Yeti continues to adapt along with the rest of the mountain bike industry to the Boost hub revolution and the SB5.5 is the crown jewel in my opinion. I first had a chance to ride this bike at a Yeti demo last summer and was extremely skeptical going in. The Santa Cruz Hightower had been my favorite bike of 2017/18 but let's just say that was before ripping on the SB5.5. I have now been on this bike a handful of times, both in the mountains of Park City and the desert of Moab, and it continues to impress me for a variety of reasons. The only comparable bike out there is the new Hightower LT.
Quick note: This is the Turq -Series frame that is slightly lighter compared to Carbon series frame from Yeti (only available on complete bikes). I have ridden both frames and can't tell the difference. Also, the key upgrade on the SB5.5 for 2018 is the FOX Float X Factory.
There are a couple key differences between the Hightower and SB5.5. The SB5.5 has a slightly steeper head tube angle (66.5 degrees), slightly higher BB height and longer wheel base. But truth be told the key for me is that a Large Yeti just fits me better than a Large Santa Cruz. I am 6'1" with pretty long arms and for whatever reason I have always felt that Large Santa Cruz bikes are too small (and XL too big). But the Yeti SB5.5 in a Large was built just for me.
I was most impressed with how easily it plowed over everything put in front of it. If there was a plowability rating I would give it 6 stars out of 5. It handled steep, technical terrain with ease and cornered surprisingly well for a 29er considering the added lateral stiffness from the wider Boost hubs. This bike had solid pop off of jumps and was smooth in the air which I did not expect but should not be surprising considering the tech behind the Switch Infinity Link.
If you are looking for a new super bike and are considering the Yeti SB5.5 do not hesitate to reach out to me with any questions. I would be glad to help you build this bike from the frame up.
