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 :)

My local shop built up a pair of WTB Scrapers with the trailboss 3.0 tires.....I rode down there today and they fit my Salsa EM SS....it is the older model with a straight seattube...actually the first dedicated SS EM....my dropouts were pretty far back and it looked as if I would have a little better clearance with them further forward as the tire would be where the chainstays are indeneted.

Any sub $1000 29er bikes that are B+ compatible? I'm seeing good deals on lower end bikes as manufactures move inventory at the end of the summer.

I know the access xcl 29er is B+ compatible, but I wonder about others.

Jenson has some good deals right now

Sorry all...I rode down there in the afternoon after a long hard ride in the AM to give the shop a few parts for my new Ti EM build.

One of the employees had his SS with 27+ wheels there and offered to let me try them on for size. After 15 miles on pavement in 100 degree heat on my SS I never even thought to take pictures....

FWIW I was pleased with the clearance and will be building a set for the steel EM in time (after the Ti is done and my wallet recovers) and will take lots of pictures then.

Had seen several posts asking this question....and somewhere here there is a picture or two of a blue EM with 27+ wheels...at any rate I thought I would help out by confirming the fitment....of course YMMV.

I have one ride on my Mason 29er B+. I was impressed to say the least with the traction. I need to play with tire pressures, I think I was running around 20 psi. I'm around 210 geared up.
I crushed a personal record over a steep sandy climb and descent. That was an eye opener. I'm looking forward to see what this setup is capable of!
I'm running Arc30 rims with Ground Control 3.0 tires. Clearance was tight, but no tire rub!

Well done sir. You'll absolutely love the way the Mason rides with the B+ tires! My WTB TB 2.8 on a Blunt35 (30mm internal) cleared the rear chainstays on a Mason pretty well.

How's the front clearance on the Pike? Looks a little tight when you zoom in on the pic?

I've got a set of WTB i35's and 15/142 hubs (plus a full build kit). Want to run 2.8 Nobby Nic's... Just looking for a frame/fork combo.

@CougarSlayer Sure, I'll take a caliper measurement and get back to you. Thanks!

I was taking a gamble on the back tire fitting. I wasn't sure if I needed a 2.8 instead. No rubs after the first ride. I was trying to push it too, seeing how the tires performed.

Koo thanks! I am rigging up my canfield N9 in b+ right now with 39mm Duallys and the 3.0 Bridgers I bought are not looking good for the chainstays .. crossing my fingers they will fit the Mrp stage fork! So maybe the specy tires are an option

A friend of mine just got some Arc 30 / Hope / DT Comp wheels 2 weeks ago. They look really good and they have been very happy with them. Weight was 1995 grams if I recall correctly. They were 29” rims but you can do the math to get a ballpark weight on a 27.5” set. I know it’s not a 27.5+ wheelset but it may be of use for anyone looking for a decent wheelset in the $500 price range. And yes, as PHeller pointed out, the Arc rims are 30, 27, and 24 internal.

My Pike 29 and Mason 29er frame are a very tight fit for the 3.0 ground control fattie tires on a 30mm inner width rim. I was a little concerned about buzzing but nothing happened at 20psi. I'll post a width measurement. I can even take some clearance pics to post.
I would probably be more comfortable looking at a 2.8 fit in there, but I had easy access to the fatties so I grabbed them. Running this close a fit might only work in a hardtail frame with minimal flex.

The Specialized Ground Control 27.5x3.0 tires on 30mm internal width rims are 2.91" at the widest knobs. No tire buzz at 20psi, I'll have to see how they perform at a lower pressure.

Below are some pics on how tight the fit is on the Mason and Pike 29 fork.
