The Flywheel is a simple, heavy device to add rotating mass to your Kreitler Rollers. Running off a belt connected to the rear drum of your rollers, the Flywheel creates a more natural road-like feel to riding rollers. Getting up to speed takes a little more effort, and momentary interruptions to your pedaling do not slow you down as much.

There is also an increase in resistance associated with using the Flywheel, due to the belt friction. Check out the Wattage Chart for more details (will open in a new window). The Flywheel works with the Standard Frame only, not the Kompact Frame. Left Side and Right Side versions are available for the Flywheel. There is no difference in performance whether you choose the Left or Right Flywheel. It is a matter of personal preference. Some people like to use 2 flywheels, so we offer both a Left and Right option.

Unleash Your Indoor Training Potential with the Kreitler Killawatt Resistance Unit!

If you're serious about Zwift, TrainerRoad, or crushing your indoor training sessions, the Kreitler Killawatt Resistance Unit is a must-have. This innovative add-on transforms your Kreitler rollers into a powerhouse training machine, delivering a challenging, engaging, and realistic ride experience.

Contrary to what some might think, this unit won’t leave you spinning like a hamster or limit your power output. The resistance is so real and powerful, it could match Tadej Pogačar’s 7 watts per kilo with ease! Plus, it’s ideal for maintaining a smooth cadence while sparing your bike from undue stress caused by fixed rear-wheel trainers.

Easy to install, durable, and buttery smooth, the Killawatt is the ultimate pro-level upgrade for serious riders. Take your virtual training to the next level and make every pedal stroke count!

The chart is the power output at a 95 cadence with and without the KillaWatt. If you require more watts than this for longer than 90 seconds I'd recommend contacting a Pro Tour team.

Onward to winter

Recently installed on a Yelli Screamy to stud up for some winter riding. Feels great so far. The suspension fork I normally run is a Fox 34 29'er with 140mm. As I've installed a Rock Solid 490, I wish there was an option that matched my axle to crown more closely. 36mm with longer fork crown to not change my geometry....winky face....LOL.

works well

I'm using this for an old XC to gravel bike conversion. Much lighter than a suspension fork. Much more precise steering. Much less expensive than ENVE, Ritchey. Likely safer than an Aliexpress fork. Aluminum steerer is easy to trim. Very satisfied with performance.
