Schwalbe G-One Allround 650b tyre review

We’ve been testing the Schwalbe G-One Allround gravel tyre in its 650b size to see how it copes with typical UK conditions

Cycling Weekly Verdict

The Schwalbe G-One Allround is a good option to add a bit of traction to 650b wheels without impacting ride quality or handling on tarmac. But a wider tyre would give better grip and roll-over.

We’ve had a Cannondale Slate on test at Cycling Weekly. The bike comes with 650b wheels shod with slick 42mm tyres. They roll well on road but soon give up on typically muddy UK bridlepaths. Enter the Schwalbe G-One Allround, one of the few tyres out there which is available in 650b size in a narrow enough 38mm/1.5 inch width to clear the Slate’s chainstays. It also has a tread pattern.

The Schwalbe G-One Allround is Schwalbe’s dedicated gravel tyre with closely spaced small, round knobs and uses Schwalbe’s Tubeless Easy technology for light weight and, as its name suggests, easy tubeless set-up.
