There are bikes you buy. And then there are bikes you commit to. The 2026 Yeti LT sits firmly in the second category.
Yeti has done something significant here — not an update, not a refresh. They've retired Switch Infinity after 12 years and rebuilt their enduro platform from the ground up around a new suspension system called Sixfinity. The LT replaces the SB160 in the lineup, carries the same 160/170mm travel spec, and costs more. So the question worth asking before you spend upwards of £7,899 is straightforward: why does it exist, what does it do better, and is it the right tool for where you ride?
That's what this Field Note is here to answer.
What Is the 2026 Yeti LT?
The LT is Yeti's long-travel enduro mountain bike. It runs 160mm of rear travel, 170mm up front, sits on a 64° head angle, and is built exclusively in TURQ Series carbon — there is no cheaper frame option, no aluminium version. What you're buying at every price point is the same chassis.
It is, by any measure, a serious enduro machine. Reach runs from 435mm (SM) to 510mm (XL). It's designed for riders who prioritise speed, traction, and composure on demanding terrain over snap and playfulness. Think steep Welsh slate, Scottish chunk & Alpine tech.
Quick reference:
- Rear travel: 160mm
- Fork travel: 170mm
- Head angle: 64.0° (63.5° in MX Slack mode)
- Seat tube angle: 77.5° effective
- Wheel size: 29" standard / MX (27.5" rear) compatible
- Chainstay: adjustable — 465mm or 475mm
- Frame sizes: SM, MD, LG, XL
- UK pricing: from £4,699 (frame) / £7,899 (90/X0 complete) / £9,799 (X0 AXS complete)
Why Sixfinity? And What Happened to Switch Infinity?
Switch Infinity ran for over a decade across Yeti's range. If you've ridden an SB150, SB160, or SB165, you know the slider link above the bottom bracket — the thing that made Yeti's suspension feel like nothing else on the trail. It worked. Riders loved it. So why change it?
Because Sixfinity can do things Switch Infinity never could.
Switch Infinity's slider mechanism was a four-bar system at heart. Clever, distinctive — but ultimately limited in how independently you could tune its behaviour. Change the leverage rate and you'd affect pedalling support. Adjust anti-squat and you'd shift braking sensitivity. The parameters were linked.
Sixfinity is a true six-bar system. Three additional links — the rocker link, timing link, and switch link — work alongside the main frame, chainstays, and seatstays to give Yeti's engineers (and ultimately, you) far greater freedom to tune the suspension independently. Anti-squat, anti-rise, and leverage rate can each be adjusted without dragging the others along for the ride. Its maths: more adjustability = more setting combinations.
The practical results on trail are worth noting:
More efficient pedalling without the braking sensitivity trade-off that typically comes with increasing anti-squat. More control over bump absorption through the mid-stroke. And a suspension progression you can actually tune yourself — not just accept as-is.
The other thing Sixfinity removes is the slider mechanism from the bottom bracket area. That freed-up space means longer dropper posts can run on larger frame sizes — a genuine quality-of-life improvement that the SB160 couldn't offer on some frames.
It's also worth understanding where Sixfinity came from. It wasn't designed for the LT. It spent over ten years being developed by Yeti including their eMTB platform — the 160E, LTe, and MTe — and was refined further through Yeti's World Cup downhill programme. The LT is the first purchasable analogue/ pedal-only bike to run it. That pedigree matters.
The Adjustment System: More Than Just Flip Chips
Before buying any adjustable bike, it's worth understanding which adjustments are genuinely meaningful and which are marketing noise. On the LT, they're all meaningful. Here's how to use them.
Suspension Progression: 15% / 20% / 25%
A flip chip at the lower shock mount changes how the rear suspension progresses through its travel. This is not a minor tweak.
15% progression — the most linear setting. The suspension stays active and sensitive deep into the travel. If you're a lighter rider, ride smoother or more varied terrain, or prefer a plush feel throughout, start here. Works well with a lighter air spring tune.
20% progression — the middle ground. Balanced support and sensitivity. Most riders will land here as a baseline and adjust from there.
25% progression — the firmest ramp-up. The bike holds higher in its travel and resists bottom-outs more aggressively. For heavier riders, particularly steep or rough terrain, or if you want a higher-volume air spring setup, this is your setting.
Combine this with Yeti's custom in-house shock tuning (every LT shock gets individual shim stack work from Yeti's R&D team) and you have a rear end that can be genuinely dialled rather than just approximated.
Chainstay Length: 465mm or 475mm
Interchangeable rear dropouts let you shift between two chainstay lengths. This changes the handling character of the bike in a way you'll feel immediately.
465mm suits riders who want more front-wheel engagement on climbs, tighter cornering, and a more nimble feel on switchbacks and technical singletrack.
475mm pushes more weight rearward, increases high-speed stability, and gives you more confidence when the terrain opens up. If you ride enduro stages or spend time in the bike park, start here.
On larger frame sizes (LG and XL), the LT's chainstays are notably longer than the SB160's were — this is a deliberate design choice to improve stability and fore-aft balance for taller riders.
