CHIMERA CHAIN ROLLER - 250/300 SWAPS

Replace the direct bearing roller with a more quite chain roller that utilizes low friction material to reduce drag. These are wearable items compared to the direct bearing rollers, but it will significantly quite down the chain noise.  Sold individually.  Directly replaces the double ball bearing rollers. Depending on which generation of the Chimera 250/300 swap mount you have, you may need to add a washer or file the spacer slightly to center the roller with the chain. These will work with non-offset sprockets. If you have offset sprockets or different sprocket positioning, you would need to align the roller with the chain.
