No problem at all. Since u still with the same brand, just a version upgrade. For changing difference crank set need to take note just the Bottom bracket.Just get back the current same size of ur crank will do. Enjoy for upgrade.
ok mate .. Thx .. But do note the 9000 series crank is meant for 11 speed set up whereas mine is 10 speedThere are some who says ok some say no .. Hoping to see if anyone here is with this setupThx
Yap dura ace 9000 is 11speed crank.Don't worry u are not the first one to do so. 10/11speed not much difference.One of the technical issue is the chain will drop out. with the Difference (but I don't see this is a big issue)11s crank + 10s cassette10s crank + 11s cassette If u use the shimano chain.Google search u will get the answer.
Ok thx .. Using shimano chain should not have chain drop out issue regards
