I need to swap out the cranks on my bike as they need new chainrings and a BB that I can't be arsed to order.
I have available a few sets of Shimano Hollowtech II cranks, but only one BB (BB-5700)
I have the following compatibility questions.
Are Hollowtech II BBs all the same across the range (will the one I have work with all Hollowtech II road cranks?)
The frame is 68mm English thread BB (I think) so this should work with 2? 2.5mm spacers?
The groupset is 9 speed Campag, the cranks are either 10 or 11 speed Shimano depending on which I fit, will there be issues with the 9 speed chain?
I think all should be fine, but don't want to spend a few hours taking apart, reassembling, to find it doesn't work.
