2015 Canfield Yelli Screamy hardtail 29er, frame shot

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.

Awesome… Don’t forget to look at the Nimble9 and EPO- similarly conceived frames in chromo and carbon, respectively. Bikes with geometry like this and with big wheels were my dream, and having them available on production bikes means I don’t have to go custom. Just one question- how much does a Yelli frame weigh? I suspect it’s on the heavy side, the chromo Nimble9 frame weighs around 6.5lbs as I recall. Lotsa tubing there.

The Yelli needs to acquire the geometry of the EPO and THEN it can be considered next generation. 31.6 seat tube would be nice as well…

@ works

I’m certain they’ll get right on that.

Should they recycle the current run of frames or just send ’em off to the landfill?

@Tim – per Canfield directly – rough numbers on our medium hardtails are:
EPO – 3.15lbs
Yelli – 4.75lbs
N9 – 6.75lb

I have a medium N9 that arrived the day the EPO was announced and obviously before the new YS here was announced. It is by far the most fun I have had MTB and a perfect bike for where and how I ride. I don’t think the new YS will get me off the N9 but the EPO is surely tempting. And the Brothers customer service is second to none FWIW.

Yikes, that’s a terrible promotion vid.

@Tim The On-one Parkwood & the Titus Fireline evo Ti are built in a similar vein to these… & the Ti one may offer the handbuilt, lightweight ride you desire.

@Doug, looks like Bike Rumor found an old video from the original Yelli. That’s not recent at all.

@Tim, the Yelli frame is 5.1 pounds.

@Yob, what Geo in particular do you think the Yelli needs to aquire from the EPO? I was just looking on their charts and the EPO appears to have 1cm shorter stays and 13mm higher BB, but then I noticed that the Yelli was measured with a 100mm (500mm AtoC) fork wheras the EPO was measured with a 140mm (550 AtoC) fork.

@bikesarefun – LOL. No.

@DCS – I believe that is the weight for the last version – the new version dropped over 1/4#. See the weights I posted above directly from the Brothers.

@bikesarefun – clearly you’ve never dealt with the Brothers before or you wouldn’t have posted such a troll comment.

At the end of the day, you can’t go wrong with any of these frames from Canfield. I have a short inseam combined with the desire for carbon again has me leaning toward the EPO. That being said, the Nimble9 is so much damn fun.

Forget what you have been told. 29ers are still the sh*t.

@TheKaiser, in addition to the shorter stays and LOWER BB height (if comparing apples to apples with a 140mm fork on the Yelli) the EPO has a steeper seat tube and thus, longer wheelbase. All of these differences represent, to me anyway, the “next level/generation” of geo.

I was told that the new one is heavier than the old one.

So, who wants to buy my ‘old’ one that’s three weeks old? Sure wish Canfield would have told me that the new one was about to arrive.

It already existed.

canfield just copied it.

Pretty crappy that they would claim to have invented short stay 29ers.

Ol’ Shel’ – Where’s the proof? I followed this model since it came out and the only other model that may have doing the dh/am HT 29er with ultra-short CS, MAY have been the Chromag. Back in like 2011-2012, I only recall the Yelli, Chromag, followed soon by the HX2 (Chumba). Then later the Banshee… Am I wrong here? Pretty sure I’m not. So it is likely that this could be the first.
