Profile Design Altair Semi Carbon Clincher 52
1756 grams, 52mm deep
The Altair Semi Carbon Clinchers split the difference between the conventional rim width of the American Classic wheels and the ultra-broad profiles of the Bontragers and Hed wheels. Their 21mm-wide rims increase tire volume and help moderately dampen road vibration on straightaways and through bends. The wheels have a firm, laterally resilient feel, possibly because of the structural carbon rim. Combining the structural rim with the moderately high-volume tire bed give the Altair 52s an interesting combination of acceleration, ride quality and agility through technical descents.
