must throw out a good word too for the Dunny 218's fitted to this bike. The initial morning ride saw some rather chilly weather and the tires gripped well from cold with just a minimal amount of wheelspin (when getting hard on the throttle.) Once warm they stuck like glue and balled up like a GP spec tire. I’m not sure about longevity, but if fast Sunday blitzes’ are your thing these are the tires to keep you safe.
