Overview
The Yeti ASR is the lightest full-suspension bike Yeti has ever built, representing the brand’s most extensive carbon engineering project to date. With 115mm of rear travel paired with a 120mm fork, the ASR sits at the intersection of cross-country speed and short-travel trail capability. It uses Yeti’s Switch Infinity suspension platform — a translating pivot developed with FOX that moves vertically on rails rather than rotating around a fixed point. This design delivers exceptional pedaling efficiency under power while remaining active and sensitive on rough terrain. The ASR is available in five sizes (XS–XL) and runs 29-inch wheels throughout.

Geometry-wise, the ASR runs a 66.5° head angle and 75.5° effective seat angle across all sizes — numbers that are progressive for an XC bike but conservative compared to longer-travel trail machines. Reach ranges from 399mm (XS) to 490mm (XL), with size-specific chainstay lengths starting at 432mm and growing 2–3mm per size up to 442mm on the XL. The consistent 335mm BB height across all sizes keeps the center of gravity low for confident cornering. At approximately 21.2 lbs (frame and shock), the ASR is competitive with the lightest XC race bikes while offering more capability than a pure race machine.

Geometry Analysis
The ASR’s 66.5° head angle is progressive for an XC bike — steeper than modern trail bikes but slack enough to inspire confidence on technical descents. The 75.5° effective seat angle positions the rider efficiently over the pedals for sustained climbing, though it’s slightly slacker than pure XC race bikes like the Specialized Epic (76°+). The size-specific chainstay lengths (432–442mm) ensure consistent weight distribution and handling balance across the size range — a philosophy Yeti applies across its entire lineup. The 335mm BB height is low for an XC bike, which improves cornering confidence but means riders should be mindful of pedal strikes on rocky terrain. The 43mm fork offset provides balanced steering that’s quick enough for tight singletrack without feeling twitchy at speed.
Ride Characteristics
The ASR rides like a thoroughbred — light, efficient, and remarkably quick. The Switch Infinity suspension delivers a pedaling platform that rivals lockout-equipped designs, making the ASR a weapon on long climbs. But unlike a pure XC race bike, the 115mm of well-tuned travel gives the ASR genuine capability on rough descents. The short chainstays and low BB height make the bike feel nimble and playful in corners, while the 29-inch wheels maintain momentum over rough terrain. This is a bike that excels in XC racing, marathon events, and fast trail rides where every gram and every watt matters. It’s not the bike for charging the roughest enduro terrain, but for its intended purpose, the ASR is exceptional.
Key Specs
Frame: Carbon (Turq and C Series). Wheel Size: 29″. Travel: 120mm fork / 115mm rear. Suspension: Switch Infinity. Drivetrain: SRAM/Shimano (build dependent). Fork: FOX 34 SC. Shock: FOX Float. Sizes: XS, SM, MD, LG, XL.
What’s New vs Previous Generation
The ASR represents a complete ground-up redesign and is the most advanced carbon project Yeti has undertaken. The frame is significantly lighter than its predecessor while maintaining Yeti’s renowned durability. The Switch Infinity suspension has been refined for improved small-bump sensitivity and pedaling efficiency. The geometry has been modernized with a slacker head angle and longer reach compared to the previous SB115 it effectively replaces, while maintaining the XC-focused weight and efficiency targets.
Who Should Consider This Bike
The ASR is ideal for XC racers, marathon riders, and fitness-focused trail riders who prioritize climbing efficiency and low weight but want more capability than a hardtail. If you’re coming from a hardtail and want the lightest possible full-suspension upgrade, or if you race XC and want a bike that can handle technical courses, the ASR deserves a close look. Riders who spend most of their time on aggressive, rough terrain should look at the SB120 or SB140 instead.
Comparable Models
The ASR competes directly with the Specialized Epic, Santa Cruz Blur, Trek Supercaliber, and Pivot Mach 4 SL. All are lightweight XC/short-travel trail bikes with 100–120mm of travel. The ASR’s Switch Infinity suspension differentiates it from the single-pivot Blur and the Brain-equipped Epic, offering a unique ride quality that balances pedaling efficiency with bump compliance. The Trek Supercaliber uses an integrated IsoStrut shock design that’s even more race-focused, while the Pivot Mach 4 SL uses DW-Link suspension with similarly excellent pedaling characteristics.

Frequently Asked Questions
What is Switch Infinity suspension on the Yeti ASR?
Switch Infinity is Yeti’s proprietary suspension design developed in partnership with FOX Racing Shox. Instead of using a traditional rotating pivot, it features a translating pivot that moves vertically on precision-machined rails. This design provides a seamless transition through the travel — firm and efficient while pedaling, but active and sensitive over bumps — without the compromises of a conventional pivot.
How much does the Yeti ASR weigh?
The Yeti ASR Turq Series frame with shock weighs approximately 4.3 lbs (1.95 kg), making complete builds around 21–23 lbs depending on the component spec. This makes it one of the lightest full-suspension bikes available.
Is the Yeti ASR good for trail riding?
The ASR is primarily an XC bike with 115mm of rear travel, but its modern geometry (66.5° head angle, progressive reach) makes it capable on moderate trail terrain. For more aggressive trail riding with rougher descents, Yeti’s SB120 or SB140 would be better suited.
What wheel size does the Yeti ASR use?
The ASR runs 29-inch wheels across all five sizes (XS through XL). The 29er platform maximizes rollover speed and momentum — key advantages in XC racing and fast trail riding.
Does the Yeti ASR have adjustable geometry?
No, the ASR does not feature a flip chip or geometry adjustment. Its geometry is fixed, which is typical for XC-focused bikes where the priority is weight savings and simplicity rather than multi-position adjustability.
