This is an updated version of the Oversized Pulley Wheel System for Shimano 9100/9150 and 8000 SS/8050 SS. This new design has an integrated stop tower for easier mounting.
The CeramicSpeed Oversized Pulley Wheels System has been proven to be the fastest pulley system in the world, providing energy savings starting at 2.4 watts compared to standard Shimano systems.
The OSPW System for Shimano 9100/9150 and 8000 SS/8050 SS is an industry-leading product, chosen by many of the world's leading cycling teams and professional triathletes.
It features a 13-tooth upper pulley wheel and a 19-tooth lower to provide absolute optimization of the rear derailleur, and these oversized aluminum pulley wheels come fitted with either standard or coated CeramicSpeed Bearings: your choice.
The Shimano 9100/8000 OSPW system is compatible up to a 32 tooth cassette for both Dura Ace & Ultegra derailleurs
The typical overall power savings of the OSPW System for Shimano 9100/9150/8000 is 30%-60% over a stock setup.
The oversized pulley wheels have lifespan that is 3-5 times longer than the commonly used standard pulleys on the market.

SRAM's 1x Eagle component system boasts a twelve-speed cassette. We built pulleys that can handle the load better than stock. These CeramicSpeed Pulley Wheels work with less drag, adding to the power transmitted to the rear wheel while offering greater durability, going longer between replacement intervals.
These pulleys are also fully compatible with the SRAM Eagle AXS derailleur.
The aluminum pulleys with standard bearings are 34.4% more efficient than stock and use our low-drag, long-life Standard Bearing with hardened-steel races and our super-round CeramicSpeed balls. The upper and lower pulleys both have a narrow-wide tooth design with 14 teeth each. As the upper and lower pulleys have different tasks, they have different shapes. You'll find they are thus marked, and have directional arrows.
These pulleys should be installed with stock SRAM pulley spacers. Save those from your old pulleys before installing CeramicSpeed.
The kits come with CeramicSpeed Oil in a 15ml dropper bottle and grease in 5ml syringe. The bearings come pre-oiled. The grease can be used on the pulley bearings when riding in particularly harsh environments.
In the box:
- 2 x 14-tooth pulley wheels
- CeramicSpeed Bearing Oil in 15ml dropper bottle
- CeramicSpeed Grease in 5ml syringe
- Sticker sheet

Increase the performance of Rockshox forks with a Charger upgrade kit. Features include a no compromise lockout, where the "Pedal" and "Lock" circuits sit behind the damping, meaning no sacrifice in downhill bump control while maintaining pedaling stability on climbs. The extruded bladder design is durable, resists damping change during extended downhills and has virtually zero pressure offset for small bump sensitivity. Available damper settings: Open with an adjustable low speed compression, Pedal and Lock.
- Extruded bladder design is durable, resists damping change during extended downhill runs and has virtually zero pressure offset for small bump sensitivity
