yeti fahrradrahmen Yeti ASR T-Series Frame

When Yeti shelved the ASR, XC racing was a different discipline — smooth courses, pure watts, and bikes that prioritized weight above everything else. What brought the ASR back was the sport evolving into something that demands more: technical trails, punishing descents, and racers who need a machine capable of climbing efficiently and handling genuine mountain bike terrain. The Yeti ASR T-Series Frame is the answer — the lightest full-suspension platform Yeti has ever built, engineered from the ground up to compete at the world cup level.

The T-Series designation identifies this as a TURQ carbon frame, Yeti's highest-grade carbon specification. Reaching that standard required Yeti's most ambitious carbon engineering program to date: custom ply shapes, precision material selection, and intelligent draping methods that eliminate redundant carbon at every structural junction. Yeti's engineers used in-depth carbon analysis tools to remove solid volume at the pivots themselves, using existing tubing walls as part of each pivot's structure rather than adding dedicated material. This approach — two decades of carbon-only manufacturing experience applied at an unusually granular level — delivers a frame weight of 4.03 lbs without compromise to strength or bearing life. Every size gets its own carbon layup, tuned for consistent torsional stiffness and chassis-flex profiles across the range, so the XS rides like the XS should and the XL rides like the XL should.

The ASR's flex stay design has roots going back to 2003, when Yeti introduced one of the earliest flex stay XC platforms in the industry. The current version is a complete reinvention of that concept, updated to meet modern kinematic demands. With 115mm of rear travel and a near-linear leverage rate, the suspension is calibrated to stay efficient where XC racers spend most of their time — in the mid-stroke. Set 20% sag and small-bump sensitivity comes through at a level you'd expect from a bike with considerably more travel. The final quarter of travel ramps up deliberately, designed to handle bigger hits and aggressive race lines without deflecting off course. The SL rocker link — machined from billet 7075 aluminum alloy into a structural exoskeleton — contributes to weight savings while maintaining the rigidity that fast cornering demands.

The geometry reflects the kind of XC racing this frame is built for. A 66.5-degree head tube angle runs consistent across all five sizes — XS through XL — providing predictable steering whether you're threading a switchback climb or committing to a steep descent at speed. Seat tube angles range from 70.4 degrees on the XS to 72.1 degrees on the XL, placing riders in an efficient climbing position that transitions cleanly to standing sprints. Chainstays run 433mm on the XS, scaling to 441mm on the XL: tight enough for explosive acceleration, long enough to feel composed in rough terrain. The shortened seat tube accommodates proper dropper posts — XS and S frames support posts up to 150mm, medium frames up to 175mm, and L and XL frames can run 200mm or longer. That range matters on race courses that now include genuine descents.

Practical details add up across the build. The frame ships with a RockShox SID Luxe Ultimate 3P Remote rear shock — a premium baseline that most riders won't need to upgrade. Internally tunneled cable routing keeps the cockpit clean, while Hangerless Interface compatibility supports direct SRAM Eagle Transmission drivetrain mounting for maximum shifting precision. The included Universal Derailleur Hanger means any legacy or mechanical drivetrain works without adaptation. An integrated rear fender keeps mud and debris away from the suspension pivot on wet race days, adding virtually nothing to the frame weight. Two water bottle mounts inside the main triangle support hydration without an external cage, and a pivot-mounted chainguide boss keeps the chain in place on rough terrain without additional hardware.

Design Benefits

1. Zero redundant carbon: Custom ply shapes, precision draping, and pivot geometry that uses existing tube walls structurally — every gram of material is doing structural work, and nothing else.
2. Size-specific stiffness tuning: Each frame size receives a dedicated carbon layup calibrated for consistent torsional stiffness and chassis flex, delivering the same ride character regardless of which size you're on.
3. Efficient mid-stroke suspension: Near-linear leverage rate keeps pedaling energy moving forward through most of the travel range, with a progressive ramp in the final quarter to absorb drops and rough landings without deflection.
4. Hangerless Interface + UDH: Supports direct SRAM Eagle Transmission mounting for maximum drivetrain precision and shift accuracy, with the Universal Derailleur Hanger included for mechanical and legacy setups.
5. Integrated race-ready details: Built-in rear fender, dual internal bottle mounts, pivot-mounted chainguide boss, and internal shock lockout routing — functional features that add capability without adding weight.

Final Take

The Yeti ASR T-Series Frame is for riders who want to race — or simply ride — at the pace and on the terrain that XC has become. It's not a cross-country mountain bike in the old-school sense. It's a full-capability XC frame that happens to be exceptionally light, with suspension tuning and geometry that make technical trails feel manageable and smooth terrain feel fast. Pair it with a 120mm fork and a drivetrain that suits your ambitions, and you have the foundation for one of the most complete race builds available today.
