These 17-tooth Oversized Pulley Wheels have been developed to accommodate the unique OSPW System, which has been tested and proven to deliver energy savings starting at 2.4 watts. Designed and produced in Denmark, these lightweight pulley wheels answer the riders’ increasing need for a more efficient drivetrain. As part of the OSPW System, your key benefits are less friction - as much as 60 % on the OSPW pulley wheels with coated bearings. Extra thin coating is applied on the bearing races and improves the lifetime of the bearings. The coating is 75% harder than hardened steel, which combined with the super smooth and round CeramicSpeed Balls, means virtually no wear on the bearing.
It is very important that you properly lubricate your pulley wheel bearings to benefit from the maximum performance and lifetime. When mounted on the OSPW System, add oil using the lubrication points found on the back cage plate to maintain your Oversized Pulley Wheel bearings. We recommend you do this whenever you lubricate your chain, after washing your bike, or after riding in wet or muddy conditions.
Please note these spare pulleys match soley for the CeramicSpeed OSPW System.
