The Uberbike BSA compatible bottom brackets have been specifically designed for use with either 68mm or 73mm BSA threaded MTB or Road bottom bracket frame types using a 30mm spindle diameter chainsets. The bottom bracket cups are CNC machined from lightweight but strong 6061 alloy. For bearings, we have selected to use carbon steel over standard chrome steel bearings for their superior hardness and increased load capacity, offering a higher life cycle which makes them an ideal choice for mountain and road bike bottom brackets, with the 2 rubber seals acting as a barrier to help lock out dirt and ingress, whilst keeping the lubrication trapped inside.

Chainsets that use 30mm diameter bottom brackets include SRAM with their BB30/PF30 cranks, Raceface Cinch cranks, Hope cranks, as well as some models of Rotor and FSA cranks.
