OMNI Racer Lightweight Ti Ceramic Hollowtech II Crankset Bottom Bracket Fits All Shimano Hollowtech II Cranksets: Dura-Ace, Ultegra, 105, XTR, XT, and More: JUST 74g

CERAMIC BEARINGS = INCREASED SPEED PRODUCT FEATURES: LIGHTWEIGHT DESIGN: Combination of the lightest materials and construction make for the LIGHTEST integrated bottom bracket made. SUPER SMOOTH TiN CERAMIC BEARINGS: Nano-technology Titanium Nitride (TiN) coated ABEC 5 Grade bearing races with Si3N4 Grade 3 ceramic balls. Lighter stiffer & smoother and will last longer than other ceramic and steel bearings Performance Breakthrough - Speed increases approaching 4%, i.e., over 1 km a rider can gain 20-40m TiN nano-technology surface treatments fill stainless steel pores making the bearing races smoother, harder, and more durable than standard stainless races. 60% lighter than steel bearings Produce up to 60% less friction 15-20% stiffer than steel ones Extremely resistant to corrosion Lifetime 10 times longer than steel bearings SUPER LOW FRICTION X-SEALS: Patented technology uses Low Friction Dual Lip Seals housed in the TiN bearings and CNC machined alloy cups. This allows the seals to fit very precisely and allow for less contact between the rotating parts in order to reduce energy-wasting friction. In addition, the seals provide better protection for the bearings since there is less space for the elements to get past the seals SUPER LIGHTWEIGHT CNC ALLOY CUPS: CNC machined durable forged aluminum alloy cups hold bearings tight. DURABLE ANODIZED FINISH: Beautiful anodized color options prevent alloy corrosion increasing bottom bracket life. LIGHTWEIGHT POLY BEARING DUST COVER: Provides another level of protection to bearing X-Seals. Made to fit precisely over bearings. LIGHTWEIGHT BODY: Poly body for reduced weight. Is optional to use.
