CeramicSpeed
CeramicSpeed is a Danish company and the world leader in ceramic bearing technology for cycling. Founded in 2003, they produce ceramic ball bearings for every bearing in a bicycle — bottom brackets, wheel hubs, derailleur pulleys, and headsets — that offer measurably lower rolling resistance than steel bearings due to the ceramic balls' superior surface finish, hardness, and resistance to deformation under load. CeramicSpeed have published independent tests showing watt savings of 2–7 watts across a full drivetrain conversion — figures that matter in racing where races are decided by fractions of a second. What Does CeramicSpeed Make and How Much Faster Are They? Their Oversized Pulley Wheel System (OSPW) is their most iconic product — an aftermarket derailleur cage with 17-tooth ceramic-bearing pulleys that replaces the standard 11-tooth steel-bearing pulleys, reducing the angle the chain bends through the derailleur and dramatically cutting friction losses. Their UFO chain is a specially treated chain with friction-reducing surface treatment that requires no conventional lubricant — cleaned and retreated with UFO Drip rather than wet or dry lube. Why Invest in CeramicSpeed? CeramicSpeed is used by professional WorldTour teams and national teams at the Olympics because the watt savings are real and measurable. For amateur riders who already have good bikes and good legs, a CeramicSpeed bottom bracket or OSPW system is one of the most cost-effective performance gains availabl
