The Thunder Burt is documented for dry cross-country conditions, with numerous tread edges for hard ground and shoulder knobs for cornering. This transparent-sidewall 29 x 2.1-inch version pairs Speed compound with Super Race casing.
The folding 67 TPI tire is tubeless-ready. Check the rim requirements and clearance for the selected 2.1-inch width, particularly when replacing a tire of another width. Its dry-XC brief should guide the choice when considering more heavily treaded options.
