|Description||The external bottom bracket is available with two different bearing options.
The machined aluminium cups hold full stainless steel cartridge bearings. 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 widths - with an 83mm width version and a specific road unit available.
Standard 6 colours are available on cups - red, blue,
silver, black, gold and gunsmoke, with the centre tubes being black.
