Paging Dusty!

Great idea! I think we need a B+ Canfield thread in general since all the 29 inch frames are B+ compatible up to 2.8 it seems.

 

Does anyone need more than the 2.8?

 

Without a doubt, a 3" compatible N9/Yelli/Epo would be my next bike.

Full squish? Probably not.

 

I can see some benefits to a 3.0 ..even full squish
But, only for a clean sheet new bike design. Plus tires are not for everyone and, 3.0 B+ would probably narrow the available market significantly with the geometry and design compromises. It's much easier to get both a B+ 2.8 tire and a 29'er 2.5 tire to work in the same frame..


I edited the thread title.. any suggestions for a better one?
I'm looking to maybe add a Riot to the stable and need clearance info on the Riot a.s.a.p..

 

I ran 2.8 nobby nic 8 the rear with 30mm inner roval wheels off my enduro. It worked, however was super close on the drive side chain stay. So much that if I hit any mud it would cause issues. I DID very much like the feeling of that riot geo with plus size tires on it with the bottom bracket lower it felt better. So much so I am thibking about testing out a big volume 27.5 set up on the riot but not quite plus sized like a 2.5 minion wt or a set of wtb breakouts.

I've had the DHF 2.5 WT mounted up on Derby rims which have a 35mm inside width.
the profile of the tire is better then the 2.3 DHF on the same rim. I can tell there is more volume to the tire and can run it at a slightly lower pressure. There was more then adequate clearance on my 27.5 Endorphin. The Nobby Nic 2.8 is a whole different animal. much more volume. unfortunately it would lightly rub on the Knolly with a Derby rim. I just mounted up a B+ 2.8 Chupacabra to try. It might be the limit of tire size for that frame. I know it's not going to work everywhere. But, I'm hoping for the best on at least some of the stuff around Arizona

 

Just finished wheels for the N9 B+ project. Hope Pro 4 to Asym i35 (hat tip to EatsDirt for the help!) with 2.8 Nobby Nics. TrailStar front, PaceStar rear. First ride tomorrow!

 

Nice:thumbsup:
any issues with the build ?

 

That nimble 9 looks good!

Very nice, Kragu! That's pretty dang close to what I wanted to do, but I ended up buying a Yelli that popped up on craigslist. I'm still gonna build some Blunt/Hope wheels for it eventually.

What's it weigh?

 

Thanks! I haven't weighed it yet, but I'm guessing about 3/4 of a pound more than my 29er version which came in just above 27. That was with i9 Enduro wheels and a non-exo Ikon/Exo Ardent combo. These tires are surprisingly light- the PaceStar came in at 874g and TrailStar at 889g.

I'd guess I'm still under 28, which isn't horrible with a dropper and a 2100g wheel set.

What length did you end up ordering and what ERD did you use for the i35s? Mine came together good using a 563 ERD and 272mm spokes with the older Pro2 EVO hubs.

I used 563 and a 271/272 combo on each wheel. What's the flange diameter on the Pro2? 57mm on the Pro4.

 

Got in a decent 18 mile, 3200 ft ride today, the first on the B+ wheels. A little bit of everything - a ~40 minute fire road climb I've done about 10x, another 30 minutes of exploring a mix of ST and FR, a fun flowy single track descent, and a short, steeper, mixed conditions tech descent.

I crushed my PR on the long climb by almost 8 minutes. I'm fitter than I was and on a more suitable bike (a 6" rear 29er) than on my previous PR, but 8 minutes is a lot. Fire road was steep at points, loose, sometimes sandy and often rutted. I can think of a bunch of spots where both the float and grip of the plus setup was really nice. Would I have been faster overall on my Ardent/Ikon setup? Probably, but I'd guess not by much. That setup is about 400g lighter than this one, so despite some advantages the plus wheels give, I suspect over 38 minutes, lighter wheels might win out.

The ST descent was really damn fun. Half shaded hardpack, half sunny and steeper loose over hard, grip was on another level. The extra squish in the rear was just the right amount, and that plus float feeling mixed with great grip was a really cool feeling. I tried to get the squirmy feel people talk about, but I was able to break the rear loose before I felt any squirm. I'd drop a few PSI, but probably just as an experiment - dare I say I found a really nice spot on my first ride out. I'd rather drift than deal with squirm.

By the time I got to the tech descent, I had a pretty good feel for what the bike was going to do in the critical spots - mid speed run outs in silty, sandy, or marbly sections where braking and traction is a priority to get set up for the next section. Riding a HT in sections that might be better suited to a FS, you'd expect the front to kick and crab and the rear to buck, but the extra volume and (again) grip make for a much calmer experience. Obviously, this leads to more confidence, more speed. Not quite FS speed, but better than a normal 29" setup.

