The ONER eccentric bottom bracket is designed for converting PF30 frames to single speed. The ONER has 12mm of adjustment, allowing for multiple cogs sizes to be used with the same chain length.
Compatible with any 30mm/DUB spindle crankset that can accommodate 20mm (10mm per side) outboard bottom brackets.
