CeramicSpeed OSPW Systems

As the fastest oversized pulley wheel system on the market, the CeramicSpeed Oversized Pulley Wheel System (OSPW System) has been developed to answer the riders’ increasing need for improved drivetrain performance.

The OSPW System optimises the overall efficiency of your drivetrain thanks to the extremely low friction of the CeramicSpeed Bearings and the unique design of the overall system.

Aero System

In a sport where marginal gains make the difference between victory and defeat, CeramicSpeed ​​has once again improved its OSPW for triathlon and time trial. In cooperation with the aerodynamics specialist from Formula 1, Simon Smart, the founder of Drag2Zero, who is also significantly involved in the development of the ENVE wheels, the OSPW Aero was developed in more than two years of detailed work.

By means of many, many wind tunnel tests, not only was the best cover found, but the entire shift cage was optimized to continue to ensure precise shifting and to keep the weight low despite the fairing.

In concrete terms: At an average speed of 35km/h, you gain seven seconds per hour with a conventional OSPW compared to the standard system, and a further 2 seconds with the Aero. That's 45 seconds more over an Ironman distance. If then the Hawaii qualification runs out or a new PB at the King of the Lake...

CeramicSpeed OSPW Compatibility

With more than ten unique OSPW Systems, CeramicSpeed covers most compatibilities for Shimano, SRAM and Campagnolo. One of the newest additions to the product range is the OSPW for SRAM Red/Force AXS. Compatibilities cover from Shimano 9100 to Campagnolo eTap and SRAM Eagle - and much more.

OSPW for both Road and MTB

The CeramicSpeed OSPW Systems are not only compatible with both road and off-road derailleur models, but also tested to improve performance in both disciplines. When riding road, the watt-saving and speed increase can help you save important seconds and minutes while the durability and longevity of the OSPW Systems come in play in the off-road disciplines.

OSPW for all rides

The CeramicSpeed OSPW, traditionally known for speed increase and road riding now covers all rides - from outdoor to indoor - and road to off-road. No matter if you want to improve your Avatar in indoor training, are racing to win or just riding with the friends outdoor, you will feel the true benefits of a CeramicSpeed OSPW upgrade.

Coated for even better performance

All CeramicSpeed OSPW Systems come in coated versions for even better performance. The CeramicSpeed coating os a thin metallic layer that covers the races of the bearings and provides even lower friction and longer lifetime.
