Hope Bottom Bracket Cups Stainless Steel PF46-68/73/83-24

High-quality, CNC machined aluminium external bottom bracket cups with double sealed stainless steel bearings. All common systems are covered with this upgrade unit - making it ideal for Shimano, Race Face, FSA and other cranksets.

The machined aluminium cups hold full stainless steel cartridge bearings in stainless races. These custom made bearings are double sealed and fully serviceable to offer a much greater life span than stock units. If they wear out eventually, they are replaceable. The bearings are made by INA and have been designed to run directly on the crank spindle, without the use of shims or spacers - again increasing life and reliability. Hope uses a non contact, free running labyrinth seal to protect the bearing externally, and the machined aluminium center tube is sealed internally with o-rings.

The Hope PF46 - 68 - 24 unit is suitable for road bikes with 68 mm case width. The PF46 - 73 - 24 and PF46 - 83 - 24 version are suitable for mountainbikes with 73 and 83 mm case widths.
