    New question here. B+ PRIME (or Phantom). Let's talk about it.

    Hi Prime community.
    I was browsing over B+ trend, and of course I started to figure how my Prime would come out with 650b 40mm large rims and 2.8/3.0 airbags.

    Has anybody already attempted or started thinking about it ?

    Oh yes! I am all over this.
    Light-bicycle.com has 38mm (ext) wide carbon rims releasing soon, I am just waiting for that.

    To be honest.... if I don't like it... the wheels will go on something designed for 27.5".

    Talkin' about rims, NEXTIE already sells a 40 mm carbon.

    I don't have another bike, so of I don't like I have to sell.

    Subbed in, interested in B+, but more so for the rigid. but if I get some, of course I'll try it on the Phantom/Prime. But just from my measurements, don't think you'll have any trouble what so ever running them on either the Prime or Phantom. 29+ might even fit, but chainstay length could be an issue, but not width clearance.

    Yeah, chainstays would be longer than a B+ specific frame, but this won't change anything in my ride.
    my concern was about tire clearance, but with measured 8.2 cm between stays, for sure I can use the 2.8 wtb trailblazers given at 7.2 cm section, or maybe some fattyer tires.
    The 727 mm reported diameter of trailblazers will drop the BB 1 cm (at 33.5 cm low setting ), as overall diameter difference between my 29er maxxis 2.3 DHR is -2 cm.

    LB38mm wheels on the way...

    These tires are expensive!
    I wonder if the Vee trax fatty 27.5x3.25 would fit?

    Wow, I missed the boat on this idea! I was eyeing up the Salsa Bucksaw because I like the idea of big tires at low psi, never even thought of 650B with "sort of" fat tires. Was just thinking of replacing my EThirteen rims with something wider and going with 2.5" tires but I like this idea even better. Can't wait to see what the results are!

    Unfortunately I´m out of budget for new parts right now, but would like to try 26"+ semi-fat 2.8 to 3.0 tires on my Spitfire.
    According to a chart of an article on mtb-news.de the 26"+ diameter is almost identical to a 650B 2.3 or 2.4 tire ...

    I mounted up a 29x3.0 Knard / Flow Ex on my Prime; pics are on page 59 of the Prime production thread. Based on that, I'd say B+ could definitely work with the right wheel / tire. Also, we've got adjustable dropouts so the BB height can be raised if needed.

    With generous tire clearance and adjustable dropouts, these bikes are very versatile. When tire manufacturers finally start producing 29x2.7ish tires, I'm looking forward to trying them on my Prime.

    Oh thanks, I missed that. You could run '650b' dropouts to create tire more clearance if you did want to run this setup in mud and slush.

    My question would be: Where there any differences to the current 650B-dropouts? These ones lengthen the stays about 10mm ...

    My other question would be: Is there a market and demand for 29+ tires? I can imagine that 650b (in general) and 26+ and B+ could gain popularity and sales in the near future. Maybe not for the racers among us, but for the all-day-explorers ... ?!?

    The dropouts have not changed, so yeah, the clearance would increase by approximately 10mm.

    1/2 Phat Phantom w/ 29+ tyres

    Curious to all the folks interested in these + tyres for FS as to the why? Maybe I'm missing something, but the Prime/Phantom already have fantastic suspensions, pair that with any of the available "normal" 29er rubber already available up to real 2.5" tyres and you've got an awesome machine, can't see the need or want for so much bigger. Current tyre setup, WW LT rear, 2.35" Ikon front in dry conditions and loving it, combo is very fast, but the 2.35" Ikon really does offer a lot of grip for how fast it is. Have my 2.4" Chunky Monkey for the wet or a more aggressive setup.

    I did a check this AM, and the Phantom will clear a Maxxis Chronicle with the drop outs set to the slackest position, i.e. longest chainstay length, but clearance would only be for absolutely smooth dirt trails with no debri to get caught up in the tyre, at least IMHO. Also the F34 has clearance, but wouldn't trust in on anything more than smooth dirt with no debri to get lodged between the tyre and arch.

