The Kepler has been a stalwart in our lineup for 8 years now and keeps going strong into 2023. We designed the Kepler with versatility in mind, it’s a gravel grinder, super commuter, galactic tourer… ready to tackle whatever you throw at it.

The Kepler can run either 700c or 650b wheels and has clearance for 700c x 45 or 650b x 48 tyres to keep you stable when the going gets tough. The frame is constructed from double butted 4130 chromoly steel, a functional tubing which provides the perfect balance of comfort and durability and we’ve applied an ED coating under the paint to protect against corrosion. It’s fully equipped to fit front and rear racks, mudguards and has three bottle mount positions if you’re loading up for a longer trip. To add to its bikepacking credentials the 2022 Kepler now features triple cage mounts on its unicrown steel fork.

In the 8 years since it’s launch, we’ve sent Keplers to every corner of the globe, from the Australian outback to the hills of California, up up to the Highlands of Scotland and along the coastal trails of Dorset. Whether taking part in a multi-day bikepacking race or simply tackling the daily commute, the Kepler gets you there with a smile on your face.
