    650b on a Chilcotin - with Pics!

    Pacenti TL28 w/ 2.1 Neo-Moto....plenty of clearance!

    Seat Stays


    Chain Stays


    Rear End


    Granted the Neo-Moto is pretty small for AM/Light FR but there looks to be enough clearance to go a little bigger. More testing to come....

    Well besides just putting a tire on doesnt mean it works lol , did you actually take it out for a spin ? and what air pressure were you running in the tires ? Looks a bit too tight :/

    Why would you want to frankenbike such a great frame? I'm sure Noel just got a migraine and he is wondering WTF?

    Sorry, no rides to report...this was just a test fit on an unbuilt frame (I test fit the wheels into just about any frame that come through). Tires have 32 PSI, mounted to the 28mm wide rim. Not sure what kind of 650 clearance you are used too but this is more than a lot of frames offer. It may be a moot point because I am not sure a bigger tire will even fit but I think the possibilities are very cool.

    ....nothing frankenbike about 650b either....wave of the future my friends.....wave of the future. Assuming a bigger tire could squeeze in there I love the concept of a 6.3" travel enduro Chili with the rolling advantage of 650b's. It may be a moot point because I don't think I could fit a quasi-moto in there....but might be fun to play with nonetheless.

    I've had a V2 Titus Rockstar demo for a several weeks now so I am aware of the advantages of bigger wheels and the pitfalls. 650B may be the future but it will be on a frame that is designed around the wheel size.

    Not sure I can find any advantages in a steep angled cross country 29er with gargantuan 18" chain stays like the Titus Rockstar....it is pretty much everything I find wrong with 29er's. Herein lies the beauty of 650b: we can keep our slack angles, long travel, and super short stays while still getting increased rollover. If I could squeeze one into my Endorphin I would swap it out in a heartbeat....although thinking about it I am not sure I would have the heart to....the bike is just so damn good the way it is....only bike I have every built that I have not made any changes to since build up.

    you can't try to derail the 650b freight train people will get their shorts in a knot. . still trying to figure who's begging for 650b, but somebody obviously is.

    Just to be clear...I am not saying running 650b on a Chilcotin is a good or bad idea...just showing those that are interested that the Chili can squeeze a 650b in the back which makes me curious about what could be done with that. That is all. Just saying it fits.

    Yeah I can't see what the purpose of putting 650b tires on a Chili, or any knolly for that matter. They were designed around 26" wheels, so ride them accordingly.

    Seriously though, that clearance looks a little too close for comfort.

    regardless, the chili is a great 26" bike. i would want to try a dedicated 650b bike before i tried to bastardize a 26' model. maybe knolly has a 650b in the works, for me i'm more than happy on 26" and enjoy having tons of choice in rims, tires and forks.

    once 650b has that stuff all lined up, maybe

    me too, i just feel it's kinda crazy to throw 650b wheels on a bike designed for 26". ride whatever you like, but once you start messing with a bikes original design, it's acrap shoot

    Well, this proves to me that most XCish 650b tires won't be significantly larger than a nice high volume 26er trail tire. My moderatly worn Advantage 2.4 on the rear has less than 3/8 inch clearance. As new I'm guessing it was maybe 1/8 of an inch smaller than that tire. I'll take good traction and a sturdier tire on this one. I'd still be curious about a 650b trailbike that was designed to fit something like a 2.4 Trail King.

    wow....Craigstr negative repped me for this thread. Really man? Not really sure what to make of that. At least I got my first negative rep....my cherry is popped!

    For those that are interested, a Nevegal 650b rubbed....so it looks like any substantial 650b tire is not going to work.

    Oh well, I guess now I will just go bask in my negative rep from craigstr....he is an official product tester and "brand ambassador" after all so I am sure I can learn something important from this.

    Yeah, whoever gave me neg reps for such a benign comment definetly needs to do a ball check. I could care less about rep points, it just bugs me when someone tells me to "go away"! I bet he felt really tough typing that on his keyboard.

    I agree! Nobody is arguing that this is something anyone should do.. Just playing with ideas...playing with setup. Lots of people are interested in 650b and there have been several posts in the Knolly forum asking about fitment. I LOVE my endorphin with 26" wheels....but I would see how it rode with 650b if they would fit, just to find out. I would do the same with 29" just to know how it felt....learning is everything :rainbow:

    Tough to say you don't care when you whine about it every single time. No need to respond to this by the way, we've all heard it.

    Just going to add to everyone who says that the fit might not be so great once you ride the bike. My friend got the biggest tires that he could just barely fit on his 29er and they seem to bulge out and catch his seat stays at inopportune times.

    Gotta go with catch22 on this. If a 26 x 2.4 provides the same outside diameter as the 27.5 x 2.1 then it isn't offering an improvement in getting over bumps and holes. IMO, it would be worse.

    How would the 27.5 x 2.1 setup compare to a 26 x 2.4 in the following:

    --Tire deflection at same pressure?
    --Rolling resistance?
    --Traction?
    --Which weighs more on the outside part of the wheel (bigger rim and smaller tire or smaller rim and bigger tire)?

