Truvativ HammerSchmidt FR Crankset

Ride it. Believe it.

Every so often, you hear whispers about a new product that promises to change everything, only to be let down in some way. Truvativ HammerSchmidt delivers the revolutionary innovation you’ve been hoping for—and it will completely change the way you think, shift, and ride. Truvativ HammerSchmidt opens up worlds of possibilities with an instant flick of a simple switch. This front transmission’s revolutionary design comprises five main components, each working in perfect concert, allowing you to react to terrain in ways you’ve never imagined before.

High-tech? Yes. But HammerSchmidt feels more like magic. The kind that puts you perfectly in tune with your bike and the mountain. No need to think, plan, anticipate. Just ride.

Overdrive

One is greater than two. The planetary gear mechanism at the hart of Truvativ’s new front transmission works like a single chainring with the strengths of the traditional two-ring system — and none of the weaknesses. There are two gears: 1:1 and Overdrive. In 1:1, everything is locked and spinning together. Turn the pedal once and the chainring goes around once. In Overdrive, the ratio is approximately 1:1.6. Turn the pedal once and the chainring goes around about 1.6 times.
