Waxed Rival eTap AXS D1 ChainChains are waxed on demand using Silca Secret Blend Hot Wax. Wax offer greater component longevity, cleanliness, and better efficiency. The wax is a solid lubricant meaning that dirt and contaminants can't get in the chain which keeps your chain from wearing as quickly. In almost every application, we recommend wax.
