Bike Launch | The New Yeti SB165 Is A 27.5 Trail Monster

by 5

Today, Yeti is announcing the new Yeti SB165 bike and frame. Slightly confusingly (though we’re sure it’ll make sense eventually) on the back of last year’s SB130 and SB150 bikes (which were 29ers and had 130mm and 150mm rear travel respectively) this new bike has 165mm of travel, but with 27.5in wheels.

Look. Then look again. That is both steep and slack. All at once

Unashamed Fox coil shock going on there.

Still with us? Because this is a bike that needs some closer looking at. In brief, it’s a 180mm/165mm trail, all mountain (is that still a thing?) and enduro race bike with a super steep seat angle and a super slack head angle.

Big rotors. Might as well go big, eh?

Some serious pedigree there

The Yeti SB165 is set up to pair with a 180mm fork (in this case a Fox 36) and runs a coil Fox rear shock for its 165mm of travel. The whole bike bears little similarity to any current Yeti and even with the 150mm travel SB6LR, the nearest previous machine in the range, with the shock now allowing room for a bottle cage and a whole new set of numbers. To say that the SB165 is longer and slacker than before is also an understatement. The head angle is now a downhill bike-like 63.5° while the seat tube is a triathlon bike-like 77°. The reach has been extended to 430mm on a small, 460mm on a medium, 480mm on a large and 505mm on an XL.

Loads of room here.

The suspension is set up for either a high volume air shock, or a coil-over rear shock. The Fox 36 up front is a shorter 37mm rake. As Yeti puts it ‘It’s the slackest sled in the line’. And Yeti goes on to say:

“The Switch Infinity platform provides us the ability to manipulate the bike’s kinematics and tune leverage rates within a wide range, while maintaining the same proven anti-squat properties. At 27.5%, the SB165 leverage rate is the most progressive in the line, optimized for the linear spring rates of a coil or high-volume air shock.” said Yeti Director of Engineering, Peter Zawistowski. In layman’s terms, it climbs great (even for a big bike) and crushes the downhills.

The SB165 T2, Yeti’s most popular kit, is spec’d for steep descents and technical, big consequence riding — 200mm rotors and SRAM Code RSC brakes, custom DT Swiss EX 1700 wheels are stiff and durable, and the OneUp Bash Guide keeps it all together in rough terrain. It has water bottle brackets in the main frame, internal routing and an optional shuttle protector. Optional, because some people might just leave the truck at home from now on.

DT EX1700 wheels are light and wide but strong too

You know that a new Yeti is not going to be a cheap bike, but even Yeti die-hards are going to have a bit of a sharp intake to hear that a T-series frame will be £3,799. However, full builds (with the cheaper C-series carbon) will start at £5399.

Here’s the full SB165 Pricing

SB165 C1 C-Series Bike – SRP £5,399 / €6,090euro

Chipps wasn’t around for the dawn of mountain biking in the UK, but he likes to claim that he arrived in time for second breakfast (about the time he shows up for work, then…) starting in the bike trade in 1990 and becoming a full time mountain bike journalist at the start of 1994. Over the subsequent quarter century, he has seen mountain bike culture flourish and diversify and bike technology go from rigid steel frames to fully suspended carbon fibre (and sometimes back to rigid steel as well.)

His riding style is best described as ‘medium, wheels on the ground, trail riding’ though he’s been spotted doing everything from endurance downhill racing to 24 hour cross country racing. He favours mid-travel trail bikes and claims to be wheel-size, gear, brake and tyre agnostic. In fact, his garage spans most bicycle flavours, taking in steel hardtails, carbon trail bikes, even a mountain bike tandem, along with road, touring and gravel/cyclocross bikes.

While he’s happy to chat about bikes all day, his real interest is in the people and places that bikes can introduce you to and he talks as fondly about the trails he’s ridden and riders he’s met as the bikes that took him there.

    Pedant alert!
    37mm offset I believe

    Thanks Stiggy, I shall change…

    Oooh! I need that in the black please.
    (Despite my the bulk of my riding being done on a rigid 29.) 🙁
    A very pretty and sorted looking bike.
