Astonishingly light and grippy in mixed conditions, but rather fragile

We know this tyre was in our summer speed tyres issue but it went so well in the mire of Mountain Mayhem 24 hr race that we had to include it here too.


Continental haven’t designed it as a wet weather mud tyre but the wide-spaced triangular stud and ‘M’ block design bites into soft stuff really well. It’s stable enough to push hard under braking and cornering when you’d be backing off on most tyres.

At Mountain Mayhem – a real Somme of sludge, wet rock and roots, off-camber grass and general slippery evil – we rode it harder every lap, despite deteriorating conditions and it never let go unless we were being really stupid.

Fast clearing and ridiculously low weight mean instant acceleration on ?rmer bits too, and it runs well all summer. The new Black Chilli compound is really impressive in mixed conditions without feeling slow on the ?rm stuff or ripping apart quickly.


Unfortunately it only comes on the featherweight ‘Supersonic’ carcass version, which needs more TLC than most tyres and plenty of pressure to keep it stable. The similar but burlier Mountain King mixes Black Chilli with reinforced ProTection sidewall though.
