I have a bike powered by a Gates belt-drive and a Shimano Alfine 11. It also has an eccentric bottom bracket to adjust the tension on the belt drive, and a SRAM GXP bottom bracket.
The other day, just by following videos on Youtube since no other help was available, I tried replacing the old bottom bracket with a new one… and it looks like I ruined the threading on the drive side of the eccentric BB: I can hand-tighten it, but when tightening it further with a wrench, it loosens again, ie. I can never tighten if fully. It looks like I'll have to buy a new eccentric bottom bracket :-/
The issue: How to identify the brand + model of that eccentric BB without taking it out (I'll need to ride it to a workshop to fix it)? There's nothing written on the sides, short of L/R:
Also, while I wait for a new eccentric BB, I was thinking of applying some medium-strength threadlock in the hope that the drive-side bearing won't move. What do you think?
Edit: I cut the derailleur + hydraulic brake hoses that run through the EBB, and pulled the EBB. It's just a cheap plastic part; According to the bike manufacturer, it's a Prime Aero from a company in Taiwan.
