back around too.;p
Yes you need it.
Gearing still not low enough for touring and adventuring riding. Those auxiliary brake levers might come in handy sometimes, especially novice or some female riders.
Hi. Can I change the Shimano shifters from the trouny thumb Sl A050 , 3/7 speed tourney zx to sti Shimano trouny shifter can I only change the shifter at the the Handel bar or I need to change all the system thanks
Do the rear derailleurs work with tiagra/105/Ultegra shifters? I currently have a 105 (7000) group for cx, but I'm very interested in that clutch
Hello could you do a review of the Campagnolo Centaur 11s and talk a bit about compatibility with Shimano 11s parts like freehubs?
Can I swap my existing Ultegra sub compact 2x11 50-34 crankset for the new GRX 2x11 48-31 cranks. My existing group set is currently all Ultegra 6800
Looking for a 3 chainring touring group to build a steel frame. Can't seem to find one. A double might work but hate big gaps in cassettes to accomadate wide ranges.
try the 3*10 Deore? 48/38/26 option available...there is one more, I think, in 40/30/22. If you wanna go cheaper, go for Sora (road Bike groupset) 3*9, available in 50/39/30 and 11-34/36. I am using this and works brilliantly. Don't really need the 50t but still, offers plenty low gears available
Deore treking crank 48/36/26 & 11-34, Tiagra 4703 get me anywhere I need to go.
I have an Ultegra 3x9 that I replaced with Dura Ace. Do you want it?
Can Tiagra FD be a replacement for a GRX FD?
We definitely needed those 48/31 and 46/30 cranksets, as well as the higher capacity rear derailleurs. And not only for gravel riding, but also for road riding in properly mountainous areas. Just wondering about the prices for those cranksets though, I hope they don't end up being more expensive than equivalent Tiagra/105/Ultegra cranksets, especially since they are heavier.
Simply train more, I have a compact and a 11/28 cassette. I live in the alps, conquering a mountain is just the best feeling, but olny if it repays the hard work done... Seriously, a compact with 11-32 you can go on a 9-10% climb without too much training
@@LucaBonato how much do you weigh, out of curiosity? Because as a guy weighing around 85 kg (and with an FTP of 260W and a maximum power of over 1100W), I beg to differ that a 34/32 is enough as a minimum gear. And let's not forget there are quite a lot of slopes way over 15% in the Alps and that some of us don't climb out of the saddle.
@@LucaBonato also, climbing one mountain is one thing, yet doing rides with >200 km and >4500m of altitude difference while weighing way over 80 kg is a whole different story.
@@11robotics 70/71kg, seriously 15% is seen on the zoncolan or it's just less than 2-300m in the roads where I live, normally on back roads. Usually cyclist goes for climb at an avarage of 6/7%, avarage I repeat. If you do the zoncolan every day it's better to have mtb's gears. It's always a compromise, and seriously if you do 200km you are well fit. Try losing some weight if possible. Or just shorten you rides ahah
@@11robotics ps: 200km with 4500m of altitude gain is like doing a giro d'Italia stage just for comparison. We are amateurs, just enjoy the ride and everyone has their limits. Having bigger cassettes is just stupid with road cycling. Imaging using a 50t and having 2-3 teeth gaps, your rpm would go down by 20-25 killing your legs
Can you run an 11-46 cassette with the 1X GRX system? Or only up to 11-42? Thanks
@AG Coarseman what about putting a rear mech hanger extension?
Yes, with a roadlink
are the new chainrings compatible with existing cranks? (like Tiagra 4700)
that new chainrings, not use the classic 5 bolts b.c.d 110/130. use the new 4 bolts of "newer" crank series R
@@KyriaxWitch Yes (maybe) and No. For 1x crankset it may be the same as the "4-bolt R-series", but for 2x it's GRX-specific 4-arm 110/80 mm BCD (bike.shimano.com/en-EU/product/component/grx-11-speed/FC-RX810-2.html)
Can you recommend a flat bar shifter that that will properly pull the GRX 11-spd front derailleur. I like the idea of a flat bar gravel bike...
