While your friends painstakingly negotiate with neighbors and significant others for limited hours of ear-assaulting wheel-ed indoor trainer time or risk frost bite to round out the required ride time, you'll be dialed in and crushing out watts on your CycleOps Hammer Direct Drive Trainer. The direct drive design saves wheel and tire wear for the road and carries cls of being "quiet enough to ride in a library," which means you can get your intervals in and keep important relationships intact. The secret to the Hammer is a massive, 20-pound flywheel that utilizes electromagnetic resistance to deliver a smooth, realistic riding experience. While no indoor trainer can ever exactly mirror outdoor ride feel, the Hammer is about as close as you can get. It's able to simulate riding grades of up to 20% and is built to handle up to 2,000 watts, which means even the best pro riders won't be able to max the Hammer out. For the rest of us, it means that this trainer has the range of capability to knock out any workout intensity our coach adds to the schedule. Using PowerTap technology, the Hammer is PowerTuned to provide power readings with a +/-3% accuracy while internal cooling mechanisms ensure readings aren't impacted by heat so your data stays consistent across the duration of each ride. It transmits speed and power data to head units and devices via ANT+ FE-C and Bluetooth 4. 0 protocols, allowing you to read data real time and connect with third-party software and virtual training applications for an interactive training experience. The CycleOps Hammer Direct Drive Trainer includes a Shimano-splined freehub compatible with 8-11 speed cassettes. As an added touch, an integrated front wheel tray nestles neatly in the trainer for quick storage and easy access to the appropriate front wheel height when in use.