    Dear Keith, yes, that´s why I questioned some possible "+" dropouts. Can´t imagine a significant difference versus the current 650B-dropouts, except being longer than 10mm for 4. tires ... ?

    Good question!
    I have no (1/2) fat-tire-experience myself, but from what I´ve read those tires offer more traction/grip and better rolling-resistance. The right air-pressure seems to be the key. Smaller volume-tires should have faster rolling, but these big ones would make for a better all-weather/all-terrain usage ...

    Well honestly my interest in the "+" market is for my rigid Karate Monkey or just rigid in general, but just toolin about on the Phantom with those tyres this AM in my drive, they felt sluggish and overkill to me, didn't inspire me to want to leave them on and go give them a try in dirt. In contrast to on the rigid where they feel fantastic, unfortunately the Monkey won't fit 29+ in the rear, so only on a 2.4" Ardent. Currently the 29+ are on the WTB ST i25s and tyre profile is very round, curious what will happen when I get the Velocity Dually 45mm external amd 39mm internal rims built and them mounted up.

    I was talking about having shorter dropouts for 29er and B+ so to reduce chainstay length. (possible with less wheel diameter)
    may be Rune's or Spitfire's 26er dropouts would shorten chainstay as well, but I don't know how they compare with prime's dropouts

    decrease overall wheel diameter (sweet spot between 27.5 and 29?) without a new frame/fork
    traction at 15psi

    Thanks for the pics. Can you please revise your post to show that these are 29+ tires? Other 27+ threads have already gotten pretty confusing with random 29+ tire references and pictures.

    The parts of this set-up you didn't like could be related to the 29+ wheelsize- certainly the clearance would work with 27+ and the wheel would spin up faster. Part of the allure of 27+ is that it could be nearly a wash with 29, in terms of diameter and weight.

    Lean a fatbike over through a fast corner and you'll have a 'wow' moment. Then imagine it might be possible to capture some of that with wheels that aren't quite as ponderous, in a frame I already have, and as you point out, has great suspension characteristics. That's is why I'm watching this develop with some interest. I'm still recovering from a period of being a single income household and have to pick my battles, but tire selection will likely improve as this ferments a while.

    I get what you are thinking of.
    Well, as far as I know the (short = 26" = 142/150x12) dropouts work for every KS-Link frame, including Rune, Spitfire, Darkside, Prime and Phantom. The (10mm longer) 650B dropouts are mainly for the Rune, Spitfire and Darkside to convert them for the midsize-wheels, but can be used on the Prime and Phantom too, if you like longer CS. I´m not sure if shorter than the 26 dropouts give enough tire-clearance for B+ wheels/tires in the Prime and Phantom rear. Take a closer look to my earlier posted chart. The diameter of a 26+ is almost identical to a 650B while a 650B+ is almost identical to a 29 ...

    Yup, so absolutely get that.

    Reply title revised to state 29+ tyres. Can see your point with the 650B+, somewhere between 650B and 29" normal tyres and running one of the 2.7" would give a bit less of the fat bike feel. Pics just show how much clearance the Phantom has, so if they come out with say a 2.7" 29er tyre it could fit.
    Only place I'd imagine I'd be looking at these for an FS would be in a place where there's lots of sand/silty, lose soil where suspension doesn't help, only big, floaty tyres.

    Never ridden a fatbike, not a chance to demo one down here unless I bring one in, so like FM, this is a cheap and easy thing to try to see what "fat" feels like. Maybe I'll give it a go on the trails, but it just felt heavy and cumbersome to me on the Phantom, but felt perfectly right on the Monkey. Could be having F&R 29+ on the Phantom and feeling the weight to spin up as compared to the weight/spin up of the 2.4" Ardent, although will say the Chronicle didn't feel (in hand) like it weighed much more than the my Ardent, think it's more down to the contact patch being so much bigger.

