Our entire Kepler shipment has already sold out on pre-order! Apologies to any customers who missed out on getting one. The next shipment will be with us in early 2021.

The Kepler has been a stalwart in our lineup for 6 years now and keeps going strong into 2021. 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. 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 700x45c or 650x48c 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. For 2021 the new Kepler now features flat mount thru axle dropouts with a replaceable derailleur hanger, s-shaped chainstays and a 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.

Carbon Fork Upgrade: At checkout you may upgrade your fork from steel to carbon/alloy for £50. You can check the spec of the carbon fork here
