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. 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.

FINAL UPDATE - After a year of owning a Hammer, I finally gave up on Cycleops and their ability to write an effective Firmware update to solve the zero watt dropout and lag issues. Sold my Hammer in January and bought a KICKR. Spent about 500 bucks on the swap. Since then, Cycleops issued another Firmware update and supposedly fixed the dropout issue. It sounds like they finally figured it out which is great for Hammer users. I love my KICKR. Same room, same computer, same ANT+ dongle, etc... and it works flawlessly. Fun to race on Zwift again!
UPDATE - I have been asked by a few people if I am still having the zero watt dropout problem mentioned below, and sad to say I still have the problem. I always keep my Firmware up to date (currently 31.036). Search the support blog on Zwift for Cycleops Hammer and you will see that many are having the exact same issues. I still use the Hammer quite a bit during the winter but racing is almost impossible for me due to zero watt dropouts. I really hope Cycleops can resolve this annoyance. I don't want to sound too negative - it's a solid smart trainer, but it still needs some software tweaking IMO.
Put about 100 miles on this since it arrived a week ago so this is an early review. I will try to update again after a month or so.
The Hammer is built like a tank! Kind of heavy to move around but I prefer something that might survive hours of indoor "hammering". I am built like a rugby player so this is a big deal for me. I had a spare SRAM Red 11 cassette and it was honestly easy to install providing you have the tools and know how to change cassettes. The legs swing out easily and adjust well so you don't have lateral movement. Nothing else to do but jump on and ride.
I use Zwift and the experience is awesome! I have used dumb trainers in the past and I got bored really fast. The Hammer along with Zwift keeps me engaged and focused. I really prefer to ride outdoors year around but the weather has been tough this fall/winter. The watt readings seem very close to reality and the feedback on climbs and descents feels natural. My old trainers hurt my knees on the apex of the pedal stroke when dialed up to max but the Hammer flywheel seems to carry the momentum through the entire revolution - just like outside. I have peaked at 950 watts so far and sustained 500 watts several times. It doesn't heat up at all and seems to handle sprints just fine. As for noise, this is extremely quiet compared to my traditional trainer.
Everyone knows that indoor training can be boring and a pain, but the Hammer is a great tool to hopefully help the cycling maniac get through the winter months!
UPDATE - I have put just over 1000 miles on my Hammer so far. It's still solid and stable mechanically but problems have surfaced when interacting with Zwift. The reason I bought an expensive "smart" trainer is to help with the immersive aspect of indoor training. The Hammer has 2 major issues. First, there is a lag issue where the resistance (on steeper hills) in Zwift will not be felt on the Hammer for a few seconds and then will not get easier at the crest of the hill for a few seconds. It is very unnatural when in races or group rides. Secondly, there is a bad issue where wattage will suddenly drop to zero when changing gears on a climb. I have had multiple issues with this and it's extremely frustrating to come to a stop on a Zwift climb even though I am still cranking away at full effort. It only lasts for a second or so but, once again, this is a major problem when competing. Technical stuff - I have updated the Firmware to v31.31. I have verified with Zwift that my internet, ping, and ANT+ are all functioning correctly. My ANT+ dongle is directly under my left chainstay. I calibrate on the CVT app frequently. My Hammer LED light stays solid white during these adverse events mentioned above.
Search around on the internet and you will see that many others are having the exact same issues and frustrations.
Cycleops said they are aware of these issues. Hopefully they can fix it with a Firmware update soon. I am going from 5 to 3 stars for now and that might be generous.....
It's a bit loud, but again I'm comparing it to the Peleton (which is almost totally silent). It's not unbearable though. The noise is whiney, but not high pitched enough to get on your nerves.
It works very well with Zwift and Trainerroad (using bluetooth). Both programs connected to the Hammer easily.
Hills feel pretty dang real. Sometimes too real. *cry*