    Yup, as far as I aware, all the "normal" drop outs swap between all the KS-link frames, just the 650B are different/longer. Liking that idea NS, could be interesting if someone wanted the float of the 29+ tyres on a Prime or Phantom. Going by what I've read a 650B+ tyre will be nearly 29" in diameter, so not sure how much shorter you could honestly make the drop outs/stays to accommodate that small savings.

    If WTB Trailblazers are 727mm in diameter as reported, the
    20+ mm less than my maxxis 2.3 dhr is not really almost the same as 29er! That's room to play with.... like 10mm shorter dropouts.
    I don't have experience to know how 10 mm less in chainstay length would change bike character, I probably wouldn't even feel it.
    It was just about thinking perfect fit for every wheel size.
    big + for banshee

    Yes, the bead to bead measurement is 165mm and it stretched to 168mm after a few weeks at pressure. On a P35 it measured 64mm (shown) and 66mm on a Nextie 40mm. It is rated at 67mm which it would meet or exceed on a Dually or 50mm rim. It never reaches "2.8" which appears to be its name, not its rated size. It's a 2.5 - 2.7 tire depending on rim.

    It's shown next to a Goma 2.4 29er. The Goma is 160mm bead to bead and is 2mm narrower and 2mm shorter on the same rim. There is a 34mm difference in diameter regardless of rim size. This is true for the Trail King 2.4 and WTB Trail Boss 2.4 as well.

    This is not nearly as a 29er diameter, I'm gonna wait beefier tires.

    Dave Turner said the same thing in the King Kahn thread:

    "BB will be 13.3" with 120 Bluto and 4" tire. So, a 29 tire on 622 BSD rim will work! The WTB 27.5x2.75 is notably shorter than even an XC 29r OD at tread so... no."

    There's a lot of misinformation regarding this tire, it is not a "plus" sized tire at all and it comes nowhere close to a 29er in diameter.

    Well, if TBs are definitively not as 29er, on the other side seems that VEETRAX 3,25 B+ are really almost like 29ers...but.... will hardly fit Prime mounted on a 35mm channel rim, as you'll have a mere 1mm side clearance.
    Better would be with narrower rims but you probably end up with side rolling issues.
    Worst thing absolutely won't fit my pike.

    Here's what stated on:
    twentynineinches.com
    Vee Tire Trax Fatty 27.5″ X 3.25″ Tires: Quick Review

    ...Unfortunately I have found my other attempts with different forks to not be as successful. Neither the ROCK SHOX, FOX, or MAGURA fit the Trax Fatty B+ tire......

    ....Initially for this test I used the broad IBIS 741 wheels, the same as I rode for the Trailblazer test. The dimensions for the Trax Fatty on this rim (35 mm inner dimension) revealed that the carcass and tread width are absolutely identical on this tire at 79 mm (@ 1.25 bar tire pressure ). Not quite the advertised 3.25″ (or 82.6 mm) , but on a properly wide rim of 50-60mm, it may well come to the desired dimension. On the slightly narrower AMERICAN CLASSIC Wide Lightning rim the tire comes in at a smaller 76 mm......

    I agree, the difference between 650B and 29er is simply too great for a drop-in to work without compromise. We need to see some B+ options in the 3" range.

    yeah, let's see what new VTF or panaracer 3,0 tires look like.

    Perhaps, but the Prime has a few tricks up it's sleeve that make this more viable than it would be on other bikes. The banshee prime geometry is based off a 546mm fork, basically a 140 fox32 or a 150 pike. But a 160 fork feels great with the slack setting. Now, combine the 160 fork with the drop-outs in the mid or steep setting, and your BB could be 14" with standard 29" tires. So with those settings, losing some wheel diameter would get the BB down to proper height, and the angles would still be pretty much as designed. The tire clearance on the Prime is also perfect for these huge tires.

    So on paper, it looks like it would work perfectly. Has anyone actually ridden this set-up though? Doesn't seem like it.

    I'm not feeling the love for the tread on the WTB tires, for our local conditions. And at $100 a tire... yowch.

