Say hello to TruVativ's HammerSchmidt and goodbye to the funky front shifting of old. With its innovative Overdrive internal transmission, HammerSchmidt offers the security of a single-ring/chainguide setup with the gear range and climbing versatility of a 24/38 double-ring setup. Shifting is super positive and fast and you can do it while coasting, standing still, while pedaling backwards and even under full power! The crankarms are forged from 7050 aluminum for serious stiffness while an integrated chainguide means the chain will never jump off the chainring and you'll enjoy unreal ground clearance, too. Even better, it's as simple as a front derailleur to maintain.
