Renthal 441U-428-49GPSI 49-Tooth Rear Chainwheel

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 441U-428-49GPSI UltraLight rear chainwheel is a CNC-machined powersports sprocket made from 7075-T6 aluminum. Its lightweight aluminum construction is designed to provide reduced weight compared with steel while maintaining the strength required for powersports use.

Computer-engineered and tested for precise fitment, concentricity, and load dispersion, the chainwheel features tooth profiling intended to support efficient power transfer. A hardwearing surface treatment helps protect the sprocket during use. Manufacturer part number: 441U-428-49GPSI. Vendor part number: 441U-428-49GPSI.
