The Schwalbe G-One RS Performance Tubeless Tire runs a semi-slick center tread that keeps rolling resistance low on hardpack and pavement, while paired outer blocks pick up the grip and self-clean the moment the surface turns loose or muddy. That tread sits on an ADDIX Green compound built from Fair Rubber natural rubber and recycled carbon black pulled from Schwalbe's own tire recycling program, cutting CO2 impact without giving up everyday performance. What Our Gearhead(R) Experts Are Saying:"I felt the tread do its job in real time on a ride that started on a smooth fire road and dropped into a muddy switchback section. The center stayed fast the whole way out, then the outer blocks took over the second the trail turned soft, without any hesitation in between."
