Looking for the ultimate upgrade your stock PF30 road bottom bracket for simplicity, incredible performance and ridiculous performance? Denmark's Ceramic Speed offers you a replacement that saves you watts and energy by reducing friction with every turn of your crankset. The science and testing behind the efficacy and benefits of ceramic bearings is definitive, but all ceramic bearings are not made the same. Ceramic Speed bearings are harder, perfectly round, and widely surpass the quality standards of most ceramics on the market. This is the Coated version. Coating is a metallic layer, which is 75% harder than the hardened steel races. The coating is applied in a very thin and even layer of 3 microns (0,003 mm) on the entire surface of the bearing race. Both the inside and the outside are treated to achieve optimal results- with 7.5 times the longevity of a basic grade 3 ceramic bearing equipped bottom bracket. Consider this- even if the bearing is contaminated with degreaser, water or mud, the risk of bearing failure due to corrosion is negligible.

The PF30 Ceramic Bottom Bracket is designed for frames with the 46mm internal diameter press-fit standard. It allows you to convert straight to road crank spindles that fit 68mm wide shells. The aluminum shell is machined to exacting tolerances, and no spacers are required for an ideal fit that is both efficient, stiff and quiet. Ceramic Speed's bearings ride in composite carriers and high-quality, steel races. The ceramic balls are polished to perfect smoothness, and should they make contact with a race, they won't damage it, but will actually serve to clean and eliminate any surface issues inside the race. Lubrication is specific to the Ceramic Speed system, as are the bearing seals. A syringe of the grease lubricant comes with the bottom bracket. Detailed instructions for installation and service come with the bottom bracket and can also be found on Ceramic Speed's Cycling website.

Properly installed, your bottom bracket should not creak or make noise. The crankset will spin freely, with the absolute minimum resistance. Machining and hand-assembly is done in Denmark, with each part and the final assembly thoroughly inspected before shipping to distributors. The 118 gram bottom bracket delivers performance far in excess of standard options on the market. Save watts and energy with every pedal stroke as you optimize your equipment to fully realize your human potential with the Ceramic Speed PF30 Ceramic Coated Bottom Bracket for SRAM GXP 24/22mm stepped or Shimano 24mm spindles.
