Description
CeramicSpeed OSPW pulley system SRAM eTap – increased performance, saved energy
The CeramicSpeed OSPW pulley system for SRAM eTap® helps you upgrade your drivetrain to improve performance. Its two oversized 17-tooth jockey wheels (available in black or red) have very efficient and smooth-running ceramic bearings. There is also a weight-saving yet robust polyamide-carbon cage. This model is compatible with electronic 11-speed eTap gears. Like all Oversized Pulley Wheel (OSPW) systems from CeramicSpeed, the SRAM version also offers less friction compared to standard pulley wheels and enables significant energy savings.

Ceramic bearings from CeramicSpeed
CeramicSpeed ceramic balls are rounder, harder, smoother, lighter and more resilient than steel balls and ceramic balls from other manufacturers. CeramicSpeed ceramic bearings therefore last 3 to 5 times longer than other bearings on the market. All CeramicSpeed bearings are hand-made in Denmark under clean room conditions and subject to a strict four-stage control process. Among other things, the size of the ceramic balls is checked to the thousandth of a millimeter. Tests are then carried out in the laboratory or, preferably, by professionals in training and competition. CeramicSpeed bottom brackets guarantee you the lowest possible friction, optimized power transfer and maximum durability and also help you save watts and reach the finish line faster. It's not about seconds, it's about minutes!
OSPW
The Oversized Pulley Wheel System (OSPW System) is a groundbreaking innovation from CeramicSpeed, developed in collaboration with world-class triathletes. This unique system provides 40 - 60% less friction compared to standard jockey wheels and enables power savings of at least 1.6 and up to 2.4 watts. The OSPW system features the unique CeramicSpeed bearings, aluminum jockey wheels and a polyamide-carbon cage, which makes it 3 to 5 times more durable than standard systems on the market. A true advancement in the field of cycling performance.
Manufacturer's note: Before transporting the bike in a travel bag, the rear derailleur should be completely dismantled, otherwise the OSPW system could be damaged.