    I had actually ordered up some wheels to try this, but I am going to put them on a spitfire instead

    I agree regarding the Trailblazer. It seems "designed" for the kind of riding that doesn't even justify a larger tire IMO, that being lots of light trail and paved surfaces.

    Of course, it's not really larger anyway. At 165mm bead-to-bead, it's only 5mm larger than several 2.4" tires available from WTB and others (Geax and Conti that I know of). Their Breakout is 2.5 as well and is almost certainly the same casing size but 2 ply. Several options basically the same size once you put them on a 50mm rim.

    I've also built a wheel to experiment with but only a rear in my case. I won't have a Prime, though, until February. If + works well at all, I'll be curious whether 29+ or B+ turns out better. Without true 3" B+ tires I think the question is moot.

    As for 29+ I dare say Prime tire clearance, supposing to use Maxxis Chronicles, is going to be on the short side or a no go, unless you change the dropouts with 27,5 model, that up in the thread are reported as swappable on every KS link swingarm. Just keep an eye on side clearance tho.
    Maybe Keith will chime in and confirm.

    You did look at my pics right? The Chronicle/29+ tyre fits in the Phantom with the drop outs in the slack setting, i.e. the longest chainstay length. Phantom and Prime have the same room in there rear tris. Clearance is not huge, but definitely rideable in the dry.

    Sorry, I didn't remember you posted about Chronicles.
    good to know then, sure is a tight fit but really usable in dry conditions, 27,5 dropouts will do the job in muddier times if having enough fork clearance.

    Would you please tell me the maximum diameter of the chronicles at max suggested pressure ? I'm just curious to know if they really fit my RS Pike.

    Best I can give you is on an ST i25 rim @ about 15 PSI and get a smidge over 29 7/8" or 759mm.

    Thanks LyNx,
    wow!!! 15psi (at rear I suppose) it's a really low.
    I thought if I mounted the chronicles I'd have inflated at 20 psi min.
    But as far as I know you are a big guy like me, so if I eventually give 29+ a try, I think I'd love such low psi... and on wider rims you could go even at lower pressure.

    Actually no, there's nothing "big" about me, I am tall, but barely 180lbs geared to ride. This is just on a rim since I don't actually have it mounted up on a wheel right now, trying another. 15 PSI is what I use for the front using a Topeak Jo Blow guage and actually quite high, even for the rear according to most, but this is my first time trying this low pressure game, so taking it easy and conservatively at first.

    Well, I'm 15 lbs more, geared, and in worst case i'd go at max suggested pressure. That's anyway 10 psi less than my actual ride.
    I didn't immediately consider 29+ because I supposed there wasn't enough diameter room on the frame but now I'm discovering that real limit is fork. According to your measuring there's 2-3 mm clearance on the Pike, and you cannot put different dropouts on that.

    I'm curious, did anyone ever measure the width of the rear chainstays at both 14.25" (B+) from the axle and 15" (29+)?

    My rough check gave me 82mm at B+ size.

    Is that both at the chainstay and seatstay? 82mm would be wide enough to fit a 3.25" VTF on a wide rim, and then some!

    after accurate check, side clearance on my prime is 81 mm at both seatstay and chainstay

    For a safe ride in dry conditions I wouldn't go wider than a 75 mm tyre with well dished and trued wheel.

    I think 3.35 VTF is a no go on prime with wide rims, but also is a no go on sub 35mm ID rims for other reasons.

    Hey, even the ability to run the 3" tires is pretty cool, and once you've got the wide rims it won't hurt to try the 3.25" tires. Plus, the VTF only measures 76mm on a 40mm rim, so I think you'd be safe there.

    Now if only Banshee could make the Phantom 1 pound lighter...

    B+ PRIME (or Phantom). Let's talk about it.

    The issue with a 29+ tire in the Phantom is not so much chain stay clearance / width but rather the "bridge" that connects the chain stays behind the seat tube. The 29+ wheel diameter is too big.

    I would think that this wouldn't be an issue with a B+ wheel since diameter is supposed to be close to a normal 29er wheel.

    We haven't tested this, but is an option that might make more options possible.

