A reinforced Trail TLR casing anchors the Mazza XC-Trail 29in TLR Tire Set, two tubeless-ready 29er tires for trail and all-mountain riding. The casing pairs abrasion-resistant 120 TPI nylon with extra protection down the center strip, and anti-pinch flat inserts sit low on each sidewall for lateral stability at speed. Ramped leading edges on the tread roll over technical ledges, and the 4C Graphene compounds stay tacky on wet or dry switchbacks. What Our Gearhead(R) Experts Are Saying:"On a long, rocky descent the small hits arrive as a soft thud instead of a jolt, because the casing flexes over each one before it reaches the bars. My hands stayed loose all the way to the bottom."
