Claud Butler Alpina 1.0 2026 Bike

The Claud Butler Alpina range has been completely overhauled, with two models, a new frame, modern trail riding geometry and the latest in Shimano CUES - Claud Butler's vision for the Alpina was to create a bike that thrives exploring UK trails.

The Claud Butler Alpina 1.0 is Claud Butler's introductory model to the all-new Alpina range - designed to help you cover anything from the many miles of canal towpath right through to the thrill of off-road trail riding.

Using Shimano’s latest CUES series drivetrain components, the 2x9 drivetrain offers all the gears you could need with a 22-36T chainset and 11-36T cassette. Claud Butler have also stayed with Shimano for the brakes, using their ever-reliable MT200 hydraulic disc brakes that offer consistent and reliable stopping power.

The Alpina was always about developing a mountain bike that could handle the demands of UK trail centres and off-piste wild tracks, and central to that is modern-thinking frame geometry, specifically built around a 100mm fork and 29in wheels. Longer top tubes and slacker head angles combined with super short 45mm stems and ultra-wide 750mm handlebars result in a confidence inspiring ride that feels controlled while you enjoy the thrill of the trail. Adding to this, we’ve used 29 x 2.25" WTB Ranger tyres that are known for their fast-rolling, good puncture resistance and good grip across a range of trail conditions.

All in, the Alpina 1.0 is a diverse bike suited to a variety of riding environments and is ready to tackle whatever you can throw at it.