I'm tempted to run the same ride tomorrow with my 29" wheels, but I'll probably take the B+ out to another familiar trail.

Bikes are fun.

Nice report! I don't think I need to read any more about it, B+ for me!

I think I'm gonna go with a Hope trials hub, I live in the flats so SS is where it's at (which is why I wanted a N9). I'll need to do some more i35 vs P-35 reading before I choose, then I'll need to pick tires. With the Al frame and SS I might end up in the 25-26lb range.

 

Right tool for the job, that's the key and a B+ HT on a smoooth fire/gravel road climb is going to be fast. Had the same experience on a climb I know well, when I was very fit back in '07 a 5 min 30 sec time was smoking on my 32lb FS, couple weeks back on the B+ Paradox decided to give a bit of a push to see what I could do, well 5 min 40 secs is what I did an no where near the fitness I had back then.

Float and that extra little cush is what makes B+ so sweet, that and the fact that most, like us can most likely fit a 2.8" into the rear of our existing 29ers, giving us basically another version of that current bike, maybe even breathing new life into a bike we maybe thought needed upgrading.

Not sure how low you went with pressures, but with my setup and weighing about 180lbs geared to ride, I've settled on 16 PSI rear and 13 PSI front and I'm very sensitive to squirm. Mine are the Light/Fast casing.

 

I was pretty high on the climbs... Probably 20f/22r. Let a bit out for the descents and when I checked it at home, it was 15f/17r. From what I understand, the NN sidewalls are pretty beefy compared to the WTB. Maybe I have room to move down, but it felt pretty damn good where it was. Any more grip and I'd have trouble breaking it loose (really just getting around to learning to ride that way).

 

What's the BB Height on some of these builds with the 2.8 inch NN? Getting any pedal strikes?

 

Drops BB about 1/2". No pedal strikes for me (one ride), running 175mm cranks.

 

How did I miss this thread?

Expect many sweet pics to follow

I have been rocking the Nimble 9 B+, but am about to swipe the wheels and throw them on my Riot

Here is how she is set up right now.

Atomik Carbon i36 rims with Nobby Nic 2.8's. I seriously wouldn't want anything wider. Thats what my fatbike is for!!

 

Here is a pic of mine with nobby nics.
BB height was a touch above 13.25 No issues with pedal strikes. But I did come off a 5" bike with a 13.0" bottom bracket so I might just be used to pedal timing and ratcheting.

My plus bikes, a Riot and a EPO.

 

Lance,

Which has more clearance for +? Riot, EPO or N9?

Thanks!

 

EPO Does, The Riot is 75, N9 is 73 and the EPO is 78.

 

Uh oh Dusty! You know what that means

Haha. You did, you did. Dusty and I have been discussing a set for awhile now.

How would you compare the plus Paradox to the Phantom in terms of smoothing out the roots and small stuff?

What about the Yelli?
How dare you forget about him!

Here are a few I have of my Riot with 3 different B+ setups.

And not to forget about the Yelli, I attached some of him too

 

awesome!
How's the Pike for those + sizes? More than enough room?

 

Ya, more than enough

Guys, did somebody have good/bad experience running WTB Scraper i45 on Riot?
My order for Kore Realm P35 was cancelled by UC:madmax: and WTB Asym 35 are out of stock everywhere:madman:

 

I haven't done much searching, but it looks like these may be available:

Easton ARC grows up with ARC+ 35, 40, and 45mm wide 27.5+ and 29+ rims - Bikerumor

Easton Arc+ 35 27.5" Rim from BikeBling.com

 

pity, there aren't much options for a 27.5+ non-china rims that are 36h. all i've seen are just 32h.

(don't want to get rid of my 36h hopes)

 

Post up your Yelli Screamy that you converted to the B+. I got a little rub issue in the rear hoping the solid rear axel from Dustyduke22 helps with that or might have to cut some nobbies.

2014 Canfield Yelli Screamy
2012 Fox 34 float 29er 140mm fork
Onyx prototype mtb hubs 11-36 in rear going to 11-42

780mm bars and 50mm stem they are take offs on another bike

I love this set up runs over anything still pretty fast and fun to ride.

Is there a good pressure gauge you all recommend for the plus tires? I was reading about gauge inconsistencies, and that some are better suited for low pressure over others. Any advice out there? I've got the NN 2.8's. Thanks!
