The Kepler has been a stalwart in our lineup for nearly a decade and has recently undergone some exciting design changes. The much-loved Kepler geometry remains, however, we’ve made some functional and cosmetic changes to bring the product in-line with what we’re looking for from a versatile steel frame such as the Kepler. These changes include:

– All new lugged steel fork with dynamo routing
– Internal cable routing for rear brake
– Brazed seat collar
– Bottle mounts on the down tube
– New Oak Leaf metal head badge

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 Kepler features triple cage mounts on each fork blade.

In the 10 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 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 in style and with a smile on your face.
