Shimano GRX 400 10 speed

Designed for riding on paved and unpaved roads with drops of less than 15 cm

If you’re like us, you love riding in rough terrain but live in a more urban jungle. So you need a bike that is fast on-road and capable off-road.

The Ultra is our most extreme bike, starting out the design process with 55-61mm wide tires. We then designed the whole aero package around those to keep the on-road speed high. If you ride on less extreme terrain, you can also fit 700c tires up to 45mm WAM (With As Measured) on the Ultra.

If you’re looking for a bike that is even further optimized for speed with narrower tires (35-46mm WAM), then the Exploro RaceMax is your perfect match.
