The G-One series is Schwalbe's line of gravel tires. At the time of writing, the G-One line consists of 4 tires from fast tread to aggressive tread: G-One Speed, G-One Allround, G-One Bite, and G-One Ultrabite. At the moment only the Ultrabite version is available with Schwalbe's latest Addix compound. We'll test the other versions as soon as they become available with the new Addix compound.

The G-One Ultrabite has aggressive knobs that we would expect more from a mountain bike tire. We can't imagine that you would want to go even more aggressive on a gravel bike because you might be better off grabbing a mountain bike.


The G-One Ultrabite in size 40-622 that we have tested is composed of a MicroSkin TLE casing and the Addix SpeedGrip compound which we also know from Schwalbe's mountain bike tires. The TLE casing has reinforced sidewalls which makes this tire suitable for tubeless use.

The CX/Gravel section is a multi tire size section, air pressures have been adjusted to the measured casing width.

All numbers are for a single tire at a speed of 29 km/h / 18 mph and a load of 42.5 kg / 94 lbs.

Use the formula: RR (Watts) = CRR * speed (m/s) * load (N) to calculate rolling resistance at a given speed and load.

The G-One is a very aggressive gravel bike tire. Unfortunately, the tire is not as fast as what we were used to from the Schwalbe tires from the past. The tread is very aggressive, if you are mainly looking for a lot of grip on your gravel bike, these are probably some of the best.


The weight is very disappointing from this tire, specified is an already high 480 grams but our tire weighs 564 grams which we would certainly return if we used them for any reason other than this test. We rate this tire a 3 out of 5 mainly because of the aggressive tread profile that is unique in this size.
