The Yeti engineers are said to have spent ten years tinkering with the new wonder rear triangle – the six-bar linkage is designed to distribute forces even more effectively, provide greater control and have a positive effect on anti-rise and anti-squat. That’s the theory, at least.
First things first (travel, prices & weight)
The Enduro Yeti LT has 170 millimetres of front suspension travel and 160 millimetres at the rear – a true enduro bike. It replaces the two models, the SB160 and SB165. The platform is approved for a double-crown fork – though only up to 190 millimetres.
As usual, the prices are steep. Prices start at 7,400 euros for the Yeti LT 90; the top-of-the-range model costs 10,900 euros. The focus on lightweight construction remains secondary – the top-of-the-range model weighs in at a hefty 15.8 kilos (size M, All-29). The frame kit alone costs 5,400 euros.
The Sixfinity design in detail
Noteworthy: The shock now operates in a vertical position rather than a horizontal one. The Rocker Link controls the shock and connects the system to the Timing Link. This rotates around the pivot point of the Rocker Link and determines the direction of movement of the Switch Link. When the Switch Link moves upwards, pedal assistance is provided in the SAG range. A high anti-squat value ensures pedalling efficiency. When the Switch Link moves downwards, the anti-squat value decreases, creating scope for downhill performance.
The kinematics allow control over three parameters: acceleration (anti-squat), braking (anti-rise) and lever ratios. The individual parameters can be adjusted independently of one another to suit the intended use. Sixfinity distributes forces, resulting in greater structural strength and stiffness of the rear triangle throughout the entire travel. The architecture allows for the targeted selection of bearings without spatial constraints. The appropriate bearing is used at each pivot point.
Anti-squat and pedal efficiency
The anti-squat value can be precisely adjusted within the sag range. This is designed to deliver maximum efficiency from a ‘Pedal Anywhere’ setup and convert every watt directly into forward momentum. Sixfinity promises the same anti-squat characteristics as Switch Infinity. The system offers control over the progression and intensity of the anti-squat characteristics. At the same time, it provides greater flexibility in terms of anti-rise and gear ratios.
The anti-rise characteristics of the LT models are lower than those of their predecessor, the SB160. This is designed to ensure a balance between traction and maintaining geometry during braking. The anti-rise values remain constant throughout the entire travel. This means the Sixfinity is prepared for hard impacts under full braking load. The result is intended to deliver predictable handling and consistent performance in every braking situation.
Three progression levels via a flip-chip
The suspension’s progression can be adjusted between three characteristics by turning a flip-chip, without altering the geometry, anti-squat or anti-rise. The progression rates are 15, 20 and 25 per cent. Riders can choose between a constant, balanced or supple ride feel with increased bottom-out reserves. The linear characteristics of the curves are designed to ensure predictable handling.
Now also available with a storage compartment
The frame features an integrated storage compartment called ‘The Cavity’, with a CNC-machined locking mechanism and a spring-loaded latch. The dual-density cover with a wraparound rubber seal ensures a snug fit and a watertight seal. An internal divider and the Yeti frame bag keep tools, a inner tube and snacks safely stowed away. There are slots for AirTag and Tile trackers beneath the storage compartment.
Frame-size-specific chainstays
The geometry was developed through testing with Sixfinity prototypes. Longer, frame-size-specific chainstays are designed to ensure traction, riding stability and balanced weight distribution. The platform does not require specialised frames for MX or Dual-29 configurations. The chainstay lengths are 439 mm for Small, 442 mm for Medium, 455 mm for Large and 465 mm for XL. Riding characteristics can be adjusted with an additional 10 mm extension.
Wheel configuration and geometry adjustment
The LT can be switched between the Dual 29 and MX set-ups using a flip chip. An additional chip allows for a further 0.5 degrees of steering angle. When combined with the MX set-up, the bottom bracket height is reduced by 6 mm. The bottom bracket height is 350 mm in the 29-inch setup and 344 mm in the MX setup. Optional headset cups are based on the ZS44/56 head tube standard and feature integrated alignment marks.
The dropper post length is tailored to the frame size: Small 150 mm, Medium 180 mm, Large and XL 210 mm. Internal cables run through moulded carbon cable guides and are secured via Cable Capture ports. Combined with chain-slap protection, the bike remains quiet. An additional mounting point on the top tube provides space for fitting further systems.
Four model variants from 7,400 euros
- The LT X0 costs 10,900 euros and weighs 15.8 kilos in the 29-inch configuration. The MX version weighs 15.61 kg, according to the manufacturer.
- The LT XT Di2 costs 9,500 euros and weighs 16 kg. It features Shimano XT Di2 12-speed groupset, Shimano XT 4-piston brakes with 203 mm Freeza discs, DT Swiss E1900 wheelsets and a Crank Brothers Highline seatpost. An upgrade to DT Swiss EXC1700 EVO wheels costs an additional €1,200.
- The LT X0/90 costs 8,800 euros and weighs 16.1 kg. It combines SRAM 90 groupset with SRAM X0 crankset and cassette. The rest of the specification is the same as the XT Di2 model.
- The LT 90 costs €7,400 and weighs 15.99 kg. It features a FOX Performance 38 fork, a FOX Performance Float X shock, SRAM 90 groupset, SRAM Maven Base brakes with 200 mm Centreline rotors, and Burgtec Ride Wide Alloy handlebars with a 30 mm rise.
- All models are available in the colours TURQ and Nightout. Frame sizes range from Small to XL.
We’ve already had a go on the Yeti LT. You can read our first impressions on the website from 8 am tomorrow.
