ROTOR set out with the goal of creating a bottom bracket unlike anything currently available on the market with a flashy and aesthetically appealing look. The BB1 is incredibly light and is sure not to go unnoticed, and the smooth unobtrusive lines marry perfectly with any type compatible crankset, be it made of carbon or aluminum.

Characteristics:

• Designed to work with BSA threaded road or MTB bottom brackets 
• 100% CNC-machined, 7075 aluminum
• Labyrinth seals prevent bearing contamination
• Designed to work with ROTOR and Shimano 24mm cranksets
• Road 24mm, Road GXP, MTB 24mm and MTB GXP options available
