Kepler

£439.00 £329.25

The Kepler is designed to take on whatever challenge is thrown at it, whether that’s thrashing along forest rails, taking it on a weekend bikepacking trip or even a full blown transcontinental tour.

Based on cyclocross geometry, the Kepler can run fatter tyres when you need them or slicks when you want to keep up with the roadies. And of course it’s fully equipped to fit front and rear panniers if you’re loading up for a longer trip. The double butted Cr-mo tubing makes for a tough yet lightweight ride, which should keep going for years to come.
