LG1 Race Cranks: Race Proven by Aaron Gwin and the Hannahs.

After a World Cup season's worth of R&D with Aaron Gwin and the Hannahs, we are proud to unveil the new TRS Race and LG1 Race Carbon Cranks to you.

P3 connect

Power Down

Our exclusive P3 Connect™ interface creates a robust, reliable spindle-arm junction. Based on the German DIN 32711 connection found in high-torque industrial applications including tank drive shafts, the P3 Connect™ interface provides 100% surface contact and avoids splined interface degradation – a cause of creaking and loosening.

Preload Perfected

Our Adaptive Preload System™ adjusts crank preload easily and without tools. With a twist, the APS™ expands to eliminate spindle play in the crankset, providing perfect fit and secure preload. Patent Pending.

Chainring Options

All e*thirteen cranks utilize our Quick Connect™ interface to mount chainrings directly to the crank arm. No chainring bolts to creak or seize, and the minimalist design makes for a stronger, stiffer, lighter setup. A Quick Connect™ lockring/BB tool is included with every crankset.

TRS Cranksets

TRS Cranksets are engineered for the rigors of the Enduro World Series and trail riders everywhere.

LG1 Downhill Cranksets

LG1 Cranksets are the DH standard. Pioneered with Fabian Barel for World Cup DH racing, they have evolved into their strongest and lightest form yet. The P3 Connect™ polygon interface creates the most robust, reliable, impact-resistant spindle/arm junction.
