Hope MTB Bottom Bracket Cups Ceramic - Silver
High-quality, CNC machined aluminium external bottom bracket cups with double sealed ceramic bearings. All common systems are covered with this upgrade unit - making it ideal for Shimano, Race Face, FSA and others.
The machined aluminium cups hold full ceramic 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 unit is suitable for 68 and 73mm shell widths. Different anodized colours are available on cups.