Wheel Size: 29" or MX (27.5" rear)
The LT runs a flip chip that lets you switch between full 29" and MX (mixed wheel (aka Mullet) — 29" front, 27.5" rear) with zero geometry compromise. Yeti has engineered the kinematics so that switching wheel size doesn't change your head angle, reach, or bottom bracket height. You're not making a sacrifice, you're making a choice.
When to run 29": More rollover, more momentum, better on open and fast terrain. If you're racing enduro stages or riding big mountain trails, this is likely your setup.
When to run MX: More agility in tight tech, a slightly lower feel on the bike, better for shorter riders or those who prefer a more manoeuvrable character. The 27.5" rear also makes it easier to run a heftier tyre casing on the back.
There's a secondary Slack chip specifically for MX mode — it drops the bottom bracket by 6mm and slackens the head angle by a further 0.5° (to 63.5°). If you're running MX and riding steep, aggressive terrain, it's worth using.
TURQ Carbon and Why the Frame-Only Makes Sense
Yeti makes the LT exclusively in TURQ Series carbon. This is their highest-grade layup, reinforced with Vectran — a liquid-crystal-polymer fibre used in aerospace and marine applications — for impact resistance that holds up to enduro riding. The frame is not light-optimised at the expense of durability. It's built to take hits and stay stiff where stiffness matters.
It also features The Cavity — an integrated downtube storage compartment with a CNC-machined roller-cam door mechanism and rubber gasket. It holds a spare tube, multi-tool, tyre plugs, or a layer. Weight stays low and central. Pockets and packs stay lighter.
The frame-only option at £4,699 deserves serious consideration for two types of rider:
One, those upgrading from another bike with components worth keeping — quality Fox or RockShox suspension, a premium drivetrain, and good wheels don't need replacing just because you want a new frame.
Two, those who want to spec the LT exactly as they want it, rather than accepting compromises in a complete build. The frame ships with a Fox Factory Float X2 shock — custom tuned by Yeti — so the foundation is solid. Build from there.
LT vs SB160: Who Should Make the Switch?
The SB160 was a well-regarded enduro bike with a loyal following. If you're on one now and wondering whether the LT is worth the investment, here's the honest guidance.
The LT is a different bike, not just a better one. It's longer in the rear, taller in the stack (+15mm), and meaningfully more adjustable. The Sixfinity suspension delivers a ride that's calmer and more controlled at speed than the SB160 — particularly on rough, steep terrain where the SB160 could feel busy.
What you trade is the SB160's snap and nimbleness. The LT is a bike that rewards commitment. Point it at something frightening, carry speed, trust the traction — that's where it comes alive.
If you pushed the SB160 on long enduro stages, found yourself wanting more stability at speed, or ride the kind of terrain where traction and composure matter more than flicks, the LT is the natural evolution.
Which Build to Choose
All three LT builds share the same TURQ Series frame and Fox Factory suspension package. The differences are in drivetrain, wheels, and brakes.
LT T-Series 90/X0 Factory 29" — £7,899 The entry point, and a strong one. SRAM X0 components throughout on a mechanical Eagle 90 drivetrain. DT Swiss E1900 alloy wheels. SRAM Maven Silver brakes. If you want the LT platform and you're happy to run cables, this is a complete, capable bike with nothing soft in the spec. The platform for most riders.
LT T-Series X0 AXS Factory 29"/MX — £9,799 Everything above, plus SRAM X0 AXS Transmission — fully wireless, no cables, instant shifting under load. DT Swiss EXC1700 carbon wheels (notably lighter and stiffer than the E1900 alloy). For riders who want the absolute best spec on the frame, or who are coming from a wireless system and don't want to go back, this is the build. The MX compatibility also comes as standard in the name of this build — 27.5" rear-ready out of the box.
LT T-Series Frame Only (29"/MX) — £4,699 Fox Factory Float X2 included. Bring your own build. For experienced riders who know what components they want and aren't prepared to compromise on. As noted above — if you have a quality component inventory already, this is the most efficient path to the LT.

Who the LT Is For
After all of this, the LT is a bike for a specific type of rider. Not every rider. Being clear about that matters.
You'll get the most from the LT if you ride enduro, technical all-mountain, or bike park terrain where stability and traction at speed are the currency. If your rides include steep chutes, rough descents, big EWS-style stages, or the kind of terrain where your previous bike was making you nervous before you wanted it to — the LT is a direct answer to those problems.
It's a bike that asks you to commit. In return, it delivers composure that few 160mm bikes can match, a suspension system that is genuinely tuneable rather than just adjustable in name, and a chassis that will not be the limiting factor in what you're capable of.
The limit, as Yeti put it, is you.
The Bottom Line
The 2026 Yeti LT is the most technically sophisticated enduro bike Yeti has built. Sixfinity is a meaningful step forward — not a marketing refresh — and the LT's adjustability gives you real tools to tune the bike to your terrain, your weight, and your riding style. If you're in the market for a serious long-travel enduro bike the Yeti is an excellent option at the leading edge of enduro bike capability.
