Fully developed, designed and manufactured by CeramicSpeed in Denmark, the Oversized Pulley Wheel System for SRAM Road is a technological advance for the bicycle industry.
The OSPW system for SRAM rear derailleurs is compatible up to a cassette format of 32 teeth and can be used with both short cages and WiFli rear derailleurs. The product is for the SRAM 10 / 11-speed and is not compatible with the 12-speed SRAM eTap AXS.
The total power saving of the OSPW system for SRAM is 40% - 60%, in some cases more. The oversized shift rollers have a 3-5 times longer service life than the standard rollers available on the market.
