I just love these straight to the point product reviews, great content dude keep it up!
instablaster...
Thanks a bunch. Great vid. Beauty upgrade.
How can you release the lock ring on the left arm? I can adjust the crank with an Allen key up to a point where the lock ring has to be loosened
Glad I saw this video before ordering! I was hoping to use my existing Stages power meter but the XTR left crank arm attachment is completely different! Why have they done away with the two pinch bolts? That's annoying!
How much weights for the crank arm for shimano xtr vs the eagel xx1?
Great video and I found it very helpful
Thank you. Great video
Thanks that was useful. Shimano documentation is a bit secretive about how they get installed.
Jed would you do a review on the Renthal Fatbar Carbon 35 stealth pls to see what they look like Cos there’s no videos of them thanks
For the chainring lockring.. it isn't exactly 1pc like in this video. It is 3pcs. There is a thin metal spacer on the arm side, then the main lockring, and then a small rubber/metal spacer ring seal. If it comes off the lockring during maintenence, the metal side goes against the lockring, and rubber side goes against the bottom bracket after talking with Shimano.
On your crankset is it 120mm spindle length, cheers?
Thank you for the tutorial. 👍
can you use this Chainring to SLX crank? M7100?
I have this exact crankset on my XC, it’s so beautiful 😍
Great video, note Shimano advise spacer can go on either left or right side. If chainring needs more clearance from frame then put it on drive side otherwise it’s as you have detailed.
How about the bottom bracket spacers?
Oh really. Do you recall where that’s documented ? Thanks
Shimano works and it looks sexy. I'm 6'1" and 135kg and that 24mm spindle is a bit soft for me
Thanks for the video. Very helpful. I’m trying to remove my M9120 crankset. Can you comment on how to remove the non chain drive-side arm? How far do you unscrew the 8mm hex before you can remove the crank arm?
Undo the preload then unscrew the 8mm till it spins with ease and the arm should remove with little effort.
Hey thank you for the info i just got a 2020 SC Tallboy, I got xt1x12 with XTR crankset,love all the components and like you said there is no review or details on these cranks thanks again.
Thanks Luis, the Tallboy is a nice bike.
I am unable to remove the no-drive side arm from my bike: I loosen the 8mm allen, it turns about 1/3 revolution and binds there. I assume it is supposed to be a self-removing crank (the bolt pushes against the serrated part of the crank arm. I noticed on a previous comment you said to undo the preload first, is this right hand or left hand thread? Thanks.
I am having the same issue. Do you just keep going or do we need a special tool remove the serrated part?
Thx for posting. Trying to decide between 9120 or a carbon crank (like a RF Next), given less weight and stiffness for carbon but potentially more durable aluminum XTR. Any thoughts?
I have personally stopped riding carbon cranks as they don't last with type of riding I do.
Carbon is NOT stiffer than aluminium.
Thinking about buying these and using a 11 speed cassette, will this work? Is there a specific chain I should buy
Yes, any Shimano compatible 11speed chain will work. I always liked the XT CN-HG701
Hi how to remove the none drive crank ? Aside from the 8mm allen key, what SPECIAL TOOL do i need to use?
Hi Eric, you only need to use an 8mm to install or remove it from the bike, the 8mm nut is designed to stay in the non drive crank arm and a 11 spline bit socket is used if it needs to be replaced.
@@jedmtb Hi Jed MTB, im quite hesitant to do it, could you show us in video. For the tools i do even have d park torque wrench, however.....after freeing the 8mm nut with few turns it seems d 11 spline socket was preventing it to be loosen more? Sorry i just wanna be safe than sorry just to avoid unwanted expenses when doing PMS, will appreciate your video tutorial... please.
Hello. Just to clarify, the cranks are also compatible with 1x11 speed shimano xtr drivetrain?
Yes they are.
Have you ever situation where preload adjuster get loose during bikening? I noticed that sram has a little bolt to tighten preload system shimano don't:/
Not any issues with it coming loose, I check it every few rides as I've had problems with the sram and RF ones in the past as the adjusters normally crack around the bolt. Replaced them with metal adjusters to fix the issue.
That socket which you used on the chainring, does that also fit the bottom bracket ?
No, it's just for the chainring lock ring.
Have you found any Crank Arm boots to fit them yet ged?
Yes, let us know!!
Hello i'm planning to upgrade my XT M8100 Crank to XTR's, I have a 52mm Chainline BB Shell Measurement of 68. Should i Buy the M9100 or the M9120, Thanks so Much
I would go with the M9120 as it has a similar Q-Factor (168mm) vs the XT’s 172mm
It does not say in the manual which directions for the 8mm Allen ... I guess it's normal threaded?
Hi, it’s standard thread, right to tighten and left to loosen. It can be very hard to remove
Have you ever heart about play on the crank in an up and down movement? So not from the left to the right but just the left crank arm who has play on every pedal stroke. Like 0,5cm of movement. Anybody please help:)
@@svenraats2811 Has the bottom bracket bearing been checked? Is there any wear on the axle on that side?
Hola, buen vídeo. ¿ Sabes cuánto pesan esas bielas sin montar el plato, (solo las bielas ) ?. Saludos.

@@jedmtb Gracias
so do you put these directly on your bike, or wear them around your neck for a few weeks first.
Neck first always :) still waiting on my new frame to get these fitted.
@@jedmtb ooooh, new frame, and do tell, what's in store??
@@thecount1001 Will be revealed shortly
I can't budge that 8mm bolt to remove my cranks even with a breaker bar
Where are the bottom bracket spacers intended to go? Thanks.
