Not what I expected from SRAM

- Jaan 9 May 2026

Now I thought I would spend a few more pennies for a real SRAM bottom bracket but I have to say that I am quite disappointed. I have already had several BBs installed without any problem. This SRAM DUB bottom bracket that keeps rattling no matter what I do. Maybe bad luck and just a faulty bearing? The cheaper Chinese BBs are just as good but without the rattle.
