Direct replacement for Campagnolo Ultra-Torque bottom brackets and most Shimano HT2 bottom brackets (for use with existing plastic sleeves).

Ceramic hybrid bearings have a conventional steel outer race but with ceramic balls inside. The harder ceramic balls roll a little easier, weigh a little less and the bearings have been designed to minimise rolling friction.

These bearings are not recommended for mountainbiking applications as they are virutally unsealed and only suitable for dry conditions.
