About the CycleOps Hammer Direct Drive Trainer
The CycleOps Hammer Direct Drive Trainer takes indoor training to the next level. With a 20 lb. precision-balanced flywheel, the Hammer replicates real world inertia better than any other smart trainer out there. In addition, using PowerTap proven technology for accurate power readings, it can measure up to 2,000 watts, allowing it to handle the most intense interval sessions.
The direct drive style trainer eliminates tire-to-roller contact, meaning you can save your tires for the road. The Hammer’s axle compatibility allows you to use any thru-axle from 142 or 148 and is quick-release compatible for frames with fork widths of 130 mm and 135 mm. Perhaps best yet, at only 64 decibels, you can keep your training room as quiet as you like.
