175RC Polypro 48 Pitch Pinion Gear.

The 175RC Polypro Hybrid 48 Pitch Pinion Gears feature a hybrid design that combines an aluminum center hub with a non slip molded Polymer Gear. The molded tooth profile is much smoother than a typical machined metal gear and provides a quieter and smoother running gear train. Plus, the lightweight of the hybrid design has been proven to increase acceleration off the line and out of the corners, as well as improve the overall feel of the power delivery and efficiency when compared to heavier standard pinion gears.
