For you 29er frame/650b+ converts, I thank you. This has opened up possibilities I hadn't considered. That said, I have a question. If you had neither a 29er frame or 650b+ specific frame, but wanted plus size, would you do it all over again with your 29er conversion or go straight to a 650+ complete bike?
I'm very interested in the Canfield Yelli with Scrapers that have been successfully marriaged. That said, I've been demoing a Norco Torrent 7.1 650b+ specific which is a really fun bike. I like the Canfield frame more (ano alloy, color choices, cool/under-the-radar brand), but have never ridden one. I also get to build the YS whereas I'm stuck with stock Norco while okay, not everything I would put on a bike. For the sake of argument, let's say both bike ride great and are more or less going to cost the same.
Again, starting from scratch, 29er conversion or 650+ specific frame?

 

If you are starting from scratch, it makes no sense to me to start with a 29er frame. You are automatically limiting yourself as to what will fit. Most 29er frames are limited to 2.8 tires, and some will take a small 3.0. And you will be lowering the BB height. Get a proper 27+ frame to start, and then you can always mount a 29er wheelset if you want.

 

Thanks I'll look into that..

 

Looks like that SIR9 is setup 79er+. 29+ on the front and a 27.5+ on the back. The front wheel is dually and the rear is a blunt 35.

It looks kinda cool setup that way

 

Hi guys, what is the widest rim and tire combination dat can fit a non-boost 29er 140mm Pike?

My current fork is out, am deciding whether to buy a normal or a boost 150mm 29er Pike and also convert my front 29er wheel to a 27.5+ while at it.

If I get a boost fork, will have to get a new hub or get a normal fork and use back my CK hub.

For the 27.5+ option I am thinking of using a 40mm ID width rim like the DT Swiss XM 551 and paired to a Nobby Nic 3.0 or the future Maxxis Rekon 2.8...

Pls advice with pics if possible. Thnk you.

Hi I run scraper with on my pike 160 dual position 29 and pike 140 29 non boost forks
widest you can go is 2.8. I run nobby nics 2.8s the measure 70mm when you first put on then stretch to 72mm. I would recommend getting the boost fork its worth buying for future.
But instead of pike have you consider thr yari its only $530 stiffer than pike too.

 

Thanks Kona/ MrHyde,

Think I will go the Boost option then, only thing is when there's possibilit it also usuall means more money spend changing and experimenting. If less option, you will most probably just do with what you have.

Now will decide on what rims/ tires to get...

Cheers.

 

2015 Kona Raijin Works pretty well. The Trailblazer fits with room to spare and the SID will take a 2.8 Vee Trax Fatty with a bit of room. We will see if it contacts the fork under hard effort or not. I tried an 3.0 Trailboss on the rear end but it had some rub on the chainstays.

 

Rim width is important to know here

Niner Rip 9 Carbon

Niner Rip 9 Carbon. Front tire - WTB Bridger 3.0. Rear tire - WTB Trailblazer 2.8. The pictures show a temporary set up on i25 rims while I am building i35 rims. Tons of room at the rear. A little bit tight at the fork (Fox 34). May be really tight on i35 rim.

The bike is ton of fun. The BB dropped to a perfect 13.5". Niners tend to be really tall as 29ers. The BB with 29X2.4 WTB Trail Boss tires was well over 14". The HTA is around 69 - rough measurements. Between slacker HTA, lower BB and gripper tires a different bike.

 

I have Dusty currently building up a wheel set for me. WTB Scrapers laced to I9s. Going to go with the Schwalbe 2.8 Nobby Nicks for now to see how I like them. Would really love to try the Maxxis Rkons but want to be riding these wheels before those come out. I will post pictures of how they fit in the two bikes I am going to try them on. My 2014 Turner Sultan with older dual position RS Revelation fork and my Quiring hardtail with older dual air RS Reba fork. As well as ride reports for both.

Thank you all for the inspiration as well as the great information!

Scott

 

Nice. I've been talking to Dusty as well for a possible WTB Asym i35/Hope Pro 4 "budget" build (March wedding is affecting my cash flow!), and thinking about the 2.8 Nobby Nics. Otherwise maybe try the WTB Breakout 2.5. For a mk1 Yelli frame.

As for that RS Revelation: I have a 2013 Dual Position 140mm with 20mm axle. I'll be interested in hearing how your set up fits into this fork.

 

I've read through this thread, can't recall if it's been mentioned (and I'm guessing there is some crossover in members?)...but singletrackworld has a similar thread with some good info on the B+ compatibility:

650b+ (and other plus sizes if you like) - rim, tyre, frame, fork combinations, « Singletrack Forum

Is this a forum faux pas?

 

A 2.8 Nic on i35 rubs a Mk 1 Yelli. Trailblazer clears OK and is a fine ride.

 

Thanks ghetto. I do think I remember seeing that somewhere along the line on here. I'll read through again before I buy anything. I still need to take the calipers to my frame to be sure of the width limits.

 

Here's my Yelli, set up as above. I'm in Surrey if you want to come and see or try. I like it.

Ha that's UK right? Maybe next time I'm across the pond. For now I'm going on blind faith and trusting what seems to be a consensus that the YS in B+ mode is worth it.

 

Yes UK, I had the feeling you were a Brit somehow.

