Thanks for answering bottom bracket size and spacers. I bought a BB for a 68mm frame and no spacers were supplied and couldn’t understand why. Now it’s sorted
"Adjustable Spanner" here in Germany is called "Engländer" which translates as "Englishman"....-:) Thank you Englishman (hope that this is no offence due to any posible walisich, scottish or north irish or whatever issues) for your videos anyway
I noticed this set doesn't come with dust caps, is this normal and do I need to buy. Seems a shame as it seems like something that should have been in the pack. Thank you ffor the vid dude!!
Hi! Thanks for very helpful video, I'm uninstalling my cranks and I've got no idea where to find that small tool for the plastic bolt from non drive side, any idea? And also what are these bolts for the chainring? Because I'm trying to grease everything as my crankset (1 month old) squeaks as hell.
Just fitted one of these into an aluminium Ridley Kanzo A frame and it was a nightmare, very tight fit and I fear there is a very very slight angular misalignment on one side of the bracket, what can I do? Will it effect the crank? It is very slight... Roughly quarter of a mm.
Probably won't affect the crank but may lead to faster BB bearing wear. In my experience sometimes Hollowtech BBs go in really easy like this one did, others need a bit more persuasion. Usually drive side is tighter than non-drive. As long as you didn't cross-thread it you're good. Ideally you want to clean/chase the threads on the BB shell before doing it but that's a job for an experienced mechanic with the right tools
I have one question regarding the m8120 cranks (according to the chart i need that one because of my 148mm rear axle). In Shimano's dealer's guide there are two 3mm spacers, that i should fit in between the bottom bracket and the left and right crank arms. These spacers are comes with the cranks (i have not found any information about it.) ? That was a great video by the way :) Thank you !
@@raoulwoodruffbecker1518 8100 and 8120 are both 148 boost. 8120 favors more tire and stay clearance. 8130 is super boost. 8120 can be moved around a bit with different spacers.
what bike have you got and what did you go with I am fitting slx 7100 crank and 12-speed cassette drive train to my giant trance 2018 now and am in the same predicament, what people say is 52mm chain line 7100 will be ok on 30t 32t chainrings but if you want bigger or oval go for the boost only crank 7120 . the slx 7100 52mm chain line is fitted from the factory on a giant trance 29er 2021 model !!!!!
Hi. I want to install the m8120 for boost axel. Do I use the spacers if I want 34 tooth chainring or more as 32 tooth chain ring just fits or do I use spacers anyway?
I have boost axle 148mm and 68mm BB. Shoud I put two spacers on chain side and one on the opposite? Or there should be all three spacers on the chain side?
I just bought these cranks off ebay but didnt come with that center cap? Can i get away without and just make sure the allen key bolts are tight or do u need the center cap? Thanks :)
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.
@@FreeToCycle thanks for the response, much appreciated. I’m thinking of adding in the Shimano Deore BB52 and add in an 11 speed 32t Shimano Crank (most likely SLX because they’re easier to get my hands on in Australia as opposed to the Deore which are more plentiful in stock in the 12 speed) and run with a mix of SLX and Deore mechs across the cassette (SLX 11-46t), chain and rear derailleur set up... but use an XT shifter.
i have a shimano deore crankset like yours and i have done all the steps correctly and somehow the non drive side crank still works its way off . any suggestion why this maybe
I thought this plastic ring on the non drive arm was a dust cap :) And I almost threw out this plastic locker plate. I am still not convinced that locks on to anything.
I have a marlin 5 7 speed. Broke my crankarm. Non in stock for months. Someone's trying to sell their marlin 6 8speed crankset, shifter etc everything but the frame and the wheels. Is it compatible? Are they different rims? Should I go for it?
Excellent Video!!. Please could you post the product code / part number for the Bottom bracket that you installed in the video? Is your bike frame Boost or Non-boost? Thanks,
Finally someone who lets me know how many spacers to use. Thanks!
It’s amazing how many of your videos have helped me work on my various bikes that seem to have the same parts as yours. Thanks!
You're my favorite bike repair channel. I've watched so many of your videos while upgrading my Specialized Pitch.
Amazing. Just the step by step video I need! Thanks 💥

Very informative and pedagogically done! Thanks!
How many newton meters on the torque wrench?
Late to the party, but thank you for the informative video. Helped me complete my drivetrain install.
I learned something today. Thank you!

