A superb entry-level mountain bike that’s born for the trail.

The Calibre S2 feels as comfortable off-road as it does around town. With a trail-focussed geometry, it makes off-roading feel more fun and comes loaded with high-quality parts that you might not expect to find on an entry level bike. Quality hydraulic disc brakes give you all the stopping power you need to stay in control while the grippy off-road tyres and 100mm Calibre Suspension Fork absorb shock and help to smooth over the bumps as you ride.
