What makes a Superbike? Is it unparalleled descending chops, impossibly precise cornering, or spirited climbing? Perhaps it's all of them. At least, that's what Yeti thought when designing the SB-75 frame. Building on the stunningly successful SB chassis, and featuring Switch Technology, the '75 is the latest incarnation of a bike that can aptly be described as "super." Built around 27.5-inch wheels and 127mm of terrain-taming travel, you'd have a hard time finding a trail that it wasn't immediately at home on. And with the competitive pedigree that the SB series possesses, we have a feeling that you'll see these popping up on podiums in your neighborhood before too long. Say hello to the newest Superbike.

The SB-75 represents the latest version of Yeti's Switch Technology suspension platform. At a glance, it's easy to mistake the Switch platform for a linkage-driven single pivot, but hidden underneath the blue anodized hardware is an eccentric pivot. Essentially, this turns the SB series into a whole different beast. The eccentric pivot is basically a smaller pivot that's housed inside of a larger one. As a result, this system provides Yeti with an extra degree of control over the forces involved in the suspension action. In the beginning of the SB's five-inches of travel, the pivot rotates towards the rear axle. This means that it's rotating opposite the direction of the pedaling forces that are being applied through the chain. In translation, it neutralizes the pedaling force. So, the SB remains stiff and responsive under power, rather than allowing your pedaling force to influence the suspension.

As the bike compresses into the bottom of the travel, the eccentric link changes direction, rotating toward the front axle. This forward rotation keeps the chainstays short under full-compression, which keeps your weight centered in a neutral position relative to the wheelbase. And that all adds up to a predictable feel and control throughout the entirety of the bike's travel. But despite the sophistication of the Switch platform, it's easily serviced by home mechanics.

As for the upright link driving the rear shock, it works in conjunction with the eccentric main pivot to provide a firm, responsive ride that's still capable of erasing the roughest of trail chatter. And it has the added benefit of boosting the lateral stiffness of the frame, which keeps your bike tracking straight through G-outs, hard turns, and unpredictable terrain.

The aluminum construction of the SB-75 yields the strength that you'll need when the trails get hairy, while still keeping the weight competitive at just over seven-and-a-half pounds with a shock. The 67.5 degree head tube angle gives you the high speed stability that you'd expect from a bike bearing the Superbike moniker, but it's still precise for climbing and technical turns. The 13-inch bottom bracket height positions your feet below the centerline of the hub axles. In turn, this design yields a planted feel on rough terrain. And, on top of all this, 17.4-inch chainstays keep the '75 lively and responsive, while also providing plenty of climbing traction.

The SB-75 takes a 44/56 tapered inset headset. So, you're able to take advantage of the added stiffness of a modern tapered fork. The bottom bracket is a threaded 73mm shell, which makes installation and service a breeze, while also helping to avoid the creaking associated with PressFit bottom brackets. Mounting a front derailleur requires an E-Type direct mount. Or, if you prefer a chain guide to a front derailleur, there's replicable ISCG mounts available in both the ISCG03 and ISCG05 varieties. The rear wheel attaches via a 12x142mm rear thru-axle, which utilizes Shimano's QR thru-axle. The rear brake mounts to a standard post-mount, which accepts rotors from 160mm to 185mm. Additionally, the 30.9mm seat tube is compatible with almost every dropper seatpost on the market. And speaking of dropper posts, there's cable routing underneath the top tube in order to keep your cable arrangement clutter-free. And on the topic of cable routing, the rear derailleur cable is routed internally through the rear triangle. For those of you who intend on running a one-by drivetrain, such as SRAM’s XX1, the SB-75 will clear up to a 32t middle ring, with a 168mm Q Factor crankset.

The Yeti SB-75 Frame is available in four sizes from X-Small to Large and in the colors Black, Yellow, and Turquoise.

Hi, Good day. May i ask what is the material of yeti sb75 frame's pivot axles, pivot pinch bolts, shock bolts, rear dropout bolts (2 bolts each side) made of? Will them become rust? Thank you.

Most bolts are coated steel for strength. There are some Aluminum bolts in there. They won't easily rust, but maybe just a bit from tool scaring which is normal. As always, this is a high end machine and should be treated as such - meaning don't leave it muddy and wet. If you ride in the wet, hose it off and bring inside as soon as you get home.


May i ask does the yeti sb75 frame comes with rear 142x12mm dropout n axle ? Thank you .

These frames do come as 12x142 rear ends and axle is included. Give me a shout if you have any more questions or would like help with an order. I’ve got some miles on this frame and would love to share some setup pointers. I can also usually do a bit better on pricing.

I had the chance to ride this bike at Outerbike recently and it was,by far, my favorite ride of the weekend. I immediately felt at home on this bike with its ample stand over height,low bottom bracket and well-balanced geometry. That combo made the bike very snappy and agile with awesome flick ability on the trail. The bike also accelerated very well,especially in steep sections and the 5 inches of travel I felt was a great compliment to the 27.5 wheel size. I look forward to the carbon version one day!. If you have the means I highly recommend picking one up.

If you have specific questions on the bike or want an opinion on a component package do not hesitate to contact me. My direct line here is 801-736-6396 x 4074 or e-mail at

Does it have cable routing for a stealth...

Does it have cable routing for a stealth dropper post like my Rock show seat post 30.9mm?

you cannot run a stealth post on the SB models. It does however have cable routing on the bottom of the top tube. Look at the bright side, makes for way easier maintenance if you need to pull the dropper post out.

I started into riding on a 26" even though everyone at my local shop said to get a 29". i just did not feel comfortable on the 29 and if you don't feel it, it's not going to work. so, i went 26 and really loved it, i have no complaints about the 26 size. Having said all that, with the explosion of 27.5 bikes this year I started doing my research. I finally decided on the Yeti SB 75. I am loving it. My speed and abilities are going up every time I ride. The only issue has been that the 1x11 (XO1) 34T chain ring rubs the frame (chainstay). It clears by a fraction just sitting, but in rough conditions the ring barely rubs (paint off) the frame. Conversations with YETI they have said that yes they know this and a 34T is the max that you can run on a SB 75, but a 32T would be better for the clearance. I have switched to 32T ring and the clearance is fine with it. Now it just if I can be Ok with the ratios that the 32T ring brings. I really believe that this issue is more about the crank design than the frame design, but that is my opinion. I love the frame in every other way.

WOW ! It really make a difference

Is there a possibility of running a different cog on the rear to bring it back in line, ratio-wise, with the larger chainring?

Run a direct mount chainring and you'll increase you clearance between the chain stay and ring.

The Yeti SB-75 represents the latest iteration of the Colorado brand's Superbike platform. Intended to be the ultimate mountain bike, the 27.5-inch wheeled SB-75 employs five-inches of Yeti's Switch Link suspension in order to create the ideal blend of small bump compliance and pedaling efficiency. The burly aluminum construction keeps the SB-75 stiff when cornering, and helps it stick to lines on rough, high-speed sections. As with the rest of the SB lineup, the geometry is characterized as progressive, given its low bottom bracket, roomy cockpit, and relaxed head tube angle. A tapered head tube is compatible with the latest forks, and Yeti's replaceable dropouts allow the use of either a 12x142mm thru-axle or a 9x135mm QR. Meanwhile, the 30.9mm seat tube accommodates just about every dropper seatpost on the market. In other words, whether you opt for a complete bike, or choose to go with a custom build, the SB-75 accepts the latest components, which enhances its character as a premier new-school trail bike.
