Rotor TRACK30 BSA Bottom Bracket

The Rotor TRACK30 BSA Bottom Bracket is a high-performance bottom bracket designed for Rotor 30mm spindle systems. It is especially well matched with Rotor track cranksets, helping bring out the stiffness and lightweight performance of a 30mm spindle setup.

This model uses stainless steel bearings for low friction, smooth rotation and reliable durability. For single speed and track bike riders who care about pedaling efficiency, direct drivetrain response and stable power transfer, bottom bracket quality plays an important role in the overall riding feel.

With an approximate weight of only 96g, the TRACK30 BSA keeps weight low while maintaining strength and rotational stability. When paired with a stiff and lightweight 30mm crankset, it helps the drivetrain perform efficiently during acceleration, sprinting and high-output riding.

This bottom bracket is compatible with BSA / JIS threaded systems, 68mm shell width and English / Japanese threading. It can be installed on many traditional threaded frames, making it suitable for both classic frames and modern single speed builds.

⚠️ Please note: this model is designed for BSA / JIS threaded systems.
⚠️ BSA30 cups are not compatible with BB90 or BB89 frames. Please confirm your frame bottom bracket standard and crank spindle size before ordering.

If you are using a Rotor 30mm spindle crankset, or want a lightweight, low-friction and smooth bottom bracket for a single speed or track bike build, the Rotor TRACK30 BSA is a strong choice.
