Renthal UltraLight Rear Chainwheels are CNC machined from 7075 T6 aluminum to extremely tight tolerances, 66% lighter than steel. Computer engineered and tested to ensure a precise fitment, concentricity and load dispersion with tooth profiling to provide maximum power transfer. A combination of high strength base material, cutting edge manufacturing methods and exceptional hardwearing surface treatments its clear to see why Renthal's light weight all aluminum rear sprockets can be found on the rear wheels of many factory race team machines.

The Renthal 478U-525-41P-HA UltraLight Rear Chainwheel is a CNC-machined rear sprocket made from 7075 T6 aluminum. Its lightweight aluminum construction is engineered to provide reduced weight compared with steel while maintaining the strength required for powersports applications.

Computer engineering and testing help provide precise fitment, concentricity, and load dispersion. The tooth profile is designed to support efficient power transfer, while the hardwearing surface treatment contributes to long-term durability. This rear sprocket uses a 525 chain size and has 41 teeth.