Moving the chainline out is not a great idea. It will make the noise for 1x in the easiest gear louder since the distance is now greater.
As far as I know they only moved the chainline out on 2x stuff to make more room for the rear tyre because of the FD. They list the chain line on the 1x stuff at 50.1mm which is not really far off from the 49mm that SRAM uses on 1x road groups and/or non boost stuff.
Boni Hollóssy I’ve heard someone say (maybe it was this video I watched a few) the chainrings go on the same crankset so you can swap between 1x and 2x. That would mean they both have the same chainline.
@@jonathanzappala Not necessarily. For example with SRAM the 1x chainrings come in different offsets, while the cranks are the same. Both boost and non boost bikes use the same cranks, but the boost chainrings have a 3mm offset, while the standard chainrings have a 6mm offset. So different chainline, same crank. Aftermarket companies like Wolftooth also use offset chainrings so you get the correct chainline when you convert a 2x crank to 1x for example.
Boni Hollóssy I just checked the website shimano says the FC-RX810-1 has a chainline of 50.1.
@@jonathanzappala That's what I said, and also added that the SRAM road 1x stuff uses 49mm. 🙂
Can i use shimano road fd for grx 2x cranks?
Dan Diaz apparently not. Grx has a wider Q factor.
105 vs grx for gravel bike? I want grx but money tight so might have to go 105
The price difference is negligible. 640€ for 105 and 680€ for GRX 600.
@@GreySectoid thanks Terry I went for a mix of grx 600/810 in the end.
In gcn they mentioned something about extra buttons on shifters to control your lights, or head unit or smth. I would like that for any road shifters. Last autumn I bought a head light that has the remote button with a wire. And then I realized how good it is to have it. Unfortunately my light only had one button to change brightness. But I really would need hi beam and low beam, when riding on road. But for that I still had to let go handlebar and find the button in dark. And on snowy, icy road it was difficult to do.. Keep eyes on road and then search the button with other hand to switch the low beam.. So I sometime just kept it on hi and adjusted the brightness, hoping that it won't dazzle if the lumens are low.
One word: Deore...
deore is old and i think will get a refresh in 2020
overpriced ofcourse
Designed for flat bars, derailleur not compatible with drop bar shifters, geared a bit too low for a bike that might also see pavement. How is Deore relevant again?
30:34 is not enough for clibing, and not just for me!!!
I should say, that this new grx is not very clever groupset.
I couldn't agree more. Note that I have been told by a bike shop that you CAN actually use a larger cassette, if you avoid crosschaining the small chainring with the smaller cogs. Unfortunately, lacking gear indicators, I think this would be tricky. The electronic shifters automatically avoid crosschaining, so that's something.
I want the lowest gear ratio that Shimano can provide. What will it be?
Probably GRX 400 with 46-30 crank and 11-36 cassette.
did we need it? well, someone needs to learn a litte about MARKETING DEPARTMENTS, because before GRX, it was impossible to ride a bicycle on dirt roads... even though dirt roads were around before PAVED roads.
and before "gravel" bikes, there was no possible way to ride a bike on unpaved, dirt roads. no way, no how.
and certainly a cyclocross bicycle could never EVER be ridden on unpaved roads. nope, need an entirely new, and virtually identical bicycle for those dirt roads.
my god, i should have taken up cigarette smoking. riding a bicycle has gotten stupid.
this guy gets it
Do we need bikes? Well, someone needs to learn a little about MARKETING DEPARTMENTS. You can always just walk instead. What a sham.
is a capitalism man, LOL.
look on Wikipedia, search for bicycles types and you see a lots of sub category of same bike discipline. for me cx, gravel, hybrids and touring bikes are same. with different names.
but the market tell another history.....
When I was a kid I certainly never rode my hand-me-down step thru bike on dirt roads, never ever, wasn't even possible as it didn't have boost or suspension
SRAM is going full steam ahead with 12 speed and Shimano is still putting out 11 speed drivetrains... Too little too late.
