4Cross-Edition. Nobby Nic and Racing Ralph now come in a new and unique 4-Cross edition. The special GateStar compound was developed in cooperation with multiple World Champion and Worldcup winner Jared Graves. The PaceStar difference: Extremely soft shoulder mixture. It gives the tire exceptionally adept cornering ability. The stable SnakeSkin sidewalls also make Tubeless conversion very simple.
Folding A folding tire is a special version of the clincher tire. The wire bundle is replaced by a bundle of kevlar strands. This enables the tire to be folded up and depending on the tire size, makes it about 50-90 g lighter.
