Hope External Bottom Bracket - Ceramic


Hope External BB - Ceramic Bearing MTB Red

At last - a bottom bracket designed for the UK! Runs on sealed ceramic replaceable cartridge bearings, with external non-contact labyrinth seals, and internal o-ring sealed alloy cups - for years of maintenance free use. Also available with stainless balls/stainless races.

Hope say :-

The external bottom bracket is available with two different bearing options. All common systems are covered with this upgrade unit - making it ideal for Shimano, Race Face, FSA and others. The machined aluminium cups hold either full stainless steel cartridge bearings, or ceramic bearings in stainless races. These custom, Swiss made bearings are double sealed, fully serviceable and removable which give much greater life span than stock units. The bearings are made (as all our bearings are) by INA and have been designed to run directly on the crankset axle, without the use of shims or spacers - again increasing life and reliability. We use a non contact, free running labyrinth seal to protect the bearing externally, and the machined aluminium centre tube is sealed internally with o-rings. The unit is suitable for 68 & 73mm shell width’s - with an 83mm width version and a specific road unit to follow later in the year.. Standard 6 colours are available on cups - red, blue, silver, black, gold and gunmetal, with the centre tubes being black on the stainless and gunsmoke on the ceramic. The ceramic weighs 109g and the stainless 113g
