Short-knob center tread cuts down on rolling resistance while still providing enough bite for out-of-the-saddle traction. Center and intermediate knobs on the Raddler are slightly taller than those of the original Riddler, thereby increasing tire lifespan without negatively affecting rolling efficiency. Tall, toothy outer lugs ensure your favorite gravel descent doesn't unravel in the final corner. Single-ply 60tpi casing provides dependable protection at a minimal weight.
