Michelin Mountain X’trem Expert review£29.99

Michelin's Mountain X'trem Expert tyre has been a test favourite for a while, and now they've tweaked the recipe to make it even better. The Comp 24 DH-based tread, with soft grey compound over harder base compound tread, still has the same insanely grippy performance as before.

Michelin's Mountain X'trem Expert tyre has been a test favourite for a while, and now they've tweaked the recipe to make it even better.

The Comp 24 DH-based tread, with soft grey compound over harder base compound tread, still has the same insanely grippy performance as before. New additives promise longer tread life, though, and it's certainly not tearing up as badly as the old one did.

A new casing on the Light Enduro versions we tested also adds pinch puncture protection while keeping it impressively smooth rolling. The 2.5in version also comes with the full three-layer side/four-layer under-tread Reinforced treatment.
If you want maximum grip on loose, rocky or mixed terrain, with decent protection but not excessive weight (ours was 844g), this is the pup to pump up.

Guy started filling his brain with cycle stats and steaming up bike shop windows back in 1980. He worked the other side of those windows from '89 while getting a degree in “describing broken things covered in mud" (archaeology). Dug historical holes in the ground through the early '90s, then became a pro bike tester in '97. Guy has ridden thousands of bikes and even more components the world over since then and can remember them all in vivid, haunting detail. Can't remember where the car keys are, though.
