The SB4.5 is the answer for riders looking for a versatile 29r 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.
Tested around the world by our friends at H&I Adventures as well as by our very own Bossman, Yeti president and owner, Chris Conroy, at the BC Bike Race, the SB4.5 TURQ frame got exemplary feedback. It proved light and capable and inspired confidence across rock gardens, rooty trails, and squirrely to smooth singletrack. The SB4.5 Carbon Series frames are 5.93 LBS (2.69 KG) and preserve performance at a more agressive price point.
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 rider feels perfectly balanced between the wheels not top heavy or lumbering.
Our Switch Infinity suspension technology allows us to eek more quality travel out of our suspension than other designs. As a result, the SB4.5 is not easily categorized until you ride it. Its a bit of a chameleon itll be whatever you want it to be. Our crew has raced it in seven-day epics, shredded it on high-alpine lines and its the go-to recommendation for someone who wants a versatile bike with big wheels. The SB4.5 is light and makes climbing feel effortless, yet takes on descents like a mini monster truck.
