Schwalbe G-One R tyre
The Schwalbe G-One R is a gravel tyre that offers an incredible mix of speed and grip that puts it at the top among other leading brands. There is little, if anything, to dislike, although the performance comes at a price.
The G-One is a race tyre with a new tread pattern, and a carcass layup that's been adopted from Schwalbe's premium road tyre, the Pro One. The G-One R is available solely in 700c wheel size and in two widths: 40mm and 45mm, both being tubeless compatible. The tyre carcass is what Schwalbe call 'Souplesse', the French word for supple, and is constructed with a 2-layer, 67 TPI carcass around the full tyre.
There's an additional V-Guard puncture resistance layer on the top with the tread pattern in a boomerang-shaped central tread and near-continuous tread moving towards the edge of the tyre.
Mounting the tyres to WTB CZR i23 rims was simple, and when used tubeless, they inflated easily with a track pump. First impressions when riding on surfaced roads were how quiet and smooth the tyre feels.
When things get rough and loose the performance is quite astonishing. The grip on rocks, stone or gravel tracks is outstanding.
Grassy moorland tracks are no problem, and the same goes for mud, the tyres managing to find traction in all conditions; the tread also clears dirt well after returning to drier surfaces.
Traction under braking is another highlight, and on typical loose gravel or forest roads where you might expect some lockup on the back wheel under heavy braking, they keep traction and ultimately allow shorter stopping distances.
