Enduo™ Track Chainring — Narrow

Thanks to a game-changing tooth profile design by New Motion Labs, the Enduo™ Track is the fastest track cycling drivetrain on the planet.

Compatible with any 11-speed road chain, the drive chain has been developed to win Olympic medals for athletes looking to break down barriers, achieve personal bests, and redefine what they thought was possible on two wheels.

Pair with the Enduo™ Track Sprocket for greatest efficiency gains.

Why are teeth missing from the chainring?

It's a common misconception that the teeth design is a skip-tooth system, however this is not the case. On a conventional roller chain, the rollers engage the tooth on a single side and transition to the next tooth by rolling across an oversized gulley, under high tension, to the next tooth as you pedal. This rolling motion creates friction.

With the Enduo™ Track system, two chain rollers ‘lock’ onto the tooth from both sides, creating a ‘dual engagement’ – minimising frictional losses even at high tension as the chain rotates around the chainring.

Why use a 11/128” Chain?

Comprehensive testing shows that the Dura Ace 11/128" road chain is the most efficient chain that works with the Enduo system - exceeding the efficiency data of any 1/8” performance track chain. Any 11/128” 11s chain is compatible with the Enduo™ chainring and sprocket.
