Truvativ Descendant Troy Lee Designs CoLab Carbon Crankset

These cranks use the SRAM DUB bottom bracket standard and are designed for Boost spacing with a 52mm chainline. Before purchasing, confirm your frame is compatible with DUB bottom brackets and that your rear axle spacing matches the Boost standard.

Yes, this crankset is fully optimized for 12-speed drivetrains. It comes equipped with a direct-mount X-SYNC 2 chainring, which is specifically engineered to work seamlessly with SRAM Eagle 12-speed chains.

The carbon fiber construction provides a significant weight reduction compared to aluminum alternatives without sacrificing strength. This results in a stiffer, more responsive feel under power, helping you transfer energy more efficiently on technical climbs and aggressive descents.

Yes, the crankset utilizes a direct-mount interface. This allows you to easily swap out the X-SYNC 2 chainring for a different size or a replacement when it eventually wears down, without needing to replace the entire crank arm assembly.

No, the bottom bracket is not included. Because the SRAM DUB interface requires a specific DUB-compatible bottom bracket to match your frame's shell standard (such as BSA threaded or PressFit), you will need to purchase the correct one separately.
