Sram Dub Press Fit 30/bbright Bottom Bracket Cups Black 79 mm 79 mm Black

The SRAM DUB Pressfit 30 79mm BBRIGHT Bottom Bracket Cup uses 28.9mm aluminium axle which allows the same stiffness as current 24mm steel axles, yet is more lightweight (pair) than 30mm aluminium axles. What's more, this dimension allows a sealed bearing system to be assembled, ensuring greater durability. To really ensure its success, the SRAM DUB is compatible with most current and old bottom brackets, allowing anyone who wants to assemble it on their bike.Features:- Use: MTB- Compatible with: Pressfit 30 70mm BBRIGHT- For DUB axles
