The Uberbike Shimano Hollowtech 2 and Raceface X-Type compatible bottom brackets have been specifically designed for use with either 68mm or 73mm BSA threaded MTB or Road bottom bracket frame types using 24mm spindle diameter chainsets. The bottom bracket cups are CNC machined from lightweight but strong 6061 alloy and are available in a range of 8 anodised finish options. 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 24mm diameter bottom brackets include Shimano Hollowtech II, as well as some models of Raceface, FSA, and Rotor.
