I think it would be a bit daft for me not to use them now I have them, so it will be more a case of when, not if they go on.I had that xtr set up in rapid rise. Probably the best performing gears I’ve ever had!
I haven't set the XT brakes / shifters up yet, so it might make more sense to go with the XTR and if, after a while, I still feel the need to try the others, have a change.
