Drop the hammer on your competition.

While your friends painstakingly negotiate with neighbors and significant others for limited hours of ear-assaulting wheel-mounted 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 claims 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. It's also convertible for compatibility with SRAM XD cassettes with a separately sold XD driver body. 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.

Lifetime does not really mean lifetime.

  • Familiarity: I've put it through the wringer

The actual warranty of this trainer is 1 year. If it breaks after a year you are looking at $375+ to repair it. just got off the phone with them. Never again Cycleops, never again.

Is this electronics or a hardware issue?

Winter training at its best

  • Familiarity: I've put it through the wringer

I recently purchased the Cycelops Hammer and have had an amazing experience. It's quiet, smooth and a great tool for training with apps such as Zwift and TrainerRoad.

This trainer comes with all the adaptors for TA 142 AND 148 as well as QR. They are very easy to switch out as well. The hammer does not come with a cassette. The setup from the box was very easy and also came with a front tire tray hidden under the legs to keep the bike stable which is great as it keeps the whole setup from moving around. From the box all that is needed is chain whip, cassette tool, crescent wrench and a new cassette.

Set up is easy. All you that needs to be done is to install the preferred cassette, mount the bike, plug it in and set up your devices. The Hammer was recognized by my Tacx Ant+ Antenna quickly. Power output accuracy is spot on.

As I already said, the ride is smooth. I can't get over how much more efficient it feels compared to a standard trainers. At higher watts during out of saddle accelerations, the trainer is stable and has no rocking or tire slippage. Noise level is not bad either.

What's it like with Zwift or TrainerRoad? Well, it's pretty much built for it. Suffer on every climb and feel every effort being put into it. Tuck in behind the the pack and feel the resistance lighten up . Break PR's and achieve virtual KOM's. Enjoy the virtual world and simulated real world race courses. All with realism and in the comforts of your home while the roads outside are covered in snow.

However, I won't lie. The Hammer is heavy. Moving the trainer around is perfect cross training for a skinny cyclist.
