So I haven’t done much biking in the last 7 or so years. But I’m liking to look of the new plus size 27.5 hard tails. Norco fluid ht, rocky growler, trek roscoe, any others I should look at? I definitely want a dropper post. And local shops with good deals going on?

I also hear good things about the Stache 9.7, or get a Chromag Rootdown and put 27.5 wheels on it...fun bike!

So 27.5+ is basically 29”, same frames and forks?

Correct... with most brands/models.

Take a look at the Salsa Timberjack, with the alternator dropouts you can run any drive train you want, everything from SS to a roloff hub or just change the WB

Usually. They're about the same radius, but there can be some tire width clearance issues on some frames. For example the Kona honzo with 29" does not fit 27.5+, but the Big honzo has wider slightly longer chainstays and does. If its a 27.5+,it should take 29", just maybe not the other way around. Pretty much all 29" forks will take a 27.5+. Double check with frames.

In additon to the Kona mentioned above, take a look at the Commencal ht/am, and Marin San Quentin.

From looking at the various tire option, not all 3.0" tires are the same inflated width, the same goes for 2.8".  The Specialized Slaughter 2.8" seems to be the ideal option for people running 29" frames that were designed pre-27+ as they tend to fit a bit better.

Side note, I picked up some Sun Ringle Duroc 50 wheels and Spec. 3.0 tires to mount this winter, just haven't gotten around to converting my E29, which is 27+ compatible.  I'm going to try and find some time tomorrow and go out to test it. Now that I have a hitch mounted rack, things should fit a bit better (previous roof rack mount was not 27+ compatible).

Pretty eager to see if there is an increased fun factor to running the + tires.

My 27.5 evil has a boost fork and room for a 2.5 or more in the back. I figured I'd try some fatter tires this winter. I don't think the plus thing is for everyone. I haven't rolled a Tire to the point of air leakage in a while. 2nd ride I did it doing something I do all the time on the trail. I personally wouldn't recommend investing in any bike in order to run it plus. If your bike fits fat tires, great. But plus is for beginners I think. As soon as you start going faster or railing your corners harder, the Tires peel from the rim. My usual tires at 2.4 are a harder casing that keeps shit tight. In order to make a huge tire not too heavy it is made with wimpy sidewalls that fold under pressure.

Just my 2 cents. But not going plus means you can look at way older stock and get an amazing deal because it's "old technology"

Um... tires won't peel from the rim if you have rims designed for plus sized tires. And I also seriously doubt plus is for beginners. I have a 2018 Ibis Mojo 3 with boost axle spacing and room for 2.8 tires. Currently I have 2.6 Maxxis Minion DHF's front and rear running at about 20lbs of pressure. The rims are from Ibis and have an internal width of 34mm and combined with the 2.6's the traction and handling is amazing.

I believe Ibis really thought out the plus-sized tire option. The rims they manufacture and include in their builds really take advantage of what a plus sized tire can provide, and the current offering of plus sized rubber is pretty awesome too - I think.

I've got Stan's MK3 flow rim with a 2.5 aggressor tire on the back and it was burping. Maybe its the wrong set up or maybe I'm too big. I don't know. All I know is that my 2.4 tires never burp and I ride them much harder. The traction is fine but at speed I don't find the bigger tires are as stable. Out of curiosity, how many enduro pro riders are riding 2.6 and 2.8 tires?
