Disclaimer: I rode one day on this bike: I pedaled up Holy Jim and descended Upper Joplin, to Joplin, STT the Luge, Path Live Oak. back to Trabuco. Overall impression of the bike: Amazingly nimble and fun package. Fun and easy to manual, wheelie and hop. A solid climber and confident descender. Geometry and sizing of the large felt perfect for me at 5'10.5". 28.2 lbs as pictured with 3" tires, an amazing feat. 27.5+: On a FS bike – why? The reasons might be: 1) You like how it feels enough that the added rotating mass and bike weight is worth it. 2) You want to descend steeper terrain and want the added traction that makes it easier. 2) You want to ascend more technical terrain, and are willing/able to push the pedals harder. Plus tires are not for me. Up to 2.4 on the right rim that you can air down some covers my needs and wants from the most tech riding to flat bikepacking. A plus tire to me feels imprecise, a little noodly and sort of like a toy. No more confidence inspiring on tech DH that a 2.35, IMO. In some cases less. By the day's end the toll of the big meats was obvious – not what we need around the Santa Anas. Not interested in plus tires for any future hardtail projects. Don't want the capability in a frame, don't want Boost. For me there is no reason to ride plus tires. I will, however, try again with this bike. Eagle XO 12-sp drive worked as promised. I definitely need a normal granny gear to turn 3" tires, vs my 10-sp drive on my 2.3-tired Czar. This might be a great bike for some. It's a great execution of what it is/does. Plus capability kills it for me, and it's really just too much bike for the SAs IMO. The Tallboy is no doubt much better suited for around here. I'm much happier with my Czar and will be psyched to get it back. I felt like I was dragging an anchor today.
