When every detail matters.
Reducing drivetrain drag might not always be the first step in going fast, like improving aerodynamics, but unlike cheating the wind where the faster you go, the resistance is magnified, drivetrain friction is detrimental at every speed. So whether that’s a 5 MPH climb up double-digit grades or going for a TT PR on a flat 40K course, anything you can do to reduce losses from drivetrain friction will pay dividends. Enter CeramicSpeed's Limited Edition Pink Oversized Pulley Wheel System offering a one-two punch against drivetrain friction by using larger diameter aluminum pulleys to help reduce the angle of the chain's articulation, and it fits them with those famous high-quality CeramicSpeed bearings that spin effortlessly, all the while paying homage to the Giro and several of its sponsored teams competing there.
The remarkable cage and pulley systems are developed and hand assembled in Denmark. The products are all tested in the lab and with feedback from professional riders and mechanics to ensure it works great in the field and installs easily. CeramicSpeed claims the OSPW System is the fastest pulley system in the world providing an energy savings of around 1.6 watts for SRAM and 2.4 watts for Shimano over their standard pulleys. As a bonus, CeramicSpeed's testing shows that these pulleys last anywhere from 3-5 times longer than stock.
We have models for Shimano, Campagnolo, and SRAM eTap rear derailleurs. The OSPW System for SRAM features two 17-tooth aluminum pulley wheels with the accommodating cage made from nylon and carbon fiber and can fit cassettes up to 32 teeth. For Campy riders, the system uses a 13-tooth top and a 19-tooth bottom and provides a claimed 40% reduction in friction over the standard 11-tooth Campagnolo pulley wheels. It too can fit up to a 32-tooth cassette and is compatible with all Campagnolo electronic rear derailleur (EPS) and all mechanical rear derailleurs utilizing a mounting sleeve. The OSPW System we have for Shimano is compatible with 11-speed Ultegra 8000/8050 and Dura-Ace 9100/9150 electric and mechanical groupsets except for the R8000 GS. It features an optimized 13/19-tooth combination developed to fit the design of the derailleur and up to a 32-tooth cassette.
