The Gravine is the most aggressive tread in the Challenge range, suitable for more demanding terrain. The tread depth is increased to ensure greater braking traction and superior grip on loose gravel and rockier terrain. The widely spaced knobs promote the expulsion of mud and debris and ensure traction when low-profile treads are insufficient. For higher speeds, lower pressures, and more difficult terrain, Challenge has developed a new technology applied to handcrafted construction. The new XP series adds extra protection on the sidewalls and tread (Xtra Protection - XP) for increased durability. This Challenge TLR model is compatible with hookless rims.
