SRAM DUB BSA External Threaded Bottom Bracket
SRAM DUB bottom brackets are where stiffness meets durability. SRAM has made it incredibly simple by integrating the relationship between chainring, crank, spindle and bottom bracket and provide a single replacement for 30mm and 24mm BB spindles options.
SRAM has created a simple bottom bracket solution that provides better drivetrain performance, increased durability and stiffness without introducing a new frame shell standard to the industry.

- Sealed cartridges.
SPECIFICATIONS:
- Material: Aluminium, Steel
- Weight: 76g (BSA).

- Size: 68mm / 73mm / 73mm Guide

Amazing bb
by hitcho
Easy installation. Smooth and groovy feel and keeps the riding clean in the mean and gritty. Get you're hands on one, things last a lifetime.
Roscoe 8, BB Upgrade.

I destroyed my Roscoe 8 BB, apparently the standard item is for XC only!?
The SRAM BSA, coupled with a SRAM NX crank, is awesome.
MTB Direct were able to provide the upgrade at a great price, and I had the parts in under a week.
