Quick and Easy - How To Install A BSA30 Track Bottom Bracket and ROTOR ALDHU Track Crankset

I recently purchased a brand new BMC TrackMachine TR01 (full breakdown coming soon) and a brand new ROTOR ALDHU Track Crankset. The Bottom Bracket for a BMC is a BSA30 Threaded Track Bottom Bracket. Luckily, when you order your ROTOR Crankset there is an option to order the proper BSA30 Track Bottom Bracket with it.

This video is a video on how to install the BSA30 Track Bottom Bracket on a brand new track framset as well as install the ROTOR ALDHU Crankset into the bottom bracket.

Note: I experienced some tightness in the crankset after the install and realized that the manufacturer torque spec was a bit high to allow the cranks to spin freely. I'm unsure if that means that they needed to be backed off, or what the particular issue was, however, it felt like everything was just a bit too tight.

I reached out to some local mechanics and no one had a definitive solution. My solution was to back the torque off completely and retighten right up until they no longer spun smoothly, then back the cranks off to just before this. I test rode the BMC prior to racing, and subsequently have raced the BMC on the ROTOR ALDHU Crankset with zero issues. Everything spins fine and I've had no problems, personally.