    If you run the '650b' dropouts on the phantom or prime it will increase radial tire clearance buy about 10mm which may make some 29+ options possible.

    I have a set of the 650B drop outs, just waiting on my 142/Dually45 rear wheel, but should be borrowing a "normal" one this weekend to start testing, but won't be ideal as won't be on the Dually45 that I have for the front. As I reported earlier in the thread, a 29+ like the Chronicle will fit into the Phantom/Prime with the drop outs set in the slackest setting, hence longest chainstay length and you could ride it on dry dirt trails, but definitely no room for anything to get caught up in between the tyre and frame.

    Also along this topic, hoping to soon get a set of 650B Blunt35 wheels and some 650B+ tyres to test on my Phantoms, think it'd be nice, especially on the Mediums when wanting to get them to fit shorter people, just need to get a set or two of 170mm cranks. Will of course also try them on the Phantom.

    Bit of an epiphany for me regarding wide rims - As I said, have a Velocity Dually45 front for 29+ originally for the rigid and then when it fit to test on the Phantom and also on the Paradox. This week just for fun since I was waiting on my rear Dually45 wheel I decided to throw a normal tyre on the front Dually wheel, a 2.25" Smorgasbord, figured it'd be overkill, it was not, well maybe a tad. The support it gave to the tyre and how solid it made it feel was amazing, no tyre roll at all, flattened out the profile a bit (they're a very round tyre on a 125/Flow) and changed it from a tyre I wouldn't run upfront to one I have no problem running upfront. It's also changed my expectations of rim width in relation to tyre width and as such I won't be ordering a rim under 35mm wide for myself in the future - have always felt tyre roll/squirm quite a lot on all of my frames I've had and I think this will stop that problem.

    I did some experimenting tonight. Took the rear wheel off of my Krampus and put it on the Phantom to see how 29+ would work.

    Surprisingly, it clears the seat stay bridge that I thought would be the problem... although it clears by like 1/2 mm or so. The tire bottoms out against the vertical struts at the front of the rear triangle though. Also has maybe a hair's width at best between the tire and the front/sides of the CS yoke.

    Having said all of this, I think that 29+ could work in the Phantom with a narrower rim (I have Nextie 50mm rims on my Krampus) and the 650b dropouts.

    So I ordered a set of the dropouts tonight. I already have 35mm Derby rims on the Phantom and I know they work fine with 29+ rubber. (I used Derby as my original Krampus wheelset before deciding to try the wider rims.) I actually just swapped out new tires on the Krampus recently, so I have a pair of Knards that I can put on the Phantom to try it out. I am running a MRP stage on both Krampus and Phantom, so I know I have the clearance I need on the front end. If all works out, I should be rolling in a week or so. I will post pics and results when I have the new dropouts.

    I'm curious, have you mounted up any of your "normal" tyres on the Nexties? I was absolutely blown away by what mounting a 2.25" Smorgasbord to my Dually45 did, put next to a Chunky Monkey on an i25, they both measured 61mm at the casing. So I thought since I'm waiting on my 142 rear to try the 29+, why not then see what the CM did on the Dually and holy cow, it also grew about 4mm, it's absolutely huge now. Know for sure that I'll be running the Dually wheels on my rigid, but now wondering if not on the Phantom/Prime as well instead of building a set of Blunt35s

    All this wide wheel talk has me thinking. I see 29+ won't fit...which is just fine. But thinking the Dually or Derby would be great to try with the 2.4/2.35 Ardent/Ikon. But I refuse to give up my 36h CK hubs, and don't think Derby does 36h drilling on 29" rims. :frownyface.jpg:

    Maybe I just stick to my tiny FlowEX for a while?

    Derby doesn't stock 36 hole 29er rims but the website says "email for custom order hole count". It's worth a shot to see if he can do it.

    Also sadly for you, the Dually does not come in 36 hole, only 32. Personally I think you should keep a set of "light" narrow wheels and build a new set of "whatever" wide ones with the Derbys or Dually or some such.

