Brother Cycles Kepler Frameset

One frame. Endless adventures.

The Kepler has been Brother’s all-rounder workhorse for nearly a decade—and it just got even better. With updated features like a new lugged steel fork with dynamo routing, internal brake cable routing, and a stunning oak leaf metal head badge, the Kepler continues to deliver unmatched versatility for touring, commuting, and off-road exploration.

It runs 700c or 650b wheels, fits up to 700x45c or 650x48c tyres, and comes fully equipped with rack, fender, and triple bottle mounts. Whether you’re bikepacking across continents or riding to the corner shop, the Kepler is ready.
