SRAM 9 and 10 speed
Designed to fit all SRAM 9/10s derailleurs, these CeramicSpeed Pulley Wheels put less friction between the power transferred from your legs and the rear wheel. Each pulley wheel is fitted with CeramicSpeed high quality bearings that offer for a more efficient drivetrain.
Aluminium Pulley Wheels
Better than the standards equipment, these pulley wheels feature aluminium alloy pulley wheels that are extremely light, weighing only 22g, without spacers. Low friction and long lifetime is the essential and unique mix of properties that makes these pulley wheels superior to the market’s standards.
Note: these Pulley Wheels are not delivered with spacers. When mounting the pulley wheels reuse the original SRAM spacers.Mounting and Maintenance
