Schwalbe G-One Speed Tubeless Road/Gravel Tyres - 30/40mm (Pair)

A racing tyre for the toughest jobs. With its large volume and V-Guard protection the G-One Speed is well prepared for such mixed surface ordeals.

Unleashing profile and breathtakingly fast – especially when large volume counts. As a 30mm wide road race version with V-Guard protection, G-One Speed is a tyre for the real tough jobs. The new G-One Speed is an evolution of the former S-One and Big One.

Schwalbe have launched the new G-One Speed Tubeless Tyres designed to take on the toughest classic races and perfect for winter training

The Schwalbe Tubeless road tyres consistently win plaudits from journalists and customers alike. We have been testing them for a long time and have been very impressed. The One Pro's are Schwalbe's top of the range tyres and feature their triple compound tread so you get extremely low rolling-resistance combined with excellent grip and durability. The G-One Speed is available in 30mm which offers a large tyre volume and unbeatable grip in adverse conditions. A light dotted tread enhances grip even further and as a result makes this tyre ideal for use on wet and gritty winter roads.

Please note - we can only supply these tyres at the time of purchase of a Hunt wheelset. We cannot supply them separately.

The Experts' View

The highly respected German Magazine TOUR said "Unbeatable with punctures... – the "self-repair" with sealant means that no tube can compare ..."

Schwalbe Description

A truly thrilling ride. It's fast. It’s reliable. It’s light. The patented MicroSkin construction makes this all possible. - 70 g less weight, 15% less rolling resistance and improved cut resistance all around. This is the absolute top model from Schwalbe!

You can also use the Schwalbe G-One Speed with a normal tube, but its true strengths are experienced only in tubeless form

Tubeless Easy is the special Schwalbe technology for the next evolutionary level of the tubeless tyre. In practical terms, this means: A little liquid sealant is necessary, yet extensive conversion processes involving a lot of shaking and frequent re-pumping are not required. Compared to classic tubeless tyres, it is far easier to assemble.

MicroSkin: New key technology for Tubeless Easy. MicroSkin is the development which makes the difference compared to previous Tubeless tyres. The patented construction consists of a high-tensile micro fabric which is vulcanized together with the rubber compound and the carcass. MicroSkin envelops the entire carcass and facilitates a fault-free Tubeless Easy operation for high pressure tyres, not unlike SnakeSkin on an MTB tyre.

The new TUBELESS tyre is a new experience. With the new G-One Speed, the tubeless tyre provides ambitious sportsmen with significant benefits: It is faster, safer and lighter. All of those who have been able to ride with the G-One Speed have been impressed and immediately convinced. This is because the TUBELESS tyre with the G-One Speed does not only promise an advantage, the TUBELESS tyre with the G-One Speed is also a cycling experience.


The new TUBELESS tyre is already being used by professionals. Martin Elmiger, Swiss champion of WorldTour Team IAM Cycling, and Sylvain Chavanel, have already put the tubeless tyre to the test in extreme conditions. There is no tougher challenge for either cyclists or tyres than the cobblestones of Paris-Roubaix. Their initial scepticism gave way to huge enthusiasm for the tubeless tyres. Both cyclists were amazed at the speed and comfort with which the tubeless tyres guided them over the hellish cobblestones. They didn't experience a single snake-bite, by far the most frequent cause of blow-outs on the Paris-Roubaix route. Both cyclists completed the race without a single puncture. 

Fitting and Sealant

We can fit your tyres to your HUNT wheels prior to dispatch - just choose "fitted" option from the dropdown. Valves will be fitted, hand tightened and sealed around the valve base with a small amount of latex sealant. We fill the tyres with between 35 and 60ml of tubeless sealant (depending on tyre size) and the beads are fully mounted. We then run a small amount of sealant around the beads for quick and long lasting sealing. The tyres are inflated to maximum pressure and we then manoeuvre and rotate them to ensure sealant is dispersed well and a good seal all around the tyre is achieved. Your wheels and tyres are then left for several hours and checked for air leakage. Once everything is sealed correctly we lower the pressures to 50 psi for shipping and off they go. You receive your wheels and tyres set up and ready to go for hundreds, if not thousands, of miles of hassle free, low-rolling resistance, puncture-sealing riding.
