Schwalbe G-One Ultrabite tyres review

Schwalbe's most aggressive gravel tyre supplies lots of grip and is surprisingly fast rolling – but it's best for rocky conditions as lateral grip in mud is a little lacking

Schwalbe G-One Ultrabite
Cycling Weekly Verdict

The Schwalbe G-One Ultrabite – particularly in its widest casing – is superb for loose and rocky terrain as well as having good mud-shedding capacity for when the slop covers the hardpack. Despite the aggressive tread, the Ultrabites do roll surprisingly quickly on the tarmac, albeit still slower than a more moderately treaded gravel tyre. The one downside is that in off-camber pure mud, the horizontal knobs of the centre tread don’t offer much in the way of lateral grip.

In fact, it's one of the most aggressive gravel specific tyres around; there aren’t many alternatives that match this level of burliness.
