“SnakeSkin-Sidewall –
a light and flexible woven layer on the sidewall guards tires against abrasion damage.
Double Defense –
two system puncture defense with High Density Guard and Snake Skin sidewall. For the first time the protection belt from high-density Vectran fabric – the same used in the Ultremo – is also to be found in an MTB tire. While the proven SnakeSkin sidewall protects against sharp edged stones. There cannot be more security for light, fast off-road tires.”
If grips not much of an issue you could just try a snake skin ralph instead?
ETA – I went for the pacestar (harder XC) compound. I’m hoping this will make it a bit less draggy than a trailstar compound would.
