The UltraLight sprockets from Renthal are CNC machined in Manchester, UK, from 7075 T6 aluminium with extremely tight tolerances, making them 66% lighter than steel. They are designed and tested on computers to ensure a precise fit, concentricity, and load distribution, with tooth profiling for maximum power transfer.
Thanks to a combination of very strong base materials, advanced manufacturing methods, and exceptional wear-resistant surface treatments, it's clear that the lightweight aluminium sprockets from Renthal are found on the wheels of more racing teams' machines than all other competing brands combined.
