I have just fitted a Pressfit BB91 to my bike and am using Shimano XT cranks so 24mm spindle.
I would like to change to Sram XX1 set up.
Am i right in thinking any pressfit bb fill fit eg GXP 24/22mm or BB30 as they use the same shell but just different bearing sizes???
I also guess there are next to no differences between both GXP and BB30 and its just to to personal taste.
