Overall Review:

Since 1985, Yeti Cycles have been in the business of creating some of the most competitive mountain bikes in the industry. The company has changed their main focus from XC to DH and is now set out to dominate the Enduro Racing series. The Yeti SB66 frame was the frame that opened the worlds eyes on whats possible on a "trail bike" and is the forefather to Yeti's latest enduro masterpiece, the SB6c. The capabilities of the Yeti SB66 are something that the world have never experienced, dominating podiums in the Enduro series and well as a podium position in the World DH series (2013 UCI Downhill World Championships in Pietermaritzburg, South Africa.) Not too many frames hold such a impressive reputation in terms of capabilities. Will all this being said, here is my review on my Yeti SB66 which was owned for 2 years.

2013 Yeti SB66 (Custom build)

As you can tell, this bike was completely custom and isn't anywhere close to stock. From a full Saint groupo to a 170mm Rock Shox Lyric and Canecreek DBair, this bike was more of a mini DH bike rather than the everyday trail bike. Weighing in right at 32 lb, it wasn't the lightest bike to hit the trails either. The most important thing was that it was built to hit my purposes, exactly. 

While Riding

Pedaling was very easy considering the added weight of the overbuilt components. With the 26" wheel platform, the bike had no problem keeping up with other bikes in it's class during it's glory years. There was a noticeable difference when turning the climb switch on the DBair as well which helped with the more vertical climbs. In short, the Yeti SB66 did an alright job while climbing compared to other bikes in it's class. What the bike is capable of when coming back down is really what makes this bike stand out above the rest.

Draper DH Trail, Utah.

Once you have reached the top of the climb and it's ready to ride back down, the Yeti SB66 changes into a completely different animal. It bits, chews, and spits out anything you feel comfortable enough to put in it's way. After owning a few DH bikes, I got the Yeti SB66 frame to allow me to pedal but still be able to ride many of the trails I used to while on the DH rigs. This is exactly what I was able to do as well. The patented Switch Technology allowed the the bike to run smoothly through it's travel and created a "bottomless" feel while riding the roughest parts of your favorite trails. I noticed this while riding lift runs at the Canyons and Deer Valley resorts. There are a few times that I honestly felt that the Yeti SB66 handled bottom-outs better my Session 9.9. No wonder why Jared Graves was able to podium on the Worlds DH series on this his SB66.

Maintenance

With the Switch Technology (which allows the linkage bolt to pivot around oversized bearings) would seem to require endless maintenance after each ride but Yeti has done an exceptional job in protecting this new technology from dirt and water. I would completely overhaul my linkage about ever other month (yeah, I'm pretty OCD) which is actually less frequent than I had to do with my other bikes, like the Trek Slash. I was very impressed with how easy it was to clean and put back together as well. Don't let the fear of maintaining this high-end bike stop you from picking one up, This is true for the SB66 as well as the next generation switch technology found on the Yeti SB6c.

Complaints

My only complaint with this frame is that it is slightly heavier than other trail bike frames. The bulk of this weight is due to the casing to house the Switch Technology pivot point. The Yeti SB66 carbon frame is significantly lighter in weight but is still on the heavier side of carbon frames. The latest version, the Yeti SB6c, is much lighter which makes it a lot more competitive for true all-mountain riders.

Bottomline

The Yeti SB66 was a pioneer in proving what trail bikes are capable of. That being said, there were two things that could have been improved on in this competitive industry. The first one was weight. The second is the almost over-night evolution of the 650b platform. If neither of these are a deal-breaking issue for you, I would recommend you grab a close out frame or get a used frame while they are still available. I'm sure you'll be able to find one for a phenomenal deal. I would recommend this frame to anyone who wants a great performing frame without spending thousands of dollars for the latest and greatest.
