So I have some Middleburn R02 cranks that I picked up off eBay. I want to install them with my Shimano BB. Everything is 24mm axle, so I think it should work. My frame is standard 68mm threaded.
I found these instructions on LFGSS: https://lfgss.microcosm.app/api/v1/files/91be8679cbe28a02b2b80ec0a338aeb5d1117584.pdf
The problem is that the cranks can slide side-to-side in the BB, so I think some spacers need to be added onto the axle.
I found these instructions for a Middleburn BB: http://www.sjscycles.com/Instructions/Middleburn/Midleburn_X-Type_Mountain_Bike_Bottom_Bracket_Instructions.pdf
This mentions some spacers:
But is this right for a Shimano BB?
Any ideas?
