With the help of its unique design and ultra-low friction bearings, the Oversized Pulley Wheel System (OSPW) manages to optimize the overall efficiency of the drivetrain. The handmade system consisting of a shift cage and an upper and lower pulley reduces friction by 40 % compared to the standard setup.
In the version for Campagnolo 11-speed rear derailleurs, the OSPW system has an upper pulley with 13 teeth (guide pulley) and a lower pulley with 19 teeth (tension pulley) to ensure maximum efficiency.
For even greater durability, both derailleur pulleys are equipped with coated ceramic bearings. Their entire running surfaces are coated with an extremely thin (2-3 microns) protective layer, which is 75 % harder than hardened steel. This not only further reduces friction, but also makes the bearings less susceptible to contamination.
Compatibility:
rear derailleur:
cassette: 30 /32 teeth (max. pinion size)
Note: The installation of a cassette with 32 teeth is not possible with some Campagnolo rear derailleurs that do not have a B-Limit adjustment. This includes all EPS models.
Material:
derailleur pulleys: aluminium
ball bearings: ceramic
bearing races: stainless steel (hardened, coated)
shift cage: carbon fiber reinforced polyamide (PA)
CeramicSpeed coated products are covered by a lifetime warranty*. The unique coating formula 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 an 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 you choose the coated version.
* the lifetime warranty covers all coated bearings and OSPW derailleur cages of CeramicSpeed - and this even retroactively to all products purchased from 01.01.2021. The confidence in our own products should be passed on to the customers at this point. Products outside the new warranty terms will continue to be covered by a four-year warranty.
