Rocksolid guarantee

Shop with confidence. If it’s not working out, you can return it (consumables, electronics, undergarments and swimwear excluded).
Really. If it's not up to snuff after you use it (a couple times) you can still bring it back. It lasts longer than 30 days, but not forever. We'll be fair about it.


A smart, direct-drive trainer that's quiet, easy to use and fully interactive with training apps. It also takes tire slippage and pressure calibration out of the equation. ANT+ and Bluetooth smart compatible, so it works with tablets, phones, computers and GPS headunits. With the ability to be controlled by a 3rd party training tool, you can set your intervals before getting on your bike and let the trainer do the resistance adjustments while you focus on goals.
