SpecialED Stumpy

I built some wheels for my wife's uncle and he sent me these pics of the WTB i45 Scraper rims and WTB TB tires on his Specialized Stumpjumper. I am not sure what year it is, but is a few years old.

He said it fits like a charm with lots of clearance. I know the rear chainstays are at least 80mm wide at the tire diameter.

Nothing like a 5 inch travel B+ rig...

Just checked the chain/seat stays on a 2013 Stumpy Expert carbon 29er.. measured about 82mm where a B+ 2.8" casing would fall out. Also measured a Pike fork and it's in the 80-81mm range. Your post pushed me over the edge to order some carbon 45mm B+ hoops to build that same rig!
 
This was the reassurance i was looking for. I already have a specialized enduro comp 29er and I pulled the trigger on some Maxxis chronicle 3.0 tyres and got my hands on a set of standard roval rims of a 27.5 enduro comp (my mate upgraded his wheelset for the roval carbon fatties) which have a 29mm internal diameter so i was hoping, praying, that it would work. Judging by everything i read here i am in business! 160mm 27.5+ dually! Giggity! Tyres should arrive on Saturday so i will get to test fitting and post some pics. Wont be able to do a ride report until my broken ribs heal though.
Also, the Specialezed Enduro 29er is also B+ friendly.

Here is a good write up by Enduro Magazine. They even have a pretty large B+ tire on there too :)

I can't seem to find anything on doing a b+ conversion for a Kona Unit. I have a 2012 frame and XFusion Slide fork. Anyone have a link or first hand experience?
I've got no insight on the Kona, but post 72 in this thread shows my XFusion Slide fork with Panaracer FBNs mounted on Blunt 35 rims. They pretty much maxed out the clearance, but I never had tire rub issues (anything smaller than that should be fine)...I've since switched to a DT Swiss fork which has more room.

Santa Cruz Heckler with WTB Trail Blazers. Lots of clearance and the BB isn't stupid low. :thumbsup::thumbsup:
I.. what? wait... what?? 2.8 on 650B in a heckler?
That '06 heckler in my basement just got REAL interesting... I know, it's not the same as the noodle-tube you show, but still..
