The Maxxis Raze is a professional level cyclocross racing tire and the 33mm size is UCI compliant. Maxxis uses a slightly softer rubber compound in the Raze so the tire remains compliant in cold conditions for better handling and traction. Maxxis uses an upgraded casing to maintain and enhance tire performance at lower pressures.
The Raze is designed as an all around tire that performs in a variety of conditions. A closely spaced center knob section promotes fast rolling in hard pack while the more widely spaced square side knobs are meant to grip and shed mud.
