Steilacoom 700 x 38Description The ultimate cyclocross tire is also a great choice for mixed surface rides. Named after an iconic cross course at the foot of the Cascade Mountains, the Rene Herse Steilacoom uses their revolutionary dual purpose knobby tread. The tire is always supported by the same amount of rubber, whether its rolling forward or leaning into a turn. This gives you uniform grip at all times whether on a muddy cyclocross course or during a paved descent
