ok so ive still got a 26 er (I'm living the retro dream) and it all xt kit except for my crank. as its a 2014 model cannondale it still has 3 rings up front. anyways I'm after a new xt hollowtech crank and was wondering what size if indeed there are different sizes I should get ?
I'm looking to go to 2 rings up front and have been told my 9sp hg chain would be fine (its only a month old so not changing it) is there a specific bottom bracket I need for the xt cranks ? ive heard different splines etc mentioned and am all a bit confused............
They usually? come with the BB included, Hollowtech (HT) 2 now I think. If not: [url= http://www.chainreactioncycles.com/shimano-xt-slx-bb70-hollowtech-ii-bottom-bracket/rp-prod41445?gs=1&gclid=CMKDkLfx28sCFeEp0wod7e0JLw&gclsrc=aw.ds ]link[/url]
Bottom bracket will depend on your frame and the cranks, it's got to suit both.
If you have a Cannondale crak, thee's a good chance you have a more unusual bottom bracket - what bike is it?
It's a cannondale sl4 26inch.
