The 2023-on SB140 29 marks a meaningful reset for Yeti’s mid-travel trail bike rather than a simple wheel-size change from the earlier SB140. It keeps the brand’s 140mm rear-travel Switch Infinity layout, but wraps it in a substantially updated chassis with a threaded BSA bottom bracket, SRAM UDH compatibility, revised internal routing aimed at reducing noise, improved frame protection, and updated Switch Infinity hardware and sealing. That matters because the new bike addresses several ownership and serviceability complaints associated with older Yetis while bringing the frame into line with current standards.

In the market, the SB140 29 sits between lightweight trail bikes and mini-enduro machines. Its intent is broad: a do-it-all trail platform that can cover long technical rides, aggressive descending, and faster all-mountain use without drifting into full enduro territory. Yeti’s design brief leaned toward a more modern but not extreme fit, with a steeper effective seat angle and size-specific proportionality concepts to keep rider balance consistent across the range. The result is a bike defined less by brute-force plow behavior and more by precision, efficient suspension support, and a notably refined chassis feel.

03 / Geometry

Geometry & fit.

5 sizes published.

The available geometry points to a modern but relatively balanced trail-bike fit rather than an ultra-slack mini-enduro layout. Across the size range, the head angle is 65 degrees and the seat angle is 77 degrees, with reach numbers of 429.3mm (S), 459.7mm (M), 480.1mm (L), 505.5mm (XL), and 520.7mm (XXL). On the common Large size, the 624.8mm stack and 480.1mm reach create a roomy but not extreme cockpit, while the steep seat angle helps center the rider for seated climbing. Review feedback matches those numbers: the bike places riders in a strong pedaling position, but the relatively low stack can make the front end feel low on steeper terrain unless cockpit height is adjusted.

Handling is shaped by Yeti’s size-specific rear-center lengths, which grow from 436.9mm on S and M to 439.4mm on L, 442mm on XL, and 444.5mm on XXL. That should help preserve front-to-rear balance as the frame gets longer, rather than leaving taller riders with an overly short rear end. Wheelbase grows from 1188.7mm in S to 1303mm in XXL, reinforcing the bike’s stable-at-speed character without pushing it into cumbersome territory. In practice, these numbers suggest a bike that should feel quick to place and easy to generate speed on, but one that asks the rider to stay engaged and weight the front wheel, especially on steep climbs and descents.

The lineup.

6 builds, ranging $6,200 – $11,000.

The SB140 29 is offered in a broad spread of builds, ranging from C-series carbon completes up through top-end Turq models. Listed builds include T1 XT Di2, T4 XX AXS Transmission, T3 X0 AXS Transmission, T2 X0/90 Transmission, C2 90 Transmission, and C3 GX AXS Transmission. That lineup gives buyers clear entry points depending on whether they prioritize the lighter Turq frame and premium electronic drivetrains or want the same core platform in a less expensive package.

From review coverage, the C-series builds are generally seen as the more rational buy because they retain the same geometry and suspension character while avoiding some of the steepest pricing attached to the Turq models. At the top end, reviewers consistently praised the suspension quality and overall frame refinement, but several criticized the value equation, arguing that some expensive builds still look conservative on paper for the money. In other words, the SB140’s build range offers real choice, but the strongest case is usually for riders buying into Yeti’s frame and ride quality first, rather than chasing the most aggressive spec sheet per dollar.

05 / Reviews

From the press.

21 reviews from the cycling press.

Reviewers are largely aligned in describing the SB140 29 as one of the more sophisticated-riding bikes in the mid-travel class. Much of that praise centers on the revised Switch Infinity suspension, which multiple testers said combines unusually firm pedaling manners with a deep, plush feel once the trail gets rough. Out on the trail, reviewers repeatedly noted that the bike climbs with very little need for shock lockout, carries speed exceptionally well over broken ground, and feels more capable than its 140mm rear travel figure suggests. MBR called it a brilliant pedaller and a true one-bike solution, while Bike Perfect highlighted the bike’s unusually balanced handling and suspension performance. Several reviewers also praised the quietness of the frame, citing the improved cable routing and frame protection.

On descents, the SB140 was consistently characterized as a precise, poppy, speed-generating trail bike rather than a point-and-shoot plow machine. Testers from outlets including Off-road.cc, Bike Perfect, and others found that it rewards an active rider who pumps terrain, commits to corners, and keeps weight on the front tire. That same trait produced the main criticisms. A recurring complaint was the low front end and modest stack height, which some testers felt made the bike feel too low or stretched on steeper trails; higher-rise bars were a common recommendation. A few reviewers also noted that the rear suspension can need careful setup to deliver enough support in G-outs or hard compressions, and several pointed out that the premium pricing does not translate to standout value on a pure spec-per-dollar basis. There is strong admiration for the ride quality, but also broad agreement that this is a premium, somewhat demanding bike rather than an easygoing bargain.
