The 2018 Yeti SB5.5 is available. We link to it on Competitive Cyclist above. While it has the same frame as the 2017 version we reviewed, there are a few component differences. We outline those below.
The Yeti is a great bike for shredding rough terrain, be it park laps or a big, burly climbs to the top of a bigger, burlier descent. While it's still fun on the soft, eroded folds of the foothills, it's not the best bike for those trails. Its true talents won't be tapped. It's a great choice for anyone hitting technical, challenging trails with any frequency. The Santa Cruz Hightower LT is more maneuverable, better on the big hits, and harsher on the small ones. The original 135mm Santa Cruz Hightower offers improved climbing and a marginally more playful attitude. The Hightower is still plenty capable but can get in over its head.