Kind of agree with you. With delays in production of XTR M9100 components, the migration of Microspline standard to road and making 12-speed groupsets for road will not be in sight in a year or two...
I'm freaking sick of my Rival 1 drivetrain. The only reason I haven't set it on fire yet is because I was a dumbass and I paid for it with my own money. Their 1x12s are just as bad and in some aspects even worse, but hey, it goes to 12! Gimme a wide range 2x10 or 2x11 with low gears any day instead.
i wait too for something really new, to spend money. shimano still sleeping and maybe lost opportunity to make a grx with hubs like xtr and 12s.
@@RicoLee830104 maybe shimano still waiting for SRAM product, to migrate... don't understand this market choices she's make. just SRAM launch an 10- something gravel groupset, everyone maybe forget quick this grx
Dang. They were about a week late. The bike I am building will have a SRAM 1x system. In fact, the bottom bracket was just delivered.
Sorry, Shimano.
it will be available only in the end of summer. so do not worry, sram is great
Hope so. I have very little SRAM stuff.
I just installed the bottom bracket. For a novice mechanic like me, I’m taking the small victory.
The GRX-810 is junk. First off, it will randomly jam the cable and stop shifting to most gears. The issue is resolvable, but it will likely take a while to infer the cause of the issue. Furthermore, the front brake stopped working 4 months and less than a thousand km from purchase. Bleeding worked for one brake but at the cost of a stripped bleed port thread in the lever base. The port screw won't ingage. The other one does not work, bleed all I want.
The worst groupset I have ever owned.
Hey dude im first
Hello anyone have xtra groupset
Pls gift me pls
most non sense groupset ever, pure money grabbing. any mtb drivetrain works on cx,gravel or anything offroad.
many comb of chainrings from deore to xtr.
Innovation? an 31t chainring and extra hydro brake levers? really.... put an flat bar with mtb hardware and be happy.
Now you have the combination of wide gear ratio and road bike STIs. That is new.
@@christophh.1246 for that i have to buy this new GRX RD and STIs... come on!
why no make an series of STI compatible with already available mtb RD and cassettes range? think guys, opportunity to make more money with old hardware with pretty facelifts.
How exactly does a MTB entire drivetrain work on a cx or gravel? 10/11 speed MTB rear derailleurs are not compatible with road shifters. If you want to use large cassettes with road rear derailleurs, you have to improvise with those mech hanger extenders, which are a bodge. MTB chainrings don't work on road cranksets, while MTB cranksets are not fully compatible with road/cx/gravel frames because of their significantly higher chainline, meaning the chainrings will be too far out, while road front derailleurs will struggle shifting on the large ring.
What's really important with this groupset are the rear derailleurs that have a MTB-like capacity and work with almost the entire range of current road STI shifters (even Tiagra 4700) and the 48/31 and 46/30 cranksets with chainlines that are appropriate for road/cx/gravel bikes. The new STI shifters and brakes are more of a gimmick compared to the current road offerings, while the new front derailleurs are simply adapted for smaller chainrings.
If I buy their MTB components, Shimano makes money. If I buy the new GRX stuff, they make money. Please explain the difference.
A lot of people prefer drop bars, and between MTB and road gearing there has been a big hole since the disappearance of triples.
@@11robotics not really need to change the crankset and dont need to buy mtb chainrings for works!{updated info} the bcd 110 5bolts road cranks works from "uncommon" 30t and stds 33t; the 130bcd from"rarest" 37t stds 38t and the newers road 4 bolts from 30t chainring, so just select your setup of chainrings you want to use. if the frame has different chainline need to be adjusted with more spacers for use mtb cranksets. many riders here converted road frames using mtb cranks and mtb FD without problems.
to make compatible the sti without extenders exist one "road to mtb ratio adapter" from jitek to use on cable but lots,lots of riders here use road link extenders on gs road RD even on pure road bikes to use larger mtb cassetes or custom/mixed road-mtb cassette.
