CycleOps Hammer Direct Drive SMART Trainer


SKU: 317024

The CycleOps Hammer Direct Drive SMART Trainer redefines indoor training to create the ultimate riding experience. This direct drive style bike trainer eliminates the tyre-to-roller contact, and is capable of replicating any outdoor ride from conversational group rides to rolling hills to pain face inducing 20% grades. 

All of this is done with a smooth, road-like-feel thanks to a massive 20 lb. precision-balanced flywheel that replicates real world inertia better than anyone else. Paired with the innovative, rapid response electromagnetic resistance system and you've got a bike trainer that can cover large resistance changes in a blink of an eye at a whisper quiet 64 decibels. 

The Hammer's revolutionary axle compatibility gives you the freedom to choose any thru-axle or quick release bike now and for years to come. Simply add a cassette, pop off your rear wheel, connect to your favourite virtual training software and prepare to Hammer away.
