This trend is unstoppable: Tyres on gravel bikes are getting wider and wider. Tyre giant Schwalbe is responding and is launching two of its most popular gravel treads in extra-wide versions. The tried-and-tested G-One RX Pro and G-One RS Pro models are now available in extra-wide 60 mm tyres. This is the German manufacturer's response to the growing demand for even more versatile gravel bike tyres for extreme use. Fun fact: 60 mm is equivalent to 2.35 inches. Not so long ago, this width was reserved for downhill-orientated mountain bike fullys. The new sizes are now available from specialist dealers.
The G-One RX PRO in 60-622 or 29 x 2.35 was specially developed for the extreme demands of ultra-bikepacking. For multi-day races over thousands of kilometres, three factors are crucial: reliability, durability and optimum riding characteristics - even when fully loaded. The tyre in the new size weighs 815 grams. The RX Pro is at the "off-road end" of Schwalbe's gravel range. It comes exclusively in black and Race-Guard version with the fast Addix Race rubber for 68.90 euros.
With the G-One RS Pro in 60-622, Schwalbe appeals to gravel bike riders with generous tyre clearance - and the tyre manufacturer even wants to target XC mountain bikers with this semi-slick. The focus is on maximum damping and versatility on demanding terrain. The tyre is said to weigh 750 grams and comes exclusively in black and Race-Guard design with the fast Addix Race rubber for 68.90 euros. The G-One RS Pro is the fastest gravel tyre in the Schwalbe portfolio.
In addition to the new 60 mm tyres, Schwalbe is now also offering the G-One Overland Pro in size 55-622. According to the manufacturer, this tyre is the ideal choice for bikepacking adventures of all kinds and is an ideal intermediate size in the extended gravel portfolio.
The fact that the XXL tyres work is demonstrated not least by various successes in classic gravel races. In everyday use, however, the tyre clearance of most gravel bikes remains the limiting factor for the time being. Only very few current bikes can accommodate the new XXL tyres. But this is likely to change. The wide tyres offer more comfort, better traction and greater puncture resistance - perfect if the gravel bike is ridden a lot away from asphalt and fine gravel.
