First Look: Yeti’s New SB140 – Splitting the Difference

If you’re a Yeti fan, it’s been a pretty good month. Mate I showed you the new SB160 a week agothen came Kazimer with the SB120, and today we split the difference with the also new SB140. There’s still a 27.5″ version in the line, but this SB140 is essentially the next generation of the SB130 (confusing, I know), and can be configured with either a 150mm or 160mm travel fork depending on the kit. building.

Like the other new bikes, the SB140 is offered in two flavors. Sign up for one of Lunch Ride’s beefier models with that 160mm fork and there are six complete bikes to choose from, all with a Float X shock and beefier tires and brakes. The C1, C2, and C3 are based on the heavier carbon frame and retail for $6,600, $6,900, and $7,800 USD. There are three other models based on the more expensive and lighter Turq frame that uses more expensive and lighter carbon fiber. You will need $8,800, $10,200, and $11,700 USD to get Q1, Q3, and Q4.

If you want that 150mm-travel fork and a slightly lighter build kit, pricing starts at $6,400 for the C1 or $6,700 USD for the C2. Turq-framed bikes start at the $8,600 T2 and $10,000 T3, or you can get the higher-end T4 for $11,500. There are eleven different SB140s to choose from, as well as the $4,500 USD frame, so head over to Yeti’s website for all the specs and details.

frame details

The new SB140 looks much like the previous version, but the differences are noticeable up close… or if you’ve already read about their other new bikes. The low-hanging, bulbous chunk of carbon in front of the bottom bracket has finally been trimmed down to a slimmer shape that also offers more ground clearance. There you’ll also find a dual-density downtube guard that uses a softer inner layer combined with a harder cap bolted on top, which can be removed for easier routing of the dropper post line.

The cables enter and exit in the usual places, but Yeti added little clamps at each of those points that gently hold them in place and should keep excess slack from shifting inside the frame. Other notables include a move to a threaded bottom bracket instead of Pressfit BB92, lots of rubber protection on the swingarm, and a relatively cheap and easy-to-find universal derailleur hanger.

Yeti has also changed a bunch of things in the suspension department with an eye toward reliability, most notably moving to press all of the bike’s bearings into metal suspension components instead of carbon front or rear triangles. This makes sense for all the obvious long-term and manufacturing reasons, but it’s also easier and less risky to remove and install bearings on a hunk of aluminum than expensive hand-laid carbon fiber. There are also new floating collet pivot shafts to hold it all together, and the Turq-series frames see better seals, bearings, and hardware used in the Switch Infinity slider unit compared to the C-spec frames that use the stuff from last year. .

What is all this about Turq and the C series? The two versions of the frame are built in-house and look identical on the outside, but Yeti says the Turq versions “are made from the highest quality carbon fiber available and offer the perfect balance of stiffness and compliance.” The C-series frames receive “small changes to the carbon fiber layup” that make them less expensive to manufacture, hence the slightly lower price for complete builds. Ride quality and frame stiffness are said to be identical, but the sleek SB140 Turq frame weighs in at 3.375 grams, 174 fewer than the peasant C version when both are fitted with the same Fox DPS shock.

suspension details

Some of us thought the new SB160 might use a similar six-bar design to the motorized E160, but Yeti stuck with a slightly revised version of the Switch Infinity slider design they’ve been perfecting for years. It’s the same story with the SB140, too, and that’s a good thing; We’ve always liked the balanced nature of the Switch Infinity for the way it’s always managed to do pedal and shock absorption jobs equally well.

Yeti has an interesting history with unconventional suspension designs, and if you’re unfamiliar with Switch Infinity, here’s the gist. The solid rear triangle floats on two links; The upper one drives the shock via a split fork and is pretty common, but not quite as low down on the bottom. That’s where you’ll see that the main pivot sits on a black anodized aluminum bracket that slides up and down on two Kashima-lined rails and a set of upgraded bushings. The grease ports allow you to inject a little love as needed without taking the whole thing apart, and Yeti also added better seals, bearings, and hardware.

What does all that do? “When the Switch Infinity reverses direction, the anti-squat drops dramatically for suspension freedom of movement,” explains Yeti, with the black rack sliding up on the two gold rails in the first part of the bike’s travel to get more anti-sink and better handling. feeling of power, before dropping back down later in the travel so the chain has less of an effect on the suspension action.

Geometry

Refinement continues in the geometry department, with a few small changes here and there, but also the notable shift to size-specific chainstays. While the previous version had a 433mm rear end across the range, the new bike is 2mm longer by size, starting at 436mm for the small and going up to 444mm for the double extra-large. The same goes for actual seat angles that start at 71.8 and go up to 77.3 degrees on the Lunch Ride version (slightly steep on regular models).

Lunch Ride builds get a 160mm-travel fork that places the head angle at 65 degrees, while less aggressive builds with 150mm forks sit at 65.4 degrees. Reach numbers range from 435 to 525mm, with a large 485mm seatpost and 623mm effective top tube length.
