SB5 Turq XX1 Eagle Complete Mountain Bike
Yeti Cycles' SB5 Turq XX1 Eagle Complete Mountain Bike brings your trail riding dreams into reality with its top-tier carbon construction and a build kit that's sure to garner more than a little attention at the trailhead. This SB5 gets the A-list treatment: DT Swiss XM 421 rims roll smooth and fast on its renowned 3500 hubs, and SRAM's superlative XX1 Eagle drivetrain offers up precise shifts and the ultimate 50t bailout gear. That mega cog is part of the storied XX1 cassette, a rare find on stock builds that boasts a Ti-Nitride finish to reduce shift friction and increase longevity over non-coated cassettes. The only non-XX1 piece is the crankset, which Yeti smartly trades out for the more trail-ready X01 Eagle carbon. It's still exceptionally light and stiff, but it has a hint of added reinforcement to better match the SB5's all-mountain capabilities.
This SB5 also carries Yeti's Turq designation, which represents the most advanced frame the company knows how to make. For the SB5, this means a more precise carbon layup, carefully molded to reinforce key stress points along the frame without adding any unnecessary bulk. This results in a frameset that has strength where you need it and much-appreciated weight reductions where you don't for a claimed weight saving of 350g compared to the standard SB5 Carbon.
The SB5's geometry is universally praised, meaning its plenty stable without missing out on nimbleness, thanks to its head tube angle sitting at an all-mountain appropriate 66.5-degrees. This pairs nicely with a slightly longer wheelbase and reach that combine for increased confidence when blasting through steep rock gardens. Conversely, the longer, slacker front end is tempered by a steeper seat tube angle and stiff, stubby rear triangle that keeps handling responsive and snappy as you deftly navigate tricky root systems and washed out trails.
The Switch Infinity suspension system is the key to the SB5's versatility. Switch Infinity offers a linear feel, while the eccentric link changes direction so you get excellent anti-squat properties for efficient pedaling and climbing. It rides unlike any other platform on the market because no other design can do what it does. The Switch Infinity slider travels upward under the first phase of compression when the SB5 is settling into its sag point. As the rear end compresses deeper, the direction changes and the DH-inspired slider travels down toward the bottom bracket shell to maintain a steady pedaling platform. This change of direction is smooth, and the transition is made without any harshness or spikes. Deep in the stroke, it works in conjunction with the upper pivot to produce a vertical wheel path that effortlessly flattens big, square-edged impacts.
