The SB4.5 is the answer for riders looking for a versatile 29’r rig. The SB4.5 frame design is optimized for 29″ wheels and has a distinctly different personality than 29ers of old, ensuring the rider feels perfectly balanced between the wheels – not top heavy or lumbering. The proficient Switch Infinity suspension platform and short chainstays make this bike feel effortless on climbs and lively and plush on descents.
For a bike that so clearly excels at climbing, the SB4.5 is incredibly balanced, its longish top tube and sensibly slack 67.4-degree head angle instill confidence on challenging descents. Coupled with an optimal chainstay length and Switch Infinity suspension the SB4.5 feels more capable that a traditional 4.5” travel bike. The new Eagle drivetrain with a 10 to 50 cassette provides a wide range of gears in a convenient one-by system.
In far-flung spaces or at your local trails, the sb4.5c is built for adventure.
