2017 Nimble 9 Boost

Canfield Brothers Nimble 9 Boost
The big-wheel revolution continues with the Nimble 9. The Bros. took what they loved about the revolutionary Yelli Screamy, and set about crafting a 4130 chromoly steel hardtail that looked good and rode better. The Nimble 9 combines the revered ride quality of a steel frame with a slack head angle, boost spacing, short chainstays (adjustable down to 16.25 inches via sliding dropouts) and clearance for wide tires. Whether you’re running gears or building the ultimate singlespeed, the Nimble 9 is the real deal.
