Test: Nothing is more important than contact with the road or, as it is in the gravel area, with the gravel. A tire has to be able to do many things, ideally everything perfectly. But it's a balancing act between grip and speed that manufacturers have to keep an eye on. Mixed tires are usually used, which are particularly fast on the rear wheel and have particularly high traction on the front wheel. The Schwalbe G-One Ultrabite could be such a tire for this combination.
Schwalbe G-One Ultrabite: assembly
By default, our test bike, the Bull's Grinder 3, Schwalbe X-One Allrounder tires mounted on the front and rear axles. So it made sense to follow Schwalbe's recommendation and only mount the Ultrabite on the front wheel. Because according to the manufacturer, the G-One Ultrabite is the ideal front tire in combination with the X-One Allround or a similarly fast-running rear tire.
The Schwalbe tire is fully tubeless-ready, but we still installed a tube. Mounting the gravel tire was relatively easy. However, we noticed the stable sidewalls when we applied the tire levers and determinedly levered the G-One onto the rim. He also finished cleanly and jumped into the rim flank with a lot of air pressure. Exactly what you would expect from a tubeless-ready tire. For our test drive, we pressurized the front tire with around 3,5 bar.
Schwalbe G-One Ultrabite: driving impression
It was tested on asphalt, gravel and forest soil and to get one thing straight away: We are thrilled with the grip. But first things first. The first few kilometers we rolled comfortably on asphalted paths. Here it is also immediately apparent that coarse studs are simply loud. But once you get used to it, it's no longer annoying. Here we were satisfied with the rolling resistance. But not jubilantly, which was probably due to the background noise. But that was probably more of a subjective perception.
In order to test the grip on the front wheel extensively, we chose our test route in the Bavarian Rottal over gravel roads and then into the forest. On gravel, especially in curves, the Schwalbe G-One Ultrabite conveys a lot of security, which is probably due to the massive and stable side lugs. Also in the delay was scored here.
You could absolutely rely on the grippy tires on forest soil and technical trails. The tire cleaned itself quickly and always offered sufficient grip and stability, even on loose ground. It was also important to adjust the air pressure accordingly and to increase the contact area. Due to the fact that we were only so massively equipped on the front wheel, the low air pressure was hardly noticeable even on the asphalt return journey.