Trailblazer on i35 works fine. I'm glad I did it. I run a 2.8 Nic on the front, on a 29er Pike.

 

I'm running a Remedy 9 29 with WTB TB2.8s front and back, works fine. Dually rim up front, Blunt 35 on rear (did not have enough clearance for UK mud with a Dually at the rear.

 

I've got an idea for a project where I want to use a spare set of wheels I have for my fatbike that are 27.5 x 55mm with 3.0" bulldozers on them. I am wondering if there are any 29er bikes out there that can take that width of 76.5mm (after I switch the hubs of course)?
I measured some Norco bikes last year but I'll be damned if I can remember the exact clearances but I think it was pretty wide.

 

Add Diamondback Sortie 29 to the list. 2.8" WTB Trailblazer

 

What year sortie and what kind of clearance are you getting? pics? Thanks!

 

76mm is pretty wide for most 29ers. Carver Gnarvester might be your best bet?

 

Niner ROS 9

I know its been well documented that the ROS 9 works with Trailblazers so this is more about showing off my rig than new info. I will say that I am adding a Bridger 3.0 to the front end and should have plenty of room using a Fox F29. I am absolutely sure it would clear in the back as well. All non-boost setup, this thing just has lots of space. What I love is that it doesn't feel like a 29er. I had a SIR 9 that always just felt big to me, the ROS 9 (in the same medium size) feels perfect with the B+ setup. FWIW, I'm about 5-9" with 31" inseam. Anyway, here's some pics from today's roll...(kinda xc setup for these parts)

 

I am selling that Trailblazer if anyone needs one. Its got just a couple of rides on it so basically like new. $42 + $8 shipping obo. Just thought I'd throw it out there since so many in this thread need the smaller tire to make clearance.

 

Hey Nama, can you measure the Bridger knob to knob? Also, what is the inside width of your wheel? Thanks in advance.

 

sorry that I am just seeing this. The Bridger is at 2.87" (no caliper used so there is some fudge factor involved). I've got it rather inflated at about 20psi right now so also bear that in mind. Its mounted on a Blunt 35 which is 30.2 ID. Hope that helps.

 

2016 Canfield Brothers Nimble 9

Here is my newest creation. Canfield Brothers Nimble 9. Tires are Schwalbe Nobby Nic 2.8's mounted on Atomik Carbon Chubby 43 (i36). Couldn't be happier with the build and how it turned out.

Is that a regular Pike or a Boost?

 

Just took the maiden voyage on my new On-One Parkwood B+ build last night. Initially, I have very mixed emotions about it.

This is my first bike with a headtube this slack. Coupled to a 130mm travel x-fusion sweep, the ability to soak up bumps on rutty, rockey, rooty areas was incredible. I found myself steering towards the bumpier line for the first time ever.

And while straight line traction was reasonably good, I found the tires were prone to washing out easily, betraying the false indication of traction put forth by the amount of dirt and rocks these tires fling up. I had to really slow down to have any confidence around a turn. I'm running panaracer FBN 27.5x3.5 on WTB asym i35 rims, tubeless. The tires measure 2.875: at both the knobs and the casing, running 20 psi rear and 18 psi front.

Does my pressure seem too high for these tires? Considering a 240 pound ride weight, I wanted to err on the high side. The tires already felt pretty sluggish, and at some points even squirmy, so I'm a bit scared to drop it much lower.

Anyway, I'm hoping I can dial in the tires for a bit more traction and confidence. If I can, this bike will be a real winner. I already had a PR on one segment I must have been through 75 times in the last two years, so the bike has promise.

I plan on increasing the fork travel to 140 mm, to slacken it out a bit further, and to help with bottom bracket height, which judging by some pedal strikes, sits a bit low. I'll also lose the wellgo MG1s in favor of some lower profile VP pedals to help with the same. The tire clearance is tight at about 3 to 4 mm to the fork arch, and 4 or 5 mm at the rear chainstays. Its only been one ride, but I see no evidence of tire rubbing, nor did I hear any rocks pass through the fork arch. Hopefully none ever try to.

All in all, I really like the comfort factor of the 27.5+, and with a little tweaking, this thing can be a monster on the trails.

Hi Guits. TP here from CLIMB. I too have felt a little sidewall squirm. I'm running Velocity Blunt 35's with WTB trailblazers on a Ritchey P-29er. Generally speaking the wider the rim, the more the sidewall is supported. I'm thinking of building up a set of WTB scraper rims or even Stan Hugo's and trying those. Once you dial in the tire pressure (I run 18 psi front and rear) it truly is a magic carpet feeling. I can feel the tires soaking up the roots on the rear. It's awesome. Since it's tubeless I am not worried about a snake bite.

 

No one's tried on an Anthem yet? Read the whole thread and nothing. Anyone heard of anything?

very nice!!:thumbsup: psi settings and the adjustments you've made from regular rim/tire combo please.
Do you feel the 30id is sufficient for the NN??

 

I'm 240lbs and I was running 17psi in my 27.5 x 3.0" tyres and I reckon I could've gone lower. I put the 26 x 4.0" wheels back on the bike now so now I run 9-10psi. Much smoother

 

Plenty of clearance

I got plenty of clearance for 27.5 x 3.0" Vee Bulldozers on the fatbike frame!

here's a couple quick shots of the Bridger in the Fox F29. Clears no sweat but adds great volume.
