You've been pouring it all into your training and you can't afford any wasted effort on sub-standard products that won't let you perform at your best. The SRAM PF30 Ceramic Bottom Bracket is the same one that top-level athletes race on. It uses ABEC-1 rated bearings and advanced, low-friction seals to ensure the PF30 Ceramic Bottom Bracket gives nothing to friction.
Silicon nitride ceramic ball bearings offer greater roundness and superior hardness compared to stainless steel alternatives. This substantially reduces mechanical drag. After aerodynamic drag, mechanical drag is the leading culprit in consuming the power you put into the pedals. Ensuring the reduction of drag is good for the long haul is the Gutter Seal Technology.
Gutter Seal Technology uses a unique seal design to drastically improve protection against water and dirt contamination without adding any additional drag. This boosts the bearing life and keeps downtime to a minimum. Nylon cups are pressed into the frame's bottom bracket shell which needs to be 68mm wide for this road version. This setup is extremely lightweight and offers a narrow Q-factor to boost ankle clearance, which allows for enhanced crank and frame designs.
The SRAM Ceramic PF30 Bottom Bracket is compatible with all SRAM cranksets and other cranks with a 30mm-spindle.
