Yeti found the sweet spot with 29-inch wheels and 4.5-inches of travel in the trail-ready SB4.5. Thanks to Switch Infinity suspension, the SB4.5 lets you push beyond what you think a 4.5-inch travel bike should do, encouraging fun through its lively ride qualities. From marathon XC pursuits to hot-laps on your local trails, the SB4.5's stiff carbon frame, short chainstays, and comfortably slack head angle work together to put you in the best position for sprinting up climbs and railing descents with confidence. The GX build brings SRAM's workhorse 12-speed drivetrain paired to Guide R brakes for performance you can count on without breaking your budget. Fox Performance suspension components maintain the build's get-it-done sensibility, and a Transfer dropper seatpost aids your aggressive antics with instant response. 29-inch DT Swiss wheels provide great rollover clearance; paired with Maxxis Ardent tires you'll find yourself carrying more momentum up, down, and over everything that comes your way. More momentum equals less effort, and less effort means bigger grins. We'll call that a win.
