The front shifter could be dead... or not


Introducing the Hammerschmidt.

Truvativ developed two Hammerschmidt models. One is an all-mountain build comparable to Stylo cranks while the other freeride build uses cranks along the lines of the venerable Holzfeller. An included shifter looks remarkably similar to a SRAM X.0 model, but has only two positions.

There are several advantages to a single-ring, planetary-drive crankset. Riders can shift gears under incredible torque loads, while the cranks are stationary, or while pedaling backward. During the official unveiling, SRAM spokesman Greg Herbold was quick to point out that he could even shift while airborne. And shifting is more instantaneous than conventional derailleur systems—the gear mechanism uses a set of pawls to quickly engage a ramped gear, and they do it faster and more reliably than a conventional chain with a row of lifting ramps.
