The Kepler was designed with versatility in mind, it’s a gravel grinder, super commuter, galactic tourer - ready to tackle whatever you throw at it.

Look no further than the Kepler if you need a bike that’s as happy on the daily commute as it is on a weekend bikepacking trip.

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. It features laser cut disc dropouts with a replaceable derailleur hanger, s-shaped chainstays and a unicrown steel fork.
