It's interesting to read everyone's opinon on the difference between normal and + tires. Not sure if I even qualify with all the hoopla surrounding the WTB trailblazers, but I went from a Bontrager XR4 expert 2.35 front and XR3 expert 2.20 rear to these, and I noticed a difference for sure both in size and performance, mainly the ability to claw my up loose over hardpack, and increased roll over. Not sure if the roll over is due to the larger size or the lower pressures though. All I know is, I like 'em, and haven't had any issues cornering with them either.

Anyone know if the Niner WFO would be a good idea? Thinking about buying one just for this, but not sure if this would be a good choice or even work. Other option is Specialized Enduro. Thoughts?
 
I don't have much experience or knowledge about working on bikes, but I'm quickly learning. With that said, in order to do a conversion all I need is: rims, spokes, and tires? I could swap the hubs and other stuff over to the wider rims? Anything I need to look out for? I'm getting anxious and ready to start moving on this and I don't want to make a big $$$ mistake.

That's a very good question. I like some of their bikes, but I'm just not into 29ers. I'd do a chubby 27.5er though.
 
It's been done. Enduro Mag did a test of 27.5x3.0 pre-production Purgatory in an Enduro 29.

Regular Enduro 275? That might be tight, but who knows, those bikes share a lot of parts.
 
Was that a standard Enduro or a 6fattie prototype or something? I have my doubts on a 3" fitting the back of the standard Enduro

Yeah, that Enduro Mag article is the one I referenced. My guess is that it was a stock Enduro 29 since the production 6Fattie is a Stumpjumper and not an Enduro. But that's just my guess.
 
The Enduro 29er have enough space for a 2.8" x 27.50" tyre, maybe a 3". 80mm between stays is ok for a tyre around 72-74mm width.

One guy that sometime ride with me is using a regular Enduro Sworks 29er with the wheels of the Enduro 650B and Ground Control 6fattie tires with no problem. Can change wheels with normal 29er, depending on the trail he want ride. GC 3" with that 29mm internal is 73mm tread width.

 
Frame/fork specific question

I did go do a search first and can't believe the amount of interest generated in the + size tires. And this coming from an early convert to the 650b movement!!

Anyway my direct inquirey is if anyone has tried WTB TB 27.5"+ setup on a non-split pivot Salsa Spearfish? I did see 1 inquirey on one and another for a Horsethief but no actual builds. And what are the chances of a Reba fitting them aswell?

Thanks in advance.
 
JMac,

Check out the and this one.

Unfortunately I haven't found a first generation Spearfish with B+ yet, but its apparent that the Trailblazer/35mm rim combo will fit the rear triangle just fine on a Split Pivot version.

Also check out this facebook group where we've got a good discussion going about the Spearfish: https://www.facebook.com/groups/29plus/?fref=nf
 
My Kona Raijin (19") fits WTB Bridger 3.0's on ASYM i35 rims with the dropouts slid back a bit. My fork (SID XX) on the other hand only has almost no clearance with the 3.0...It looks like I need to scale back to a Trailblazer.
