An all-around trail tire excelling on everything from loose cross country race courses to heavy all-mountain riding. Excellent all-round performance Specification Conditions: Loose over Hard Loose Medium Wet Cornering Control: 1 2 3 4 Rolling Efficiency: 1 2 3 4 TPI: 60 Bead: Foldable Ply Construction: Single Compound: Dual Max PSI: 60 Tech: Tubeless Ready EXO Technology Tubeless Ready: Tubeless tyres provide the rider with many benefits: the ability to run lower air pressures which improves traction; lower rolling resistance when compared to a tube-type tyre; & less chance of flatting since there is no tube. Maxxis Tubeless Ready (TR) tyres provide the benefits of a UST tubeless tyre without the weight penalty. Our TR tyres use a standard casing & require the use of a liquid sealant in order to make them airtight. EXO: An extremely cut-resistant & abrasion-resistant material added to the sidewalls of select mountain tyres. This densely woven fabric is also lightweight & highly flexible ensuring that the performance of the tyre remains unaffected. Choose EXO Protection for exceptionally rocky treacherous trails where the chance of sidewall cuts & abrasions is high.