Every new bb bearing i have checked has barely any grease. I always add dura ace shimano grease to them. Never had any fail.
very good images and explanation. THANK YOU

If a bike comes with one of these on, is the frame compatible with a BSA DUB 68/73mm bottom bracket?
Great video. Thanks!
Does that tool come with the crankset?
Thanks for the video. Really helpful.
Sorry was this a boost frame (148) ? you fitted to I see went with 8100 cranks which I'm guessing is a 52mm chain line?
what kind of torque wrench do you use there…
For 68mm not using any FD or bash guard, should I still use 2 BB spacers on the drive side?

@@FreeToCycle many thanks!
I bought the XT M8100 boost cranks and the oneup oval chain ring. Chain ring doesn't say boost but the cranks are. Should work OK?

@norbert tumpek no so you want the fc-m8100 that is already boost size of 52 mm chain line and 172 q factor. fv-m8120 is super boost plus I believe.

Is that crank really necessary. Can I use my 11sp boost xt on the 12 drivetrain?
Can I use Deore XT 12 speed crankset with my 10 speed cassette on my giant talon 1?
Better off fitting the M8000 crankset, that will work fine with a shimano 10 speed chain!
I have boost axle 148mm and 68mm BB. Shoud I put two spacers on chain side and one on the opposite? Or there should be all three spacers on the chain side?
Two spacers on the drive side and one on the non-drive side!
@@FreeToCycle Thank you very much! :)

You will need the crank arm fixing bolt! They are available separately you can find them online.
Thank you so much for this video...it is extremely helpful
Can I put it in 1×10?
Where can I buy chainring 36T for my m6100?
Good video - I have the m8100 cranks to fit my boost frame. Do I need to add a spacer on the crank spindle? Seems to need one
No spacers are available to fit the crank spindle!
can the chainring be used on the deore m6100??thank for your support
Yes!!
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?

Not compatible with the GXP cups! One side has a different diameter bearing.
@@FreeToCycle thanks for the response, much appreciated. I’m thinking of adding in the Shimano Deore BB52 and add in an 11 speed 32t Shimano Crank (most likely SLX because they’re easier to get my hands on in Australia as opposed to the Deore which are more plentiful in stock in the 12 speed) and run with a mix of SLX and Deore mechs across the cassette (SLX 11-46t), chain and rear derailleur set up... but use an XT shifter.

If the splines are damaged inside the left hand crank arm it will cause the arm to come loose!
@@FreeToCycle no the splines are still good as the crankset is only a few months old
Does deore xt is compatible with shimano bb52 mate?
And if my frame is 73mm what would i put in the thicker spacer or the thick one?
Yes the BB52 is compatible!

It depends on what size frame is it 27er or 29 what is your frame
..then go for it candy..
Crank 32t ?
Nice video. Still I don't get which I have to buy between XT 8100/XT 8120/XT 8130...
does the bb come with the plastic spacers ?
Yes!
@@FreeToCycle what size are the spacers ?? are they 0.7mm
Sir can I use m8000 BB to a Shimano XT m8100 crank?
Yes!
Amazon links would be helpful for viewers as well as yourself. TY.
would this crankset work for a 1x9 set up ?
No!
1 x 10 ?
Confused. Shimano say a 1.8 and 0.7mm driveside spacer for 73mm bb width. (2.5mm then)
You have no spacer. What's right?

Can I use Shimano Xt with DUB BSA ?
No!
@@FreeToCycle what BSA BB can fit for my bike?
Can you recommend one?
Excellent Video!!. Please could you post the product code / part number for the Bottom bracket that you installed in the video? Is your bike frame Boost or Non-boost? Thanks,
The bb is a Shimano XT M800 BSA, non boost.
