As soon as 29” wheels were legitimized in the MTB world, the race began between manufacturers to cram those wagon wheels into the most compact dimensions possible. The low rolling resistance was instantly appreciable, but it took a little time to figure out how to make a 29er feel lively and agile. Canfield Brother’s original Yelli Screamy was the first hardtail 29er with sub 17” chainstays, giving it the playful character of a smaller bike.
“The original Yelli was the 29er that we wanted to ride,” said Lance Canfield, owner and designer. “It didn’t exist, so we built it. It’s fun up, down, in the air, pretty much anywhere you want to take it.”
The second generation Yelli Screamy retains the same character but features all new tubing, ISCG mounts, a 142x12mm rear axle plus some key updates to keep up with current trends and innovations…
Like its predecessor in the clip above, the new Yelli Screamy features Canfield’s aggressive all-mountain geometry. The chainstays remain at a stubby 16.7”, and the head tube angle is either 67º with a 140mm fork, or 68º with a 120mm fork. The top tube dips low for plenty of standover clearance when you’re getting rowdy in the rough. The frame is crafted from 6061 aluminum and has a tapered head tube, 73mm BB shell, and accepts 30.9mm seat posts.
The new version brings the Yelli Screamy up to date with added features like stealth dropper post routing, and a 142x12mm rear axle. The 2015 frame features dropouts similar to those found on Canfield’s Jedi DH bike, and the new axle not only increases stiffness but also allows for greater compatibility with current all-mountain wheelsets.
“This bike is all about fun, and people ride it just as hard as they do their 6-inch bikes,” said Lance. “We wanted to make it just as easy to build it up to match.”
A redesigned yoke at the chainstay provides better clearance, fits higher volume tires and accommodates 1x drivetrains. The frame has a direct mount for a front derailleur if desired, and ISCG mounts if you prefer the extra security of a chain guide.
