Truvativ Descendant CoLab Crankset

The TLD CoLab version features exclusive aesthetic designs created in collaboration with Troy Lee Designs. While the performance specifications and robust aluminum construction remain identical to the standard Descendant DH crankset, this model offers a unique visual style for riders looking to customize their bike's appearance.

The Descendant TLD CoLab is compatible with 10, 11, and 12-speed drivetrains. It uses a 1x setup with a direct mount 3-bolt chainring interface, making it versatile for most modern gravity-focused builds.

Yes, these cranks use the SRAM DUB bottom bracket system. You will need a DUB-compatible bottom bracket that matches your frame's shell standard, such as BSA, PF30, or BB30, to ensure proper fitment and stiffness.

The DUB system is designed to create a more uniform interface between the crank, bottom bracket, and frame. For downhill riding, this translates to improved stiffness and better bearing durability, which helps maintain smooth power transfer even under the heavy loads and impacts common on technical trails.

X-SYNC 2 is an evolution of SRAM's chainring design that features a more aggressive tooth profile. This significantly improves chain retention and reduces friction, which is critical for preventing dropped chains when riding through rough, high-speed downhill sections.

The 165mm length is generally preferred for downhill bikes because it provides extra pedal clearance, reducing the risk of striking rocks or roots in technical terrain. If you prefer a slightly different leverage feel or are taller, the 170mm option is also available.
