The PressFit46/24mm bottom bracket allows you to use a chain-sets with 24mm axles in Pressfit30 frames making it ideal for Shimano, Race Face and others. The machined aluminium cups holds ceramic cartridge 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 Hope 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.
Hope 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 and 83mm shell width's.
Bicycle bottom brackets connect the cranks to the bike and allow the crank arms to rotate. There are various sizes of bottom bracket shell on the market, so compatibility needs to be checked. The three most common frame bottom bracket shell widths are 68mm (English threaded road and mtb), 70mm (Italian threaded road) and 73mm (British threaded mtb). There are also many axle shapes and styles, from JIS or ISO square tapers through to the round splined axles such as ISIS or Octalink and then there is the new external cup systems which have the axle built into the crank arms. Some frames are now using the new BB30 system which uses bearings pushed directly into the frame and removes the needs for cups to be threaded into the frame.
