SB5+ T-Series GX Eagle Complete Bike
Yeti Cycles has always had a penchant for going big, with each generation of SB getting slacker and longer while eking out every last millimeter of travel. The SB5+ T-Series GX Eagle Mountain Bike goes a step further, adding plus-sized wheels to the ever-expanding menu of ever-expanding dimensions. It's not as light as its non-plus counterpart, sure, but the floating traction and pneumatic suspension of plus-sized tires means the SB5+ can venture boldly into chunky terrain and loose conditions that the standard model would balk at. It's a trail bike that can handle virtually any trail, and we built it up with SRAM's equally redoubtable GX Eagle group and Guide R brakes, a combination that ensures you'll always have the climbing gear and the braking precision required to push the SB5+ to its limits.
The SB5+ features some geometry tweaks that enable it to ride as a true plus-bike, with ample tire clearance for 3in tires to dominate loose banked corners and precarious rock gardens. While overall frame geometry stayed quite consistent between the SB5 and the SB5+, it's notable that the rear triangle saw a major redesign with elevated chainstays that allows for increased rigidity and tire clearance. Still maintaining short and snappy a rear end, the elevation of the chainstays simply takes them up and out of the way with an arc that increases clearance space while keeping the stays at 17.2-inches for quick power transfer and nimble handling.
Staying close to the rear end, you'll find the switch infinity rear suspension design that effortlessly transitions through travel for a buttery-smooth ride. With a translating pivot it switches directions to move through your travel as you ride, maximizing anti-squat characteristics so you don't lose power in your pedal stroke. The linear path of the system moves with little resistance, allowing small bump sensitivity and pedaling efficiency in the beginning of the travel, but soaks deeper when further into the travel to take square edge hits and drops with ease. FOX's Performance DPS rear shock makes for 5in of play-ready suspension hungry for techy tree lines and rock gardens. And for those gnarly and steep tree lines, Yeti's engineers set you up with a slacked out 67.1-degree head tube angle that feels planted and bombproof, with confidence inspiring geometry that's eager to devour the descents.
A complete package should pair a high performance frame with the top level materials, so Yeti offers the SB5+ frame in their high-modulus Turq carbon fiber. Weighing in at a miniscule 5.34lbs, the frame has a flawless balance between compliance and stiffness, with reliable manufacturing techniques that lead to minimal resin pooling, strong joints without excessive materials, and unsurpassable durability. Turq level carbon is the cream of the crop, and on the SB5+ it feels smooth, solid, and aggressive as it tackles every trail you point it down.
