Below are just a few of the main benefits of using an o-ring over a roller chain. What the one significant advantage of a roller chain has over an o-ring chain is its price.
Roller chains are much cheaper. And as a result, some riders feel the benefits provided by the o-ring chain are not worth the significant price increase. However, when you step back and compare the two types of chains, there are several reasons why an o-ring chain is worth the investment and might, in some cases, prove cheaper than roller chains.
For starters, standard roller chains have no built-in lubrication. Notify me of new posts by email. This site uses Akismet to reduce spam. Learn how your comment data is processed. Image source: dimecitycycles. Pros: 1. Cons: 1. Leave a Reply Cancel reply Comment.

X-ring technology was developed for the track and adapted for the street, where the better sealing of the X-ring helped increase chain life even more. As a track-bred product, X-ring chains are typically made from harder, stronger metals and may have weight-reducing features like hollow link pins and thinner side plates. With all those virtues, however, comes a higher price.
Sealing lube in around the critical wear components of the chain has taken what was already a practical, reliable and efficient drivetrain and made it even better. No wonder the majority of motorcycles rely on links and sprockets to get down the road. Great to see Ari back with a print magazine. I have always liked Rider, and now they and CW are the only 2 left. Pity that CW is just 4 per year. Good on ya Mark, Jenny, and Greg and the rest of the Rider gang.
Ari always does an excellent job with these type of informative articles. I hope to see more of his work in the print mag as well. So, with all this progress, why are we still using chains and sprockets to transfer all our fuel-injected, smile-creating power to the rear wheel? The answer is simple: because it works. These chains are comprised of more pieces than you may think, and they all rely on tight assembled tolerances to function properly.
ProX Racing Parts understands the importance of having high quality chain drive components. After all, a broken chain or sprocket means no riding, no performance, and no fun. Standard MX chains are comprised of inner links and outer links, assembled with pins, bushings, rollers, and plates. Outer links feature pins, which resemble needle bearings, that are press fit and riveted into chain plates via bushings that rest in the openings of the plates.
The pins of the outer links slide through the bushings and rollers of two inner links to meet the mating outer link plate. Repeat this assembly process, and you have your finished, linked chain. O-ring chains share the same anatomy as standard MX chains, with the addition of O-rings.
Each piece plays a critical role, because one failure of one part can snowball into a chain catastrophe. In ProX chains, the chain pins are surface-treated for a hardened outer material layer, increasing wear resistance without compromising the tensile strength of the inner material.
Rather, they are the acting component that allows the chain to bend smoothly around the sprockets without creating any binding or breakage from shock. ProX chain rollers are shot-peened, a process involving a metal surface being shot with small particles to better align the molecular structure of the metal, increasing strength and surface stress-resistance.
