- Multi-condition performance, superb braking traction and aggressive cornering bite. - From aggressive trail riding to the demands of downhill racing, the Newton ST delivers consistent cornering bite, predictable braking control and premium performance in ever-changing conditions. - The tread design features ramped center knobs to reduce rolling resistance, while tall, arch-supported side knobs provide ample braking and cornering grip. - Taller, meatier, and more aggressive than the Newton, the Newton ST ups the ante when front grip and loose terrain traction is a priority. - Available in two casings: Utilizing an EN casing paired with our R/T rubber compound, the Newton ST EN is lightweight with sturdy tread blocks. The Newton ST DH pairs our most robust casing with our softest RS/T rubber compound for unrivaled durability and traction.
