About this product

The Yeti Cycles SB140 TURQ 29in Mountain Bike Frame is built around the brand's Switch Infinity translating pivot suspension platform, delivering 140mm of rear travel tuned for aggressive trail riding and big mountain terrain. The frame is constructed from TURQ carbon fiber, a layup that balances stiffness, compliance, and durability while keeping claimed weight to just 6lb 5oz (2863g). A Fox Factory Float X rear shock is included, providing supportive, tunable performance with sensitivity across the full travel range. A patented compact wishbone shock extender optimizes the leverage rate and improves standover clearance. Internal cable routing with guided tubes minimizes noise and cable rub, while a threaded bottom bracket simplifies drivetrain maintenance compared to press-fit alternatives. The frame accepts tires up to 2.6in wide on 29in wheels, uses a 12x148mm Boost rear axle, and features ISCG-05 tabs, a tapered head tube (ZS44/ZS56), and a 31.6mm seatpost diameter. Universal Derailleur Hanger compatibility eases trailside repairs. The frame carries a limited lifetime warranty, with a separate one-year limited warranty covering paint and finish.

What people are saying

Reviewers consistently praise the Yeti SB140 Turq 29 for its exceptional suspension performance, describing it as active yet supportive with outstanding small-bump sensitivity and phenomenal traction in corners. The Switch Infinity platform earns repeated credit for decoupling drivetrain and suspension forces, making the bike feel planted and confidence-inspiring on descents while remaining agile and fun on climbs. The Turq carbon layup is noted for being size-specific and lightweight, and the frame is backed by a lifetime warranty. The most common criticisms center on the steep price, with some reviewers noting that component specs feel slightly behind competitors at the same cost. A few testers also flag that the frame lacks internal storage and feels feature-light compared to newer rival designs, and the Switch Infinity link has a historical reputation for requiring attentive maintenance, though the updated Turq knuckle design has largely addressed this concern.
