Brother Cycles Kepler Frameset

Limited frames available

Designed 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.

Though we’re a bike shop that sells, builds and fixes bicycles, they’re really just the means to an end; albeit a beautifully designed means to an idyllic end. Our job most importantly is to encourage as many people as we can to get out and ride for transport and enjoyment. We'd love to make riding a bike as commonplace as your morning cup of coffee, which by the way is our other obsession.

Bicycle Junction is situated at 1 Marion St, Te Aro, Wellington.
