PINKBIKE FIELD TEST
Yeti SB165
Words by Mike Kazimer, photography by Trevor Lyden
The SB165 showed up this season to stake its claim as the longest travel bike in Yeti's lineup, with 165mm of rear squish that's paired with a 180mm fork. It's rolling on 27.5” wheels, and according to Yeti was built for “hucking, sending, and enduro-ing.”
The SB165's geometry numbers follow the trend that was started with the SB130 and 150, and in fact, the reach numbers and seat tube angles are nearly identical for that trio of super bikes. Reach numbers range from 430mm on a size small all the way up to 505mm on an XL, with our size large test bike checking in at 480mm. It's built for the descents, but there's a relatively steep 77-degree seat tube angle to help create a comfortable climbing position. The chainstay length remains the same for all sizes, a fairly short 433mm.

www.yeticycles.com Yeti stuck with the Switch Infinity suspension layout for the SB165, a design that uses a translating pivot comprised of two short Kashima-coated rods in order to alter the amount of chain growth as the bike goes through its travel. Yeti wanted the SB165 to work well with coil-sprung shocks, so they adjusted the kinematics to give it a 27.5% leverage ratio progression; compare that to the SB150, which sits at 15%.
We tested the T2 version, which is equipped with a Fox Factory 36 fork, Factory DHX2 coil shock, SRAM X01 drivetrain, Code RSC brakes, and a DT Swiss EX1700 wheelset. Total price? $7,699 USD.
ClimbingThe SB165 has a gravity-oriented focus, but it possesses geometry numbers that make it possible to earn those descents without too much struggle. The slack head tube angle is noticeable on slower speed sections of trail, but it’s still manageable; it just takes a little bit more effort to navigate around tight switchbacks. It definitely feels like the type of bike that you’d use to search out gnarly descents rather than cruising through rolling terrain. Luckily, that's a fitting description of the terrain that's available around Pemberton – there are plenty of long climbs followed by long, steep and loose downhills.
When it comes to suspension efficiency, the Yeti does an excellent job, especially considering the amount of travel and the fact that it’s spec’d with a coil shock. It’s not a wallowy mess, and it’s totally feasible to leave it wide open for more technical climbs. The climb switch is pretty much just there for fire roads.
Descending The SB165's short chainstays make it really easy to whip around, and it feels great in the steeps and when jumping. A longer back end would likely give it even more outright stability, but that’d come at the cost of the ‘park bike’ feel. As it is, it's a quick bike that's easy and enjoyable to hop, pop, and manual whenever possible.
In the high-speed rough chunder it was a little easier to knock off line compared to the big-wheeled Specialized Enduro, but it still handle the chunky stuff very well. Bigger hits didn't pose any problems, and even when all of the travel was used there wasn't any harshness as the shock reached the end of its stroke.
The parts spec is very well matched to the bike's intended use, as it should be for the price. That being said, there's often at least one component on a bike that could be swapped out for something better, but from the suspension to the grips there's really nothing we'd change on this build kit.

Probably was an XC cooler prototype and not intended to be hucked to flat.
with this bike i reckon they should run 29ers because they can shred along the ground at higher rolling speeds.. this bike could then prove itself in downhill racing, eg beating all the downhill bikes.. once jono jones hops on this bike it will be unbeatable, the time that would come in would be outrageous. also my next point is i think instead of testing this bike at whistler they should test it at waitangi moutain bike park as this is more ur everyday trails and you will get more accurate testing results. another thing is i also dont think you guys know how much presure bikes are put under when they hit a gap jump... gravity+mass ov human=bike break in half... just imagine a heavyweight person getting on this bike? do you even think about the fatties in this world? no u dont... take eddie masters for example, he will shred on a fat bike because no brands are decent enough to make a beast that can handle the jandel. in conclusion i reckon this bike is abit sht and the only reason people season on it is becauz its cheap.

