The G23 is a 700c tubeless carbon clincher wheelset, with a generous 23mm internal width, specifically conceived to meet the performance and ride quality demands of serious mixed surface cyclists. Smaller in diameter and lighter in weight, the 650B G27 is designed for the higher volume tires demanded by many riders on rougher and looser terrain. HIGH VOLUME G23 = 700c x 23mm Internal Rim Width x 35 – 45mm tire Rider’s looking for maximum versatility, speed and efficiency will gravitate towards the G23 paired with a 40mm tire.
