The Uberbike BB386 Press Fit Bottom Bracket is designed for use with PF30 frames (46mm inside shell diameter / 86.5mm width bottom bracket shell) with a 30mm spindle diameter crank type. The bottom bracket is manufactured using 2 key materials, with the bearings housed in alloy cups for maximum bearing support and strength, which are then housed in a nylon shell to keep the bottom bracket quiet and creak-free in use. 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, and Hope cranks, as well as some models of Rotor and FSA cranks.