    Sorry, is this my credit card company talking? "Go ahead Jon, max the card out Jon, it will be ok"!!

    I cannot afford another wheelset, much less justify having two. If I upgrade, it will be on the bike 24/7/365.

    LMAO Well, for the price of the 2 Derby rims you could afford a full wheelset with the Duallys and decent enough hubs BUt if you're set on just one wheelset, then get in contact with them and ask about getting the 36 hole option.

    Full details here Let's speculate about the new Banshee 29er!

    Drop outs are the 650B ones. A Chronicle fit into my Phantom with normal drop outs in the slackest setting, but barely any clearance for debri, 650B adds 10mm in chanstay length.

    No ride time yet - it is snow/sleet/raining here so it will probably be a few days at best before I get on a trail. No idea if I will like the setup or not. (Although I really like my Krampus.)

    It was a fairly modest investment - I just picked up a set of the 650B dropouts and was good to go.

    Already had the Derby 35mm rims on the Phantom, and I just pulled the Knards off of my Krampus recently since I got different tires for it. For now I will probably just use my Krampus front wheel (as shown) unless I decide to keep the Phantom as 29+ longer term.

    Clearance is good in the front of the tire on the yoke and seat stay bridge. The chain stays are tight around the sidewalls, but still 4-5mm clearance. I actually was able to fit my Krampus rear wheel (50mm rim + Chupacabra tire) in there but it was REALLY tight on the chain stay clearance. Like 1mm or so. As Keith stated in the B+ thread, the 650B dropouts add about 10mm to the chain stay length. I measured before and after and got exactly 10mm difference.
    As stated above no real ride time yet. I ripped around the backyard a little and it seemed ok. Plusher than the Phantom normally feels due to the extra cush in the tires. Bike feels taller (duh) when you throw a leg over it but it didn't seem too different once I started riding around. I am guessing that BB height is somewhere between 0.25 - 0.5" higher (forgot to measure). We will see how it does when I get on real trails with tighter corners.

    The rear felt a little squirmy - I will probably have to add just a touch more pressure. I was at ~12 psi which is what I usually run on the Krampus. This is also partially due to the Knard. If I keep this setup long term I will probably switch to a Chupacabra for the rear tire.

    As AOK said, when I gave it a whirl with just the normal drop outs in the slack position on my i25 wheelset, to me it felt a bit too "squishy", like overkill, toolin around on the drive, but am curious to try it with the 650B drop outs and Dually45 wheels (just waiting on another Dually rim).

    Pics below showing clearance with normal 150mm drop outs in slack position.

    B+ PRIME (or Phantom). Let's talk about it.

    Forgot to mention - the 29+ setup added approx 2 lbs. A little more that I would have expected.

    Very cool AOK!

    The Prime should take a 29x3.0 tire as well with the 650B dropouts.

    The 650B 142 x 12 drop outs come with an axle and hanger, as does the 150 x 12 drop out.

    Dunno. The drops on Jenson are the whole kit with axle, hanger, and mounting hardware.

    Finally managed to sneak in a ride on the Phantom+ between the ice/snow/rain/repeat that we have been having lately.

    I would have to say it is pretty much what I expected.

    The good:
    - The extra cush from the + sized tires gives the illusion of a very plush rear suspension.
    - Traction is amazing.
    - The extra rollover from the larger wheel diameter is awesome
    - Added BB height was not noticeable
    - Bike was surprisingly nimble despite the larger heavier wheels

    The bad:
    - The Knard was definitely rubbing at times on the drive side chainstay.
    - Now that I have ridden other 29+ tires, the Knard seems like a lousy rear tire

    I will have to do some investigation into the tire rub. I took the wheel out when I got home and it wasn't bad enough to leave a mark that I could see (other than just a dirt smudge). So it couldn't have been rubbing that hard - although I could hear it at times during the ride. I will check to see if the wheel is true, etc, but I think the rub is just due to some tire squirm + tight clearance.

