Schwalbe's G-One R line gets its third member: The G-ONE RX focuses on the best possible off-road performance and is revealed today.    It joins the G-One R all-purpose tyre and the G-One RS, a semi-slick tyre that stands for maximum speed like no other. Off-road, especially on rocky and muddy terrain, enormous amounts of grip are required, this is where the G-ONE RX feels most at home.    The tyre retains the boomerang design tread pattern of the G-One R for low rolling resistance and grip on steep climbs. However, the knobs are more pronounced and the focus on off-road surfaces is particularly evident in the tread detail   Features Paired outer blocks ensure maximum cornering traction. The concept originates from the cyclo-cross sector, where Schwalbe has already successfully implemented it on the X-ONE R. The intermediate area is open to ensure the best grip on steep climbs and good self-cleaning even in muddy conditions.   Specification Version: Super Race, V-Guard tyre. Compound: Addix Race. Bead: Folding . EPI: 67. TLR (tubeless ready). Max PSI: 55.
