The Rocket Ron Tubeless Ready tire is one of the lightest 26" tires you can find. What Schwalbe did was take their proven Racing Ralph, space the tread pattern out and lighten up the carcass to bring you a tire that is in the mid 400 gram range. Clearly one of the lightest tires in its class.
When discussing the attributes of the Rocket Ron, weight (or lack of) is always the main topic, however, one of the most important features of the tire is how well it performs in all conditions, wet or dry. It is also quite durable for a super light race tire.
In terms of durability, Schwalbe uses a lightweight version of the proven Evo-carcass to help seal the sidewall when running tubeless as well as providing added durability from abrasion. The tires UST bead securely fits into a UST rim for excellent sealing action and prevent the dreaded burping of air/sealant during aggressive riding. Schwalbe U-block tread made from proprietary PaceStar triple compound offer incredible grip for a tire this light.
