Setup, Compatibility & Care
Installation of the 9011063 pulley involves securing the assembly to the rear frame mount. Ensure that the cable housing is seated firmly within the pulley groove to prevent binding. When threading the gear cable, ensure there is no fraying, as this will catch on the pulley wheel. Compatibility is limited to Brompton bicycles utilizing internal hub gear setups; verify your specific model's gear configuration before attempting installation. For care, keep the pulley wheel lubricated with a light bicycle-grade lubricant and periodically check for lateral play in the pulley arm, which can indicate that the bolt requires tightening or that the assembly is nearing the end of its service life.
