Tufo Thundero HD 622 x 40c Gear Levers & Shifters Aluminum Pulley Wheels for SRAMThe Thundero can do it all. The middle part of the tread, composed of tightly packed cubes, creates speed and surprisingly quiet rolling with three indented rows of knobs on the outer tread, which bite literally into any surface. This provides excellent grip even on unpaved surfaces and allows you to turn sharply. The wide tread and the durable flexible Jubena layer covering the sidewalls protect the tyre from receiving damage from stones.
