Renthal R1 428 Spring Link

This is a Renthal R1 428 Spring Link, part number C253. It's a non-O-ring chain link designed to handle the tough demands of offroad riding. If you need a chain link that offers a good balance of strength, light weight, and efficient power transfer, this one is worth a look.

The side plates are made from shot-peened alloy steel, which gives them high-tensile strength and helps them resist impact loads. The inner links have a chamfered design to help prevent the chain from derailing, and the extended bushings are there to cut down on friction between the plates. Renthal also uses shot-peened solid rollers and chromized pins to help the chain last longer. The gold-anodized side plates are there to help prevent corrosion.
