The DCR grip formula was created with two things in mind, superb durability as well as superior comfort. Subrosa was able to tweak the blend of their existing grip rubber by adjusting the levels of rubber, oils, resins, & fillers that made up the actual rubber blend. By doing this Shadow was able to create their own rubber formula that had two characteristics that aren’t normally associated with each other: The perfect grip feel as well as outstanding durability.
