Developed, engineered and manufactured entirely in Denmark by CeramicSpeed, the Oversized Pulley Wheel System (OSPW) is a technological advance for the bicycle industry. Combining the highest quality materials with a unique design, the OSPW system offers lower friction and longer life, enhancing your competitive edge.
Thanks to the OSPW system, energy savings start at 40% and the CeramicSpeed bearing inside ensures 3-5 times longer life. Wattage savings with a CeramicSpeed OSPW system start at around 1.6 watts and higher.
CeramicSpeed coated bearings
CeramicSpeed coated products are backed by a lifetime warranty*. The unique formula of the coating is a metallic layer that covers the bearing races and makes them 75% harder than steel. Thanks to this, they are highly resistant to corrosion and the coating provides even lower friction than our standard bearings. Even if the bearing is contaminated with degreaser, water or mud, the risk of bearing failure due to corrosion is negligible if the coated version is chosen.
*lifetime warranty covers all CeramicSpeed OSPW coated bearings and rear derailleur cages, including retroactively for all products purchased on or after 01.01.2021. At this point, the trust in our products should be passed on to customers. Products that do not fall under the new warranty conditions will continue to be covered by a four-year warranty.

Only fits SRAM eTap rear derailleurs.
