Renthal's R3-2 O-ring chain is a high strength, sealed-ring chain with excellent impact load resistance designed specifically to withstand the stress found in off-road applications. This chain is the choice where a combination of high strength, light weight and maximum power transfer are important considerations. The O-rings help extend chain life by retaining the special vacuum-injected grease near the critical pin area. Chain comes pre-stretched to shorten break in period.
