Been riding around on the 2.4 Black Chilli Protection version for the past month, got them from Rock & Road in Stirling (my LBS), replaced a set of Maxxis HR’s. So far so impressed, not quite as good on damp rock or in mud as the HR’s, but infinitely better for maintaining speed.
They are a bit better in the mud now that I’ve lowered the pressures in the front, but it still wanders a bit. Cornering requires confidence, because they drift then bite which is great fun.
What took the most to get used to was the noise from the rear tire on tarmac, it sounds like you are riding along with a flat tyre!
Overall would buy them again. Also contrary to the website the protection is UST compatible (well according to the box I haven’t tried yet).
