Thanks. I am very pleased with the bike so far. The rollover is just amazing. I had the pressures up around 22 to 25 pounds (wanted to make sure they were sealed up good and didn't want to have to walk home) so I know I didn't get the full traction benefit. But with that, it didn't feel like sluggish or slow at all. After trying the WTB Trailblazers on my 062 frame, I knew I wanted to have a dedicated plus bike for winter / crappy weather riding. I also wanted something with great "rollover" capabilities as one of the riding areas next to my house is full of rocks and roots and there is ZERO flow or buffed trails as you can see in one of the pictures. Carbon_Dude, I wouldn't say that a new wheelset for converting an existing frame to 27+ is a waste of money but if the bike budget allows, just go for the dedicated 29+. You won't be disappointed. And with the higher tire pressures, I really couldn't tell much difference in handling vs my rigid 062 bike.
I guess that 29+ is the way to go if you want full rigid. And this bike is just awesome. The only point I don't like is the cable routing of the rear derailleur (out of the frame in the middle).
Then, I still believe that 27.5+ is better for hard tail or short travel full.
As far as rigid vs HT vs FS, I would have to agree with some members on MTBR. For rigid and HT, if you can comfortably fit on a 29+, don't waste your time on a 27+. And yes I've ridden a 27+ rigid bike. The benefit over a standard 29er is there but it just isn't that much of one. Now for a FS bike, I would have to stay with 27.5 x 2.3ish tires on 30mm internal rims. I'm not sure yet if it's worth the weight penalty when traction isn't an issue in the standard format. The nice things is that there are SOOO many options right now and it's only getting better.
The cable thing is just an unfortunate necessity. There really isn't any other way to do it other than dropping the stay to the normal level and keeping it internal which also makes the CS's longer, or just use the cable stops that are pop riveted on but those are just ugly IMO.
