Custom bearings with high performance seals, the e13 bottom brackets offer very good durability and are availability to suit almost any configuration. Even if you have a tricky setup like a 30mm spindle crankset and a BSA threaded frame - you can still run your crankset and get the benefits of the threaded frame.
The PressFit system uses a thread-together system that offer precision alignment, ease of install and creak free pedalling.
Race and Plus cranks have a 30mm spindle and the Base cranks have 24mm spindles
