Brother Cycles Kepler Frameset - Teal is Real

The Brother Cycles Kepler is the basis for a really great gravel or road bike. Classic good looks combined with modern geometry mean the frame can be built into anything from a fast commuter to a more relaxed road bike or a dedicated gravel bike. This versatility is the Kepler's greatest strength – a steel frame that feels just as natural on asphalt as it does on gravel and can be built in many different ways, depending on what you want to do with the bike.

This generation of the Kepler received several welcome updates. The lugged steel fork has internal routing for a dynamo cable and three mounting points on each fork leg. The frame has internal routing for the rear brake, an integrated seatpost clamp, a third bottle cage position under the downtube and a metal Brothers Oak Leaf badge on the head tube.

The frame is made from double-butted 4130 chromoly and ED-treated beneath the paint for better corrosion protection. The Kepler can be built with 700C wheels and tires up to 45 mm, or 650B with tires up to 48 mm. With narrower tires, you get a fast bike for the road and smooth gravel roads, while more tire volume provides better grip and comfort when the surface gets rougher.

There are mounts for racks and fenders front and rear, three bottle cage positions on the frame and extra mounting points on the fork. This makes the Kepler just as useful as a stripped-down gravel bike as it is as a fully equipped commuter or touring bike. The Teal is Real paint fades from teal to warm gray, giving the frame a much more personal look than a traditional single-color steel frame. If you want a Brother that's closer to road than the Mehteh, but still has room for proper gravel tires and luggage, the Kepler is the natural choice.
