E*thirteen TRS Race Carbon Crank - Gen4


367.49 $ 399.99


Want to hit the trail with THE lightest trail crankset on the market? E*thirteen's TRS Race Carbon Crankset is crafted from the lightest lightweight components, so you can hit the trails at full speed.

In contrast to E*thirteen's Gen3 carbon cranks, the overall profile and volume of the Gen4 cranks have gotten much smaller and slimmer. This also led to a significant increase in heel clearance.

The Gen4 TRS Race Carbon Crank also sees the spindle moved to the non-drive side of the crank for easier chainguide setup and drivetrain maintenance.

The adjustable chainline accommodates non-Boost (142mm), Boost (148mm), and Super Boost (157mm).

Includes an 8mm self-extractor, meaning the cranks are easily removed with nothing more than an 8mm allen.
