2016-2017 EPO

Canfield Brothers EPO
The latest in a never ending quest to push product boundaries, Canfield Brothers is proud to introduce the EPO—the first carbon hardtail tough enough to wear a skull on the headtube. The Bros. ignored the perception of what a hardtail 29er should be with the Yelli Screamy, and carried that sentiment into carbon. At 1,450 grams, it is the lightest—and first carbon—Canfield frame ever produced, engineered for aggressive riders with signature Canfield Brothers 29er geo: slack and low with super short 414-millimeter (16.3-inch) chainstays. The EPO is light, stiff, stout and ready to attack whatever you put in front of it. If it wasn’t so much fun, it would feel like cheating.
