Brother Cycles Stroma Black - Frameset

Brother Cycles Stroma is a Frames for anyone looking for a fast road bike that works year-round. It has clear road geometry, but with room for wider tyres, disc brakes and mounts for mudguards and a rack, Stroma handles much more than fine summer days on perfect asphalt. Our advice is much the same as before: ignore the weather gods and ride anyway.

The frame combines a heat-treated Reynolds 725 main triangle with a shaped Reynolds 520/500 rear triangle and Brothers' carbon fork. Tyre clearance is up to 700 × 38 mm, or 32 mm with full-length mudguards, allowing for more comfort and grip on poor asphalt and lighter gravel. Thru-axles, flat-mount disc brakes and internal routing for a dynamo cable through the fork provide a modern foundation for the build.

Stroma is Brothers' more road-oriented option - fast and responsive rather than a gravel bike built around really large tyres and lots of luggage. With mounts for rear mudguards and a rack, two bottle cages and the option of internal cable routing for a rear dynamo light, it can still be built into an unusually versatile road bike for commuting, long rides and year-round cycling.
