The same industry-leading engineers who ushered in the origin of smart trainers have joined forces once again to create the ultimate indoor riding experience - the CycleOps Hammer Smart Direct Drive Trainer. The Hammer redefines indoor training and is versatile enough to handle the most intense interval sessions as it is the easiest of recovery rides. It is compatible with virtually any smart device and training app out there and is the perfect addition to any cyclist's toolbox, whether you're a beginner or a world-class podium contender.

The Hammer is ANT+ and Bluetooth Smart enabled so it can not only show you power data and more, but also receive information from training software like Zwift, Training Peaks, and others for fun and realistic-feeling workouts that will change the way you think about training indoors. This direct drive-style trainer eliminates the tire-to-roller contact, and is capable of replicating any outdoor ride from conversational group rides to rolling hills to pain face inducing 20% grades and 2,000 watt efforts. 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 CycleOps' 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. Plus, 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.
