The eagerly anticipated external bottom bracket is now available, with two different bearing options. All common systems are covered with this upgrade unit - making it ideal for Shimano, Race Face 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 - a dedicated 83mm unit is also available. 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.
