Featuring a colorway giving an honorable nod to the 3Rensho Katana, this latest iteration of the Rush has more tire clearance than previous models, but its swift geometry and stiff chassis are still most in its element on chewed up asphalt or the velodrome.

An expertly butted Tange Prestige chromoly tubeset with side-tacked seatstays and S-bend chainstays offer a smooth stylish ride. To cap off its Keirin-inspired look, the Rush is paired with a flat-crown threaded fork for clean, timeless look.

If you're running brakes, a 57mm reach (mid-reach) caliper is required.

ⓘ Due to slight sizing and geometry revisions to allow increased tire clearance, size 48cm fits more like a 51cm than a true 48cm. Please check the geometry chart!

Frame preparation info

Proper preparation of a new frame is an essential part of building up any new bike.

This process typically involves facing and chasing the bottom bracket shell to clean the threads and remove any paint, clearcoat overspray, or internal frame coating buildup before installing a bottom bracket, as well as facing and reaming the head tube to remove any imperfections prior to headset installation.

These procedures require specialized tools, and can be performed by any reputable bike shop in your area.
