Brother Cycles all-purpose, all-road steel frameset – the Kepler has been a stalwart in our lineup for 5 years now. It has been designed with versatility in mind, so whether you’re planning a weekend bike-packing trip, thrashing some gravel trails or even a full blown transcontinental tour – the Kepler can handle it.
The 2019 Kepler has increased clearance for 700x45c or 650x48c tyres – for when the going gets tough. 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. The double butted chromoly tubing makes for a tough yet responsive ride which will keep going for years to come.
