300 km road and off-road test of the new Yeti LT 2027 with Sixfinity kinematics: real scale weight, six-bar linkage analysis, and dynamic comparison across climbs, descents, and flats..
AT A GLANCE (QUICK SPEC SHEET)
The verdict in one sentence: The Yeti LT 2027 marks a monumental shift by retiring the Switch Infinity in favor of the new six-bar Sixfinity design, evolving into an Enduro/Gravity monster that offers unprecedented ground tracking and complete bottom-out control.
Key takeaways: New Sixfinity kinematics with independent management of anti-squat and anti-rise, 170 mm front / 160 mm rear travel with adjustable leverage progressivity (15%, 20%, 25%), and integrated The Cavity storage compartment inside the TURQ carbon frame reinforced with Vectran.
Who it's for: Enduro racers, bike park enthusiasts, and advanced riders seeking an aggressive race weapon featuring ultra-modular geometry to push the limits on the most extreme mountain lines.
When the team in Golden, Colorado decides to retire their iconic Switch Infinity platform to debut the all-new Yeti LT 2027, the Enduro world witnesses a true conceptual revolution. The new Yeti LT moves away from vertical linear translators to embrace the brand-new six-bar Sixfinity layout, an architecture engineered to isolate pedaling forces, braking squat, and the shock's leverage rate.
To determine whether this complex kinematic platform represents a genuine performance leap under heavy abuse, we skipped the standard press camps. We put it through its paces over nearly a month, logging 300 real-world kilometers and over 3,500 meters of elevation gain across the most brutal Alpine rock gardens, DH tracks, and fast valley liaison roads.
Lab & Scales Data
Claimed figures in technical sheets only tell half the story. Unboxing the bike, we placed it straight onto our precision workshop scale. In size L, built with the TURQ frame, SRAM X0 Transmission spec, tubeless sealant, and an empty The Cavity compartment, the Yeti LT in 29" configuration weighed in at 16.30 kg (including pedals).

Uphill: Responsiveness & Power Transfer
Even though this is a heavy-duty 170/160 mm platform carrying noticeable mass, its ascending performance is surprisingly efficient thanks to the Sixfinity layout. The high anti-squat value around the sag point keeps the rear shock propped up, eliminating pedal bob even when stomping hard on the pedals.
On steep pitches exceeding an 18% gradient, the steep 77.5° seat tube angle shifts your hips forward, loading weight over the bottom bracket and keeping the front wheel glued to the ground. On technical, rocky ascents, the rear end works completely neutrally: it doesn't wallow, offering surreal traction to clear tricky obstacles without needing constant torso corrections.
Downhill: Front-End Precision & Cornering
Once the trail points down and gravity takes over, the Yeti LT reveals the true superiority of its six-bar system. Rear wheel tracking is incredible: low anti-rise keeps the rear suspension fully active and independent of braking forces, delivering insane grip during heavy deceleration.
High-Speed & Heavy Impacts: The TURQ carbon frame with Vectran provides controlled flex that damps high-frequency chatter while delivering rock-solid high-speed stability. On big drops and potential bottom-outs, Sixfinity's progressive curve holds up the ride height, preventing harsh clunks at full travel.
Tight Turns & Handling: The wheelbase is long, but shortening the rear-center to 455 mm via the modular dropouts makes the bike surprisingly nimble through quick directional changes and tight switchbacks, perfectly balancing the 485 mm reach.
Braking Performance: Pairing SRAM Maven Silver calipers with HS2 rotors delivers monstrous stopping power with minimal finger effort, completely eliminating brake fade on long, steep descents.
Flats & Rolling Terrain: Efficiency & Energy Conservation
On flat liaison sectors and fast gravel connectors between trailheads, the rear end remains "shockingly calm".
Straight-line stability is exceptional, and the smooth rolling resistance of the Schwalbe Radial tires paired with DT Swiss EXC 1700 carbon rims allows you to maintain a steady cruising speed. The integrated The Cavity compartment lets you pack a tube, pump, wind jacket, and tools in a fully insulated space that remains 100% rattle-free over rough terrain.
Yeti LT 2027 vs. Yeti SB160 (Switch Infinity): Is it worth the upgrade?
Moving from Switch Infinity to Sixfinity is a major architectural shift. Here are three concrete reasons why the upgrade makes sense:
Independent Kinematic Tuning: Sixfinity lets you adjust leverage progressivity (15%, 20%, 25%) to match the terrain—something impossible on the previous generation.
Uncoupled Braking: Anti-rise management prevents the rear end from stiffening under heavy braking, keeping the rear tire locked to the trail.
Integration & Modularity: The addition of The Cavity internal storage and adjustable dropout lengths (up to 465 mm) delivers true World Cup race tuning.
Pros & Cons
Pros:
Sixfinity system: flawless isolation between pedaling, bump absorption, and braking.
Ultra-solid TURQ/Vectran carbon structure that feels precise and completely silent.
Industry-leading geometry modularity (progressivity, flip-chip, chainstay length, and mullet compatibility).
World-class downhill performance and big-hit absorption.
Cons:
High mechanical complexity of the 6-bar system (requires precise torque settings and mechanical know-how).
Significant overall weight (16.30 kg ready to ride).
Accessing an AirTag/Tile tracker placed under The Cavity requires removing the storage tray.
