Thank you for the in-depth, technical review. I like that they make a relatively light Grid Trail version with the soft T9 rubber. Gripton has been used as a term for Specialized rubber since at least 2016. Ever since Wolfgang Arenz (now of Wolfpack Tires) helped develop compounds for the brand. The same guy worked in rubber development for half of all tire brands (Conti, Speci, Schwalbe). Is T7 a new compound or is it the same rubber as was used on the previous gen tires? But what would that mean, given that Grid and BLK DMND had different rubber?
