The fastest oversized pulley wheel system in the world is also available for SRAM Rival & Force 1 Type 3 derailleurs.
Featuring 14-tooth (upper) and 18-tooth (lower) pulleys with a narrow-wide profile, the OSPW X System for SRAM 1x is available fitted with CeramicSpeed standard or coated bearings, with up to 6 years of warranty. The unique narrow-wide tooth profile of the pulleys ensures durable chain retention.
The system is fitted with a custom designed, strong carbon fiber pulley cage assembly for long durability and light weight. The cage design allows you to choose between two spring tension settings to customise performance and reduce chain drag. We recommend initial setup in the lower spring tension. This has been designed to leave the clutch mechanism fully functional for chain retention.
In the event that the low spring tension does not provide adequate shift quality on real rough roads, you can increase it to the high spring tension which corresponds to the factory settings.
Thanks to the high-quality CeramicSpeed Bearings inside, your product will benefit from 3-5 times longer lifetime compared to stock.
The OSPW X System for SRAM 1x has been tested to deliver 30-40% less friction than conventional systems.
Together with the top quality CeramicSpeed Bearings inside, the product is completely developed and handbuilt in Denmark.
SRAM Force 1X 11 speed with Type 3 clutch and cage lock position 8 o’clock* (see Tech Data tab for more info)
SRAM Rival 1X 11 speed with Type 3 clutch and cage lock position 8 o’clock* (see Tech Data tab for more info)
The OSPW X cage fits all Rival & Force1 derailleurs with Type 3 clutch regardless of the cage length. The cage lock position needs to be in the 8 o’clock position (not 5 o’clock) for complete functionality.
The cage is NOT compatible with Type 2.1 clutch.
Note: Only install this product on derailleurs with an 8 o’clock cage lock position. It will not fit derailleurs with a 5 o’clock cage lock position.

• Adjustment of spring tension can allow for customization of user experience. Higher spring tension can focus on chain rentention & crisp shift response. Lower spring tension will reduce chain drag and improve overall efficency.
• The CeramicSpeed OSPW cage design has been tested for aerodynamic impacts in multiple wind tunnels. No measurable adverse aerodynamic impacts were measured through a variety of yaw angles.
• Shimano Ultegra R8000 GS, R8050 GS, and 105 derailleurs are not compatible with any CeramicSpeed OSPW system.
• SRAM Rival, & SRAM Apex derailleurs are not compatible with any CeramicSpeed OSPW system.
