Rene Herse Bottom Bracket Shell Oversized
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 oversized tubes and with enough material to carve and match your preferred lug shape, the Rene Herse bottom bracket shell combines light weight with versatility.
