The Kepler has been a stalwart in the Brother Cycles lineup for 7 years now and keeps going strong into 2022. They designed the Kepler with versatility in mind, it’s a gravel grinder, super commuter, galactic tourer... ready to tackle whatever you throw at it. So if you need a bike that's as happy on the daily commute as it is on a weekend bikepacking trip, look no further than the Kepler.
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 2019 a Kepler placed 3rd in the inaugural GBDURO bikepacking endurance race - a 2,000km mixed terrain race from Land's End to John O'Groats in the UK.
