Hey Everyone!

What I would like to accomplish by this thread is a central place for guys and gals to post what rim and B+ tire options they are running on their standard 29er bikes.

I know there is a lot of pics and posts out there concerning B+ platform compatibility, so lets get it all in one place.

Please include pics of your setup.

I will start off.

I have successfully run the 650b Velocity Blunt 35 rims with TrailBlazer 2.8 tires on my Kona Process 111.





WTB Scraper i45 rim with the TrailBlazer 2.8 tires on my Canfield Yelli Screamy.







This one with a Fox 36



Santa Cruz Heckler set up B+. WTB Breakout 2.5's on WTB Scraper i45 rims





Canfield Brothers Riot will clear 2.8's on i45 rims





Most recently 2016 Canfield Nimble 9 with Schwalbe Nobby Nic 2.8's on Atomik Carbon Chubby 43 rims. These are i36





Please post your setups! If you can include measurements and clearance pictures, it would be even better :)

I am a new Marin bikes dealer. No dual suspension on hand since i am only begining with them. I lurking on dual suspension 27.5+ since almost 2 years. NOW i want it to be a Marin.

Someone know if a Marin Rift zone 29er could handle and 27,5+ rear wheel?

Thanks!
I owned a 2013 and had rubbing with a 2.4 Maxxis Ardent 29 on an original Stan's Flow. Same wheel with a 2.2 Slant Six was fine.

@69tr6r it rides super nice, actually, I like the grip of the Nobby Nics and the added rubber cushion is great for any rocks and roots. Since I was used to a 29'er setup the diameter of the wheel didn't really change, therefore the travel/speed feels quiet similar.

So all in all, I would absolutely do it again.

Olli - very nice RIP9 there. The Nics on your bike look especially nobby and big @ 2.8 too! Going with the same setup on the rear of my bike and decided to stay at 29 on the front to minimize the bb drop. Front will be a 2.35 Mary, so the grip will still be there. ;)

I'm finally done reading the last 20 or so pages here, wow what a lot of info!

I'm looking for a 29er fork with 3-4" travel that will clear the 70mm (actual) wide plus tires-on-rims I already have.

Can anyone suggest a really low-cost fork with straight steerer and QR dropouts that will fit my wheel/tire setup?

I need oil damping as the only real feature, replacing an all-steel fork so not fussy at all.

I've seen popular-priced forks by Suntour, but I know there are others that turn up as closeouts every so often.

Thanks for any help with this, and thanks for all of the useful info posted so far!

Hi guys,
I will finish the interesting 15 page tomorrow, but I have a quick question somebody have converted a canyon nerve 29er?
I'm actually thinking of buyng dt rim but I'm stucked with size, which will suit best for a 2.8 nobbynic 30mm or 40mm internal?
last question; how is wide the nobby nic with this two rim or similar?
Thank you very much, best thread ever

Clearance on the stays is rather good. Just not for muddy trails. All trails in my area close at the first site of rain, so a non issue here. The woman wont ride on muddy trails anyway. I will post up some close up photos of the clearance soon. I'm not sure how much the BB raised. A good estimate would be about 5 to 6mm. judging from the look of my full suspension with 2.3 Nobby Nic's. Tire is rather close to the seat tube. Prior to the build, I had it mocked up with the same Blunt wheel and some WTB Trailblazers. The Trailblazers rubbed the seat tube cable guide slightly. I thought I would have to shave it off. Fortunate for me, the Nic's cleared :)

Hi...anyone is using the XFusion Sweep 650b fork successfully with 650b+ tires?

I have an i35 rim with Rekon 2.8" wheel and is thinking of getting the Sweep fork. Looking at the bulge area of the fork looks kinda tight. Thanks.
I have the sweep, and run fat b nimble 27.5x3.5 tires (severely overstated) on i35 rims. The tires are 2.875" at their widest and see to clear by a good 4-5 mm at the bulges. However the fork arch is very tight, at only about 3mm clearance there. But the FBNs run taller than most.

Anyway, my guess is that it will fit, but I'm not sure by how much.

I didn't have any issues with the crown hitting the tire at max travel / bottom out. The fork arch is the only thing that concerns me. I regularly hear stones pass through it. But the rekon is probably a little shorter than the FBN I'm running.

2016 Kona Procss 153 works with Maxxis Rekon+ front and rear

Ok, the new Maxxis Rekon+ turned up at the shop yesterday and I thought I would try it on a medium Process 153 we had on the floor.

Put them on the stock i29 WTB rims and it came out at 66mm width and after leaving overnight with 40psi in they came out @68mm. FWIW the 2.3 Minion DHF stock were @58-59mm on same rim

So, as I have a large 153 I put the tires on this afternoon :thumbsup: and they fit great. Tubelessed up perfectly. Have moved Marsh Guard above Pike brace to make sure that I have good debris clearance and the rear Marsh is in the same place as with the DHF. In summer I will take off the Marshes.



Photos constrict the appearance of gap, there is a solid fat index finger or more in the rear of the bike, and a little fingers gap below the brace on the Pike and good gap to the sides. In no way will the tire rub even if the casing grows a couple more mm, and there easily enough room for if I tweak a rim mid-ride.

Rode it home after work today and it felt good- will give it a proper go on the weekend, and I am sure that it will enhance the Process' ability even more :cool:
