This Uberbike Press Fit Bottom Bracket is designed for use with frames that feature a 41mm inside shell diameter with a 28.99mm SRAM DUB spindle diameter crank. 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.
