The 195g Ultremo ZX clincher tire does an exceptional job of blending low rolling resistance, durability, lightweight, and razor sharp handling into a competition born and race bred tire.
Schwalbe's Nobby Nic is a tire for any occasion. It provides excellent traction by spacing the knobs out enough to leave void space for good penetration into soft soils and to offer decent mud shedding capability. The Nobby Nic rolls better than most high traction tires due to Schwalbe's alternating lateral clusters of "phase shifted blocks," which eliminate dissonant vibration and decrease rolling resistance by 15% over their first generation version.
Racing Ralph is the most successful off-road Schwalbe competition tire. The new version is even more merciless--lower weight, lower rolling resistance and better grip. It slices through terrain with its sharkstooth U-Blocks that make it grip much more aggressively, particularly in curves.