Also, the biggest lie the devil ever perpetrated among the Pinkbike commentariat is that 29ers aren’t fun.
They finally admit that conditions vary from day to day, which is unavoidable with just two people "testing" bikes. And this add to the obvious elephant in the room: that there is for more variability between runs than there is between bikes. They are just tossing dices and reporting the "results" as indicative of something.
It is almost impossible to "measure" the "speed" of a bike, maybe in much more controlled environment, with many more people involved, swapping all components etc ... but as they are conducted and reported these "test runs" are completely unreliable.
Very much fun that according to their random results this bike happens to be among the fastest but "If you’re looking for outright speed then you may want to look elsewhere"
I find the stability in the air causes me to take more chances.
Thanks for admitting it in a round about way
I do chase strava I do try to find the fastest line and link corners together perfectly and work on my braking and cornering all the time.
That's fun to me.
To some people fun is seeing how far around they can whip their rear end.
Personally I don't see the point.
But to each their own.
But to each their own.
I've smashed all my personal records from last year when I was on my 27.5.
All while being in much worse shape physically.
But ya pick a size and be a dick about it.
The only kind I ride.
I'm truly sorry you can't force me to agree with you over the internet and it's setting you off.
Truly sorry.
It's .7 mile and tight twisty fast with a couple punchy decent and climbs.
I had rode it the day before on my recluse and had managed to beat my PR by 5sec and put myself in 3rd place.
The next day I rode my 29er and smashed it by 12sec. That's the end of the story.
.. speaking to myself as I build up my new 27.5" bike...
Ha! But on the 27.5 conditions were wet, on the 29er dry. I prefer fair weather riding. I'll ride a 29er!
the universe will not allow this. the bigger wheels are exactly the same amount faster as they are 'more boring' and the smaller wheels are exactly the same amount 'more fun' as they are slower.
pick a wheel size and be objective about it.
The amount that a bike “turns quickly” is based on the amount of gyroscopic effect (weight of wheel) while the amount of rollover is based on the diameter of the wheel.
Now of course wheel diameter and the amount of gyroscopic effect are correlated, but it’s not like 10% faster turning means 10% more rollover. One is based on weight and location of that weight, the other is based on diameter.
First of all this gyroscopic effect (assuming people talk about the stability element) doesn't just depend on the angular moment of inertia, but on the angular velocity too. And for people riding the same speed, the angular velocity of the bigger wheel is inversely proportional with the diameter. So that makes the product of angular momentum and angular velocity increase proportionally with the larger wheel, not squared. Then again of course the mass is going to increase too with the larger wheel (bigger tire, bigger rim, longer spoke, bigger brake rotor probably) but I haven't looked into the proportionality. Back in the days the bigger wheels were typically narrower. When 2.4" wide was kind of the norm for 26", the big wheels were limited to 2.2" wide. Things may have caught up now but yeah, haven't looked into that.
Then as far as how flickable heavier wheels are, I feel that the gyroscopic precession actually works in your advantage. Bank the bike and it points in the right direction. And as bkes have gotten longer (so increased their inertia too) the increased inertia of the wheels is actually welcome to balance that. If your talking "gyroscopic effect" it is odd to not include the inertia of the bike in the equation. Now I don't run particularly big wheels but I moved to a longer bike at the same time that I shifted from running regular latex tubes in my tires to running the heavier ProCore system. Even though I scaled down from a 190mm front rotor down to 180mm I think the front wheel is much heavier than what I had and I appreciate that.
As this is a wheelsize discussion anyway, I'm actually curious how much a smaller wheel contributes to being allowed to pump the bike. My perception was that smaller wheels are better and I also feel much better riding my BMX with 20" wheels on the pumptrack than going with the full size MTB with 26" wheels. But the recent pumptrack world championship didn't necessarily support that. So yeah, would be interesting to see one skilled rider do a back to back test.

BB height is 9mm higher than stock, but less than 6mm more than an SB150... could just run a bit more sag?

Lawyers make good money, too. Why is this not a lawyer bike? Is it because lawyers don’t ride, but play golf? If that’s the case, doesn’t that make dentists much cooler than lawyers? Cut them some slack!
In all seriousness, I'm not a dentist. Just silly trolling. In recent posts, I've also defended Specialized, but I don't ride Specialized (anymore); and 29ers, but my personal bike is 27.5 (but I'd ride a 29er in a second). It just fascinates me how the myths ans dogma develop.
I guess the real reason is that there's not a well-sounding acronym for: people with a lot of money and very limited riding talent who can afford a bike that I can only drool over.
@ak-77: That makes sense to me.
But you’re right. Guys with $20k a year golf habits LOVE to talk about how silly and expensive MTB is.
A lawyer can show up in court with two broken arms, a dentist loses his lively hood.
So the funny thing about the meme is that dentist bikes are for people who overcompensate their lack of ability through expensive bikes. They also offer some sort of (unnecessary) feature that sets them apart from the mass of other bikes in order to show off their price tag.
And to be clear, I’m not coming down on you, personally. I just read comments like that all the time, and I just think what business is it of anyone else what someone else rides. Don’t hate, motivate. Let them be psyched about their bad ass toy. Be psyched for them. Then work hard and your day may come.
When I see a guy on a trail with a sweet bike, I’m like, “Dude, cool bike! Can I see? How’s it ride? I like those bikes.” If I see a dude who shreds, I’m like, “Damn, that guy shreds!” What he rides doesn’t come into the equation. At no point while I’m riding does it occur to me a guy doesn’t deserve a bike because he doesn’t meet my standards of excellence. I assume we are all out there on pretty much the same thing anyway.
"Dentist bike" reference?
Unless you’re racing, you’re going to have a lot more fun on this bike.

And it’s more important anyway for steering control.

I'd be curious how this built with 29 front and 170mm fork would ride and how it would compare to the Enduro.
No comments on the chintzy downtube protector and it's big gaps on where rocks are likely to strike it? Does Yeti require that pictures be taken with the crank arm covering the bottom bracket downtube junction?
