Description

Rocky Mountain high.

Taking the trail bike to uncharted levels, the six-inch (152mm) travel Yeti SB-66 Carbon Mountain Bike Frame expands on the quickly building, trail-dominating reputation of Yeti's Switch Technology suspension by adorning it with a weight-dropping and stiffness-enhancing carbon chassis. In fact, the hand-laid high modulus carbon front and rear triangles knock a whopping pound and a half off its aluminum counterpart -- and that's without sacrificing anything to the stiffness department. That's right, you're looking at a six pound (2.72kg), six-inch trail bike.

This is the first Yeti SB (Super Bike) series frame to feature collet-type pivot hardware, which ensures the correct bearing preload while protecting the structural integrity of the carbon fiber. Enduro Max angular contact bearings fill the bores and offer ultra-tight, flex-free tolerances while easily managing side loads that would send conventional cartridge bearings straight to the dump.

The heart of the SB line lies in the suspension design. Unlike multi-link systems, which require linkages packed in between the main triangle and rear triangle, Yeti's Switch Technology features an eccentric mechanism buried low in the frame-enabling super-short chain stays and a low center of gravity for lively handling. This compact eccentric continuously adjusts the lower pivot position for a rearward, small-bump-damping axle path while maintaining a firm, pedal-friendly platform. Towards the end of the suspension's travel, the eccentric rotates in the opposite direction for a responsive mid-stroke, and finally to the end position where the suspension becomes progressively stiffer to provide big hit absorption. Think efficient pedaling perfectly meshed with big hit capabilities.

Yeti SB-66 C DetailAside from the major drop in heft, updated bearings, and hardware, the SB-66 Carbon chassis is loaded with new-school features. The boys in Colorado provide the option to run a triple, double, or single ring with a chain guide thanks to removable ISCG tabs. There's also routing for a seat dropper post, a direct mount for the front derailleur, and it's only available for the stiffness enhancing 12x142mm thru-axle. A tapered inset head tube (ZS44/ZS56mm) ensures front-end precision and strength for long-travel forks. Yeti recommends a fork in the 150-160mm range (resulting in 67 or 66.5 degree head tube angle, respectively). If you're aiming to charge through the rough, then match your SB-66 C to a 160mm fork with oversized stanchions, but if you want an all-day backcountry machine, add a 150mm travel fork with 34mm sanctions for climbing ability and some weight reduction.

Like all factory-prepped Yetis, the SB-66 Carbon has its rear suspension motion controlled by the highly respected FOX FLOAT CTD Adjust. However, this isn't any run-of-the-mill FOX Float rear shock. Yeti has long worked closely with FOX Shox—including their jointly run World Cup mountain bike race team—so you can be assured that this factory-tuned Float CTD (equipped with a Kashima coated shock shaft for ultra smooth and durable out-of-the-box performance) is the perfect match to the SB-66 C.

The Yeti SB-66 Carbon Mountain Bike Frame is available in the color Raw Carbon with either Black, Grey, or Turquoise decals. It comes in four sizes from Small to X-Large. The SB-66 uses a High Direct mount for the front derailleur, a post mount rear disc, a 73mm English Bottom Bracket, and you'll need a 30.9mm seatpost.

US Yeti dealers are prohibited from shipping Yeti bicycles to any country other than Canada, Mexico or the US.

Amazing!

I love this bike! People stop and admire it. I get the comment, "That looks fast" almost every time I go for a ride.

Amazing!

Best Bike EVER!

  • Familiarity: I've put it through the wringer

I bought this bike last summer and since then have ridden it all over Colorado and Utah. It simply is the best bike I have ever ridden. It climbs like a gecko and descends like a snow leopard on crack! It is a little extra work on the uphills but makes the downhills so worth it. If you truly enjoy riding then this bike is for you.

SB for Super Bike

  • Familiarity: I've used it several times

That bike is a killer. It's clearly the best bike I have ever ridden.
It climbs very well, without creating pedal bob, and it is a pleasure to ride down.
I wouldn't say it is a "quiet" bike", it doesn't translate a rough terrain into some gravel road. Instead you get a direct feel of the terrain, but in a good way, because you can feel the bike giving you grip on any terrain. Plus the suspension is quite progressive, so even on big impact, you keep control.

So to summerize, it is a bike I think is for people with a good level of fitness and skills, because it is a bike that shows his best when ridden hard. You'll probably find your limits before the one of the bike.

I'm 5'9 and I weight 135 pounds and I love my S frame.

Love this bike

  • Familiarity: I've put it through the wringer

I have had the alloy version and recently upgraded to the carbon version. This bike seriously rips. It is an attention grabber on the trails as well. This bike climbs extremely efficiently and bombs downhill.

SICK SICK SICK!
Love this bike! I was pedaling an "old school" 4-bar linkage bike before this (2010 Kona Dawg Deluxe) which sucked on the uphills with all the pedal-bob (even with pro pedal not too efficient), but was hard to beat on the downs as far as plushness. The SB-66C retains all the plush of the downhill with more responsiveness, destroys the climbs efficiently, and sheds considerable weight to boot. This bike BEGS to be ridden aggressively. It seems like the harder I ride it, the more efficient it is on the up and the down. If you're the type of person who likes to be their own chairlift and rides as fast as possible on the way up and down this is the bike for you. Love it!

I am 5'6 and 140lbs riding a size S frame. Fits perfect with a short stem (45-55mm).

Details on my build:
SB-66C Frame
Rock Shox Lyric R 160mm
Full XT drivetrain w/ Raceface NW 34t chainring up front/ 11-36t cassette rear
Easton Havoc bars (711mm wide I think..)
Stans Flow Evo rims on Hope Pro 2 hubs (142x12 rear, 20mm thru up front)
Nukeproof Ion pedals because I hate SPDs
2.35 Kenda Excavators for tires.

What a ride!

  • Familiarity: I've used it several times

I really don't know why YETI is dicontinuning the SB-66C? It's a brilliantly balanced bike. I climbes effortlessly and descends with confidence. If you're looking for a high quality do-it-all bike, get it while it's still availible.
I've had no issues what-so-ever. It's a joy to ride.

What a ride!

This Bike Rocks

  • Familiarity: I've put it through the wringer

Great pedal platform, Switch eats up the down hills. The Fox CTD is an added bonus. Go with XT or XTR brakes. They are awesome. Been to Moab, Sedona and Western Nc on this bike. It takes it all.