Depends on your frame, here's a link to the manual. BB spacers (page 10) Axle spacers (page 16) si.shimano.com/api/publish/storage/pdf/en/dm/MAFC002/DM-MAFC002-08-ENG.pdf
@@jedmtb Thank you very much! I'm amazed that Shimano doesn't provide these instructions in the box! But now I know where to look.
Can you get the Shimano 11/12 speed cranksets to work with 9 speed gears?
Yes you can use it.
@@jedmtb I pressume I would need to change the chain ring to support 9 speed chains?
@@m.allmark I like to use Oneup's rings www.oneupcomponents.com/collections/switch/products/switch-shimano
@jED dont suppose you know the part number for the spacer do you?
Here is an exploded view with all the part numbers. dassets.shimano.com/content/dam/global/cg1SHICCycling/final/ev/ev/EV-FC-M9120-4379B.pdf
Thanks🎉
Can i use this chain ring to m8100 sir
Yes you can.
How can M9100 and M9120 having 2 different Q Factors be both boost chainline spacing?
They just extend the crank arms out 3mm on each side but keep the chainring in the same place.
@@jedmtb Ah I see, is Q Factor more of a concern for road cyclists? I've never heard of it being much of a topic for MTB. Is Q Factor dependent on one's hip width and how far apart their feet is set?
@@GokkunGuru Road cyclist normally like narrower q factors for aerodynamic reasons, yes you pick the size based on how wide your foot stance is.
My crankset didn’t come with the non drive side spacer what the hell?
Hi, neither mine. Did you manage to sort it? I have a BB with some spacer so perhaps that will work, hmm
Sexy cranks man.
C'mere can I ask you something please - will these go on my 9 x..
Cheers 🍻👍
my xtr M9120 crankset is in perfect alignment but the non drive side seems need more extra spacer
Have you installed the spacer and ring on the nds? Item 5 as shown in this exploded diagram dassets.shimano.com/content/dam/global/cg1SHICCycling/final/ev/ev/EV-FC-M9120-4379B.pdf
@@jedmtb do i need to change my bottom bracket? I did not change my original (shimano BB 71 press fit) on my canyon lux trail cf6
@@reygacutan3018 You shouldn’t need to but might be worth asking canyon what they recommend.
Can you use the FC-M9120-B2 on a non boost frame?
Yes, Shimano claims that it will work on a non-boost frame, the chainline is 52mm and the optimal for non-boost is about 49mm so you would probably get some extra noise on the largest cogs.
Thanks for the input. One more question, how about the FC-M9120-1? What's the diff between -B2 and -1?
@@alvingalut1492 They are the same crank arms, the FC-M9120-1 is a single ring and the FC-M9120-B2 is a double ring.
@@jedmtb because there is a good deal I saw fir tge -B2 cranks online. I am thinking to buy It and just take out the double chainring and install a single 34T chainring. Instead of buying a crankarm withoit chainring at an expensive price. What do you think? Should I go for the double and just change it to single chainring? All I am worried is if there is a diff between the -B2 and -1.
@@alvingalut1492 If you can get the B2 for a good price, I'd buy it and convert to a single ring.
So you don't have hope crank anymore ?
Yes I still have the Hope Cranks they are for a different bike.
I got my hope crank with Hermes today but I'm still waiting for bottom bracket
Or would do the hope Carbon bar pls I’m stuck between the two I’m mainly running all hope but there not a lot of reviews on the hope Carbon bar thanks
The Renthal stealth is matte with glossy logos, it just looks black from a distance, I find Renthal bars too stiff for me but others seem to enjoy how direct they feel, I don't have 31.8 stem to test the Hope bars unfortunately, oneup also make a nice bar as well.
Jed MTB yeah I think I saw a review on tredz about the hope bar is good but the performance is lacking abit at high speed is doesn’t absorb the pumps as well
Do you know how tight Renthal bars to got be Cos it says you gotta get them fitted by a qualified mechanic thanks
@@tristans432 Recommended torque is 5nm
Is that for all bolts or just the ones on the zero clamp and bottom clamp thanks
Thanks for the info, I can’t believe there are ZERO instructions included in the box. At the very least there should be a checklist of the items and what they do. I can’t believe Shimano charges this much money and can’t supply some basic instructions. The paperwork in the box is just some useless garbage.
Yeah, that is a shame. Especially because you can get *excellent* detailed instructions in PDF on si.shimano.com - the "DM" one. Not sure why they don't just print them off and include them in the box.
@@PetrSedlacek They already have so much paperwork in there so I am happy they don't generate even more waste. For some parts the DM is very long. They should just include a card with a QR code or some information where you can find the DM.
@@Freddy3792 You're right, I agree that would be better. The paperwork they do include is usually pretty useless (although it might be required by law). So a QR on the box with a link to the PDF would be ideal.
I don't understand why shimano has silly big boxes, other wise great boxes but way too big packaging. TThis one was ridiculous too.
agreed. it's part of the marketing sadly. buying an XTR crankset is like going to Mercedes dealership, or similar luxury experience. maybe someday these companies (and their customers, we're part of this problem) will get it.
WONdERING y nOt go for carBon for the money
I've had too many failures with carbon cranks unfortunately.
focus that camera man and give us some weights. more info
Ahoihoi
So BS. I just paid over $400 for this crankset and there is no tool that came with it so now I have to go out and buy one. Lame job @Shimano.
Dude, didn't you watch your own video before posting it? Focus man Focus! Awful, gave me a headache
Give it a break, its not the bloody BBC ffs
