Rene Herse Bottom Bracket Shell, Standard
A bottom bracket shell specifically designed for wide tires. The chainstay sockets angle outward at a greater angle (10°) to accommodate curved chainstays. This provides extra tire clearance. It’s the secret for using wide tires with road cranks.
Designed for standard-diameter tubes and with enough material to carve and match your preferred lug shape, the Rene Herse bottom bracket shell combines light weight with versatility.
Made in Taiwan.
