There are at least four different black chili compounds on MTB tyres – XC, trail, enduro and DH in ascending order of stickiness. There might be even more! “Black chili” is an additive which improves flexibility and toughness, thus giving a compound better wear life, more grip and lower rolling resistance. I’ve used Barons, Trail Kings / Rubber Queens, Mountain King 2 and X-King and they’re all different. The Baron compound is fantastic – grips like a super tacky but rolls and wears like maxxpro.
Pure Grip are a cheaper range of compounds. And then there are the plastic ones which are awful.
Btw, iridemybike, that’s definitely a warranty issue – Continental will replace the tyre free of charge if you haven’t already binned it.