    As with my Krampus, bombing downhill on the + setup is great. Loads of traction with even more rollover / momentum due to the larger wheel.

    B+ PRIME (or Phantom). Let's talk about it.

    Following up - my rear wheel was out of true. So that is likely the cause of the rubbing.

    AOK,

    How much do you weigh?

    I got my Innova's yesterday...the sidewalls are thin, how are yours holding up?

    I'm having second thoughts on putting them on my Prime (I weigh 240 lbs). I still have not picked up my 650b dropouts yet.

    How do their sidewalls compare to the other 29+ tires you've tried?

    I might wait for Dirt Wizards to become available and hope they don't cost $120 a piece.

    I'm probably about 200 lbs all geared up.

    I agree that the Innova sidewalls are thin. But I would say they are not any worse than the Knard (120 tpi) sidewalls.

    I haven't had any issues with either Knard or Innova Gravity, although torn sidewalls are not a big problem in general on the trails I usually ride.

    The Chupacabra sidewalls are thicker - you might try them or the Maxxis Chronicle. Much pricier than the Innova Gravity though.

    Impressions from round 2 of my Phantom+ experiment here:
    My new FS 29+ Rig- Mtbr.com

    Liking it much better this time around. I will probably keep the + setup for a while.

    What's the inner width of the rims?
    And what is more important what was pressure? Chronicles are like balloons - just 5psi can add 2 mm each side.

    Any updates on these experiments?

    It would have been sweet if Banshee tweaked the rear swingarm to provide a bit more clearance for the 29+ setup.

    Nothing further with me and trying this. Would have to ask why would Banshee tweak the design for 29+ when 650B+ can already work just fine with just about a 1/4-3/8" drop in BB height? IMHO 650B+ is a better solution keeping wheel/tyre weight about the same as current 29er tyre/wheel combos with the same sort of tread and casing and the slightly lesser size means spinning up the wheels won't take any more effort. FYI, if you want that little extra clearance, just purchase the 650B drop outs, gives you an additional 10mm in chainstay length, which is basically all you need.

    Been riding Dirt Wizard 29+ on my Prime with the 650b dropouts, really like these larger tires, wish they would fit on my other long travel 29ers.

    I might try to pick up a used phantom and run 29+ on it too.

    So far, I'm not interested in running any other 29+ tire (like the Dirt Wizards tread).

    So far, I've ridden them on my usual trails but also at the Bike park (no big jumps or big drops; I've only ridden the DW+ at the Bike park).

    I have two sets of wide carbon rims (941's and Roval Fatties)...the 941's with DHF 2.5's mounted and the Fatties with DW 29+...I will eventually be riding them back to back, I expect to like the DW 29+ more.

    I'm not sure how low of pressure I can run (I weigh about 250 suited up), so I will eventually use Procore to help protect my rims from rock strikes regardless of which tire I run.

    No updates from me. For now I am back to normal 29" tires. The 29+ thing is loads of fun, but I am not sure if I want to keep the Phantom like that all the time. Luckily with the modular dropouts it is a quick swap to go from normal to plus mode.

    no news from me. I'm having home restoration right now so I'm just broke.
    But as soon as funds will stop flowing out my bank account i'll buy carbon B+ rims and tyres and build new wheels.
    I'm sure such configured Prime will be a joy machine!!!

    It seems that all the thread is on 29+ experiments, did someone actually explore the B+ route?

    What was the max width between the stays? It'd be rad if a VTF 3.25 or something even bigger (27.5 format) could fit.

    Shame that even with the 650b dropouts on the Prime/Phantom that neither will fit the bigger 3.0 tires like the Bombolini, but I don't forsee 29+ getting much bigger than that.

    I'm in the process of doing that - Finally just got my WTB Trailblazer 2.8" tyre for fitment and to just see what it's al about. On a Flow rim at 40 PSI it measures 64mm on the casing, 61-62mm at riding pressures, imagine that on the proper rim it will be a bit bigger, plan is for WTB i35 wheels. Now that there's a few more options available in 650B+ I'll be looking at maybe another as a front tyre option.

