What is the difference between the Omnium Over-Drive and the Zero Drive?

The Over-Drive offers hands-free, internal progressive resistance and is often used for training or a hard workout. It gets harder to pedal the faster your rear wheel goes. By contrast, the Omnium Zero Drive does not produce any resistance and is used most often for a portable warm-up when you simply need to practice free-spinning, fast leg speed, like for track racing.

How do I fit my larger mountain bike on the Omnium?

If your bike does not fit the original Omnium, you will need the Omnium Trainer Sled Extension, which supports bikes in larger sizes.

How do I change the resistance on the Omnium Over-Drive?

Just pedal! The Omnium’s interval progressive resistance means that the faster your rear wheel spins, the more resistance you get.

Can I connect my Omnium with a bike training app?

To connect your Omnium with a training app, you will need a rear wheel sensor or power meter connected to a bike computer or an app. Some apps have a built-in Omnium power curve to estimate power produced when using the trainer. 

Can I use the Omnium with knobby tires? 

You can use the Omnium with tires that have knobs, but expect more noise than you would using a traditional road or training tire. 

How to change the wheelbase length?

You can use the z-knobs on the wheelbase slider to change the length of your trainer for different bikes. 

What is the resistance curve on the Omnium Over-Drive?

The resistance curve can be found here.

Does this come with a bag?

Yes! The Omnium comes with a protective travel bag.

Why is the Omnium Over Drive more expensive than the Zero Drive?

The Over Drive has a complex internal structure that includes powerful magnets to create an electromagnetic eddy current, which generates progressive resistance inside the drums as they turn faster. The materials, construction, and calibration of the drums is more expensive to produce.
