CeramicSpeed delivers unmatched performance in key areas of your bike.
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.
