Cross-country tyres
Ultra-fast-rolling cross-country bike tyres are built around a tread design that strikes a balance of rolling speed and traction and are ready to dominate the race course or crush the driest, dustiest trails.

Go tubeless
Maximise performance and minimise flats when you set your tyres up tubeless.
Wider tyres, less pressure
Remember to adjust tyre pressure as you adjust tyre width. Personal preference plays a large role here, but wider tyres tend to have more overall volume and perform better at slightly lower pressures.
Be confident in your decision
There are a lot of options out there, but by taking it one step at a time, starting with tread, then considering construction and finishing at tyre size, you will find the right tyre for you. Luckily, you don’t need to worry much about making the wrong decision thanks to our Unconditional Bontrager Guarantee.
