Best of both worlds.

The Yeti ARC Carbon Mountain Bike Frame isn't another uniform 29er. It is a technology driven, race-ready hardtail that also uses 27.5in wheels for Small and X-Small variants. Yeti's notorious for doing things right, and the fact they've designed the ARC with rubber proportional to frame size, is case in point.

The idea of X-Large frames rolling on 26ers or X-Smalls on 29ers is quite skewed when a little logic is applied. Yet, manufacturers, remarkably, still insist on offering those options. When different diameter wheels are applied to a proportionately sized chassis, packaging and construction is much more natural -- and ride characteristics are enhanced for the end user. A quick look at the geometry difference between the 27.5 and 29 ARC brings this to light.

The ARC's geometry is nearly identical to the Big Top, not surprising given the expertise of Yeti and development of that frame, but there was never a Small or X-Small Big Top option. Yeti saw the issues with packing 29in wheels in compact frames and smartly stayed away. The Small and X-Small ARCs, on the other hand, enjoy the benefit of shorter chainstays, along with a lower bottom bracket and standover height thanks to the mid-wheel option.

While this is great news to anyone who fits the X-Small and Small ARC Carbons, there's much more going on here to warrant the coveted, heritage-rich ARC nomenclature. Born during the lightweight trend of the early nineties, ARC stood for Alloy Racing Composite, and the frames were constructed from aluminum Easton tubing. Carrying on that tradition, this ARC drops nearly a pound and a half from the Big Top by employing Yeti's extensive carbon proficiency.

This is Yeti's first full-monocoque carbon hardtail, but it's far from Yeti's first dance with the black weave. From carbon pivots to full frames, Yeti's stable has had some form of carbon fiber for the better half of a decade. The ARC's smooth lines, tapered head tube, and 12x142mm rear axle complement the unyielding and snappy carbon structure.

Also keeping the ARC tradition alive is an iconic looptail rear triangle that cleanly houses a post-mount for disc brakes. The bottom bracket is a traditional 73mm, but it also has removable ISCG mounts for chain retention. A high direct mount takes the guess work out of front derailleur placement. Yeti recommends a fork within the 100-120mm range with a 100mm placing the heat tube at 70 degrees; we'd expect a 120mm fork to knock the head tube back another degree.

The Yeti ARC Carbon Mountain Bike Frame is available in sizes from X-Small to X-Large and the colors Raw/White and Turquoise.

Where is the frame manufactured?

Hey Sheen,

Most Yeti frames are manufactured in Asia. Feel free to shoot me any more questions about Yeti Bikes or if you are interested in ordering this ARC Carbon Frame.

Climbs like a banshee

  • Familiarity: I've put it through the wringer

If you ride where the trails go up this is a bike for you. My size medium weighs in a hair under 20lbs without doing anything crazy, I could easily go lighter. The super stiff BB and rear triangle make mountains look like mole hills. The external/threaded bottom bracket is a BIG plus.

well i would consider Enve wheels a little crazy but it looks like a nice bike!

Hardtail perfection

  • Familiarity: I've put it through the wringer

I've been on the Yeti ARC for a few weeks now, and can say emphatically that it's an absolute blast to ride! I was on the cusp of sizes between small and medium, but opted to go with the smaller size as I generally prefer a more compact frame and I was excited about the 27.5" wheel size. I got the bike the day before doing a 50 mile mtb race in southern UT, and so had one spin to "get used" to it before a little trial-by-fire action. While not the ideal situation, the bike proved to have really intuitive handling and aside from sharper steering compliments of the smaller wheel size compared to the 29'ers I've been on most recently, it was a quick familiarization process.

The first thing to appreciate is that the bike climbs like an absolute demon. Weighing in at a about 19.5lbs as built (with pedals) certainly accounts for a lot of this, but so too the short chainstays and stiff bottom bracket area that transforms pedal input into seemingly instant acceleration. The more time I spend on the bike the more I find the handling to be that really elusive mix of razor sharp, but also highly predictable. The bike definitely rewards good line choice and smooth handling with a penalty for botched maneuvers...just like any hardtail. But with the proper attention and focus, it's a highly capable descender that also accelerates, climbs and corners with the best out there.

Also, worth noting, is that I've been able to run pretty large tires in this frame...up to a 2.4" Vittoria Goma. It was tight, without a lot of clearance for mud, but doable.

  • Familiarity: I've used it several times

Being 5' 10.5" I often seem to be between a Medium and Large in brands such as Santa Cruz, Jamis, etc. The Yeti ARC Medium is the perfect frame for my height. It allows me to run it as a light/fast/confident XC bike with a 100mm fork (70degree head angle) or transforms into an AM wonder bike using a 120mm fork and a meatier front tire (slacker/high-60's head angle) . The Zero Stack headset adds much flexibility for getting the cockpit and bar height just right. Stand over is awesome while allowing me to use a standard 350mm Thomson Masterpiece without maxing it out, and the top tube length is just right (in my case using an 85mm Easton Haven Stem). It is not often I find a bike that just fits so well. I find it to be one of few 29ers that doesn't really feel like a 29er in terms of handling and overall height. I have gone through many bikes that just didn't quite do it for me the past few years... I think the ARC Carbon is a keeper. I would like to take it for a few more rides at the tougher local trails but I just listed my other bike for sale. Only caveat is I suggest buyers consider black vs. green as the paint doesn't seem great with some atypical flaking vs. competitor paint jobs.

Can you share photographs of the paint flaking? Is this from stone chips or frame flexing/cracking? If you could do it over again, would you purchase a raw carbon frame?

Where is the geo chart for this ($2K)...

Where is the geo chart for this ($2K) frame? Your bike sizing process isn't accurate. I'm 5'5" with a 29.75 inseam (to pubic bone-can't go any higher) and it's telling me I ride a medium? Not. All medium frames have zero standover. Stand over cannot be adjusted, reach can be, with stem length, or setback seat post. You cannot accurately size a frame based only on top tube length. No one does it that way but tall people.

Best Answer

The Geo chart is listed at the bottom of the product page, just above the community review section. The fit calculator is a tool to assist in frame sizing, and slight errors in input measures can skew the results. At 5'5" you would be best fit on a small sized frame.


  • Familiarity: I've used it several times

Yeti nailed it. Great XC machine. I built the frame up with X01/XX1 components. With heavy flow EX wheels the bike weighs 23lbs even with pedals and two bottle cages. I'm 6'1 200lbs and ride a Large with a 90mm stem and the fit is great. I went with a Syntace P6 hiflex post because the frame is pretty stiff.
