Drive Line Review: Renthal R3-2 O-Ring Chain

Why The Renthal R3-2 O-Ring Chain Is King Of The Hill

Exclusively designed for heavy-duty racing applications, the Renthal R3-2 O-ring chain is made for the intense rigors of off-road applications. The chain is lightweight, low friction, and offers high performance that offers the winning edge. It’s 5 percent lighter and has a pin diameter that is 3% bigger compared to the previous model. This chain provides the highest impact resistance, wear resistance, and tensile strength that you can find on the market.

Many Riders prefer O-ring chains, and the Renthal R3-2 doesn’t disappoint. The R3-2 has alloy steel side plates to provide the highest force load resistance and tensile power that you should expect from a chain. The unique vacuum grease injected inside the chain joint prolongs the chain’s life.

The R3-2 has an average tensile strength of 8100 lbs and is pre-stretched to enhance chain performance, thus offering a smooth ride all the time with minimal adjustment. Its alloy steel bearing pins also provide excellent resistance to daily wear and tear. Since it’s easy to install, you can use it right away when you need it and remove it anytime you want.

Its friction drag is relatively small, and since it requires very little maintenance, you don’t have to worry about spending money to maintain its good condition. The chain also features side plates that are gold plated that help prevents rust, prolonging the service life. The Renthal R3-2 comes with two master links – 1 with the standard clip and 1 with a rivet. All you have to do to maintain its performance is to keep it clean and lubricated.

Renthal R3-2 O-Ring Chain Features

• Alloy steel side plates (shot-peened) offer maximum blow load resistance and high tensile power
• Side plates that are plated gold help prevent rust
• Nitrile O-rings lengthen chain life by keeping patented vacuum-injected grease within the chain joint
