Schwalbe Ultremo ZX HD tyre review£37.99

Top all-rounder

BikeRadar score5/5

Schwalbe’s Ultremo tyres have always been top performers but the HD version finally delivers the survivability needed to make them a winning all-rounder.

The ZX HD version adds more shoulder rubber over an ultra high density protective layer. Initial longevity signs are great with no tearing, shedding or deep cuts.

The RaceStar Triple Compound feels great, too. It’s fast on the road, a feature that’s backed up on the rollers, yet still reliable through turns in wet or dry and clean or dirty conditions.

The 23mm is buoyant for back road comfort but light enough for sprints. The coloured tyres are slightly more slippery.

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.