    Clearance in my stays is 80-81mm on both Prime and Phantom, so lots of room. Who told you the bigger tyres won't fit using 650B drop outs?

    I thought someone had tested one of the larger 29+ tires on wide rims and it didn't fit the bridge, even with 650b drops. DW or Chupa on Jungle Fox rims?

    Could be wrong. Would love to be wrong.

    It'd be rad if Banshee made the Paradox with swap drops, made the stock 29er drops the "short/26" style, then allowed the 650b drop to fit 29+. On the website they display a Paradox with Maxxis B+ tires.

    I fit my Prime with 29+ tires on 35mm external/30 mm internal rims light bicycle rims. I tried a Chronicle in the rear, which rubbed under suspension compression, and a Dirt Wizard that fits with no problems. However, I currently switched the rear to a Minion DHF 2.5 for something with a burlier casing.

    I had a 3.0 Knard / Jungle Fox on my Phantom. Bridge clearance was fine, but it was really tight on the sides (chain stays). I had some chainstay rub which turned out to be due to the wheel being out of true. Once I fixed my wheel the rub issue was gone, although clearance was still tight.

    With a Derby 35mm rim there was plenty of clearance. I suspect a 40 mm rim would also work well. (The jungle fox rims are 50mm for reference.)

    Honestly after playing around with 29+ I think I was happier with the Derby 35mm rims. The Jungle Fox setup had a nice solid footprint but seemed a little slower overall. With the narrower rims I was able to go *almost* as low pressure-wise and the overall ride felt faster / more playful. Just my two cents.

    One place that the JF rims excelled was when I was running Knards. For whatever reason the Knards just felt squirmy on my Derby rims. When I swapped them for Chupacabra / Innova Vidar tires the Derbys did a lot better.

    ^AOK I can honestly say I am a little dissapointed with your follow up on the 29+ options with the prime/phantom. I was hoping for pics and full writeups regarding performance and impression.

    My dream wheelset consists of 35mm derby wheels /w maybe a maxxis chronicle or dirt wizard. Don't make me force info from you...it won't be pretty.

    Keep returning to this thread hoping that somehow clearances have magically expanded since my last visit.

    Have two 29+ bikes now and really can't see ever dropping in size, the format really suits me. So the full suss question pops up all the time and not having the money at the moment to go down the Lenz route or custom, I end back here.

    Have the opportunity to grab a mint Phantom second hand and would be grateful if anyone has an opinion on wether a Jungle Fox / Dirt Wizard combo would fit? Reading between the lines it appears it may just but would love to hear what you all think.

    I'm running 29+ Dirt Wizards on my Prime...

    You have to purchase the 650b dropouts to get enough clearance in the rear...those dropouts move the rear axle back about 10 mm on the Prime/Phantom.

    Thanks, I am aware that is the way to go and would be purchasing the dropouts. It is the Junglefox being in the mix that worries me. I have been told Chupacabras on Junglefox will not be an option width wise, but the Dirt Wizards are much skinnier on the Carcass width so was hoping they would fit?

    I'm running 35 mm Fatties (I do have 941's...but with 2.5 DHFs mounted)...doesn't seem like that wide of a rim would clear...will post a pick later of my current clearance if you want to see it...not sure if the phantom width is the same.

    That would be great if you have the time, would love to see, but it looks like you've answered my question, 50mm rims will be too much even with the skinnier tyres then. Shame, love the Junglefox and would not want to go smaller. Might start saving those pennies for a Lenz.

    I can post a pic of a Dually45 with 2.4" Ardent or Chunky Monkey, unfortunately don't have the end caps for 142x12 or I could post them with Chronicle or BFT. Will look at an accurate way to maybe do that with the 135mm ends. You could also go the 650B+ route to get the same high volume, big contact patch thing going without needing to run the 65-B drop outs.

    Didn't notice that much difference running 2.5 on 35 mm Fatties vs 41 mm (941's have more spokes and feel a bit stiffer...but I am not hard on wheels), never been on anything wider.
