Schwalbe introduced their new ‘Tubeless Easy’ design last year at Interbike to make tubeless, well, easy. Schwalbe uses a fabric layer called Microskin that is vulcanized with the casing making the sidewalls nearly air tight, and a tight folding bead.
The G-One is Schwalbe’s new Tubeless Easy gravel tire. Our 38mm-labelled sample weighs 540 grams and measures 37.5mm wide mounted on a DT Swiss X1700 Spline rim with an internal 20mm width. The G-One is also available in a 700 X 35mm and 27.5 X 1.5″ version.
Based on experience with rims like those from DT Swiss, Next, Bontrager and Stan’s the G-One feels like it will be a reliable tubeless tire. It is said to require sealant to set up, which is true, but it was was ‘tubeless easy’ as claimed.
The actual weight is significantly higher than what is claimed, but on par with other wider tubeless tires. The tread goes over the tire’s shoulder adding casing protection and increasing off-road cornering confidence. Most of our riding with the G-One 38mm was with the tire tubeless mounted to the DT Swiss rim, with additional miles on the tire on a Next 30G wheelset with a 22mm internal diameter, not yielding much extra tire width.
We’ve put plenty of miles on the G-One and have some pretty detailed thoughts. Overall the tire set up and rolled well, but stay tuned to our full review in the next issue of Cyclocross Magazine to get the full details.
It goes without saying though that we think it’s great that Schwalbe is offering riders another option for a wider tubeless tire.