    Definitely not the same as a 26x2.4. The last Chili I built used 2.4 Ardents on Flows and there was ample clearance in the frame...likewise on my buddies (last generation) Endorphin. On my Endorphin (last generation), I cannot even get that same (XC) 650b in the frame without deflating it first, and it rubs as soon as air goes back in. Mos Def a no go on the 650b where a 26x2.4 (minions also fit fine) is good.

    Back to my bigger point: I am not saying a Chili would work well with a 650bx2.1 tire, I was just showing that one could be squeezed into the frame....I would certainly rather run a super fat 26 (HANS DAMPH's are downright filthy on a Chilcotin), but I would also love to ride it with those 650's just to know how it felt. How can one know if they don't try?

    Really? XC race bike? Hardly. Float 36, AM Wheels, Dropper Post, Haven bars, 2x10, chainguide. The idea was a light AM bike I could race at Northstar which is more Enduro type racing. I used the same bike in Super D races too. Never "expected no comments". Never "jumped all over the the OP" either, I just dont understand why someone would stuff larger wheels in a frame and mess up the geometry, why not try a frame designed for the wheel size.

    I'm sorry if my post seemed like it was opposing what you had done. On the contrary to what you may have thought, I'm all for experimentation. I was just conjecturing that a 650b that has the same outside diameter as a 26 wouldn't offer the commonly-sought advantages. However, I think both wheels would have advantages and disadvantages. (Example: I really the 650b mounted on carbon rim with a smaller tire would offer less centrifugal force than a 26er with a large tire, because of less weight out at the edge.) My questions were focused on the pros & cons of same-diameter 650b vs 26er.

    My comments had nothing to do with the "desecration" of a 26er. (I'm not religious; even about bikes.) They were more focused on a wheel-set comparison. Do whatever you want; just be sure to post a ride report!

    My comments had nothing to do with the desecration of a 26er. (I'm not religious; even about bikes.) They were more focused on a wheel-set comparison. Do whatever you want; just be sure to post a ride report!
    No apologies necessary....I just wanted to make sure people know there is a definite, measurable difference even between a small 650 and a large 26 (although every time I look at my endo with ardents sitting right next to my 650b hard tail I keep thinking "man it's so close...maybe they will fit after all!")

    I cut some gauges on a laser to the diameter of a inflated Pacenti 2.1 and 2.3 650b tyre with a 12mm hole some time ago and tried them out on my XL Chilcotin that I have just built up and they both passed the seat stay joke. The 2.3 just clears with about 1.5mm clearance. I'm thinking of getting a set of 650b's for another bike and might try them out on the Chilcotin.

    Anybody have news from the private unveil at Interbike?

    Now I need to possibly add a Knolly Endorphin to my list of 650B lust for bikes. Needs to climb like a goat in gnarly rock and root infested New England terrain so I have much reading to do

    Yeah but what the hell is wrong with us? We both have new bikes and we're already looking at other possibilities

    Would love to try one out and you know at least in New England you're not gonna see one out on the trail very often which I kinda like.

    Seems 10mm makes a difference

    I just fitted a 650b 2.3 TS Schwalbe Hans Dampf/Flow EX/Hope evo pro 2 wheel to the front only on my Chilcotin. The tyre weighed 838g and was fitted with a tube for now. The HD measures 705mm dia when inflated to 26 psi which is only 10mm bigger in diameter compared to the 26" Conti 2.4 Rubber Queen which I am running on the back. Consequently there is a minimal change in bb height and head angle. I was slightly disappointed at first that the difference in diameter was so little. The good thing about it though is that the 650b HD cleared the BOS Idylles without a problem. Should be no problem with the Devilles as well. What I wasn't expecting was the much better roll and grip. Corners really great and much faster and flowy downhill. Seems that 10mm can make a difference.

    It is possible and the only way to verify would be to try out a 26" version of the HD having not had any experience of that tyre before. I wonder, is there somebody out there who has tried both and can say if there is a real improvement with the 650b version?

    How much clearance do you have on the rear chainstay with the 2.4 RQ?

    You know where this could be heading again!

    10mm in diameter, that means only 5mm increase in radius?
    Will that really makes a difference?

    I would need to double check but around 6/7mm I would say.

    If it looks like the 650b HD might fit, then I'm going to try the front on the back, mocking it up using some spacers to convert from 20 to 12. I'll let you know.

    The BB would be 1/2" higher for a full conversion and about 1/4" higher for front wheel only.

    If you have a Chili I would just run a 650B upfront and enjoy most of the benefits.

    If you are looking to buy I would wait for the 650B Chili to come out and not deal with any compromises.

    I'll need to get back to you on that with some measurements. There's only a 5mm difference in wheel radius so the bb will not change that much.

    Front only was my main aim, but I am curious to find out if the 650b HD will clear on the back. If it does clear it will be very tight I think. We shall see.

    That's exactly what I plan on doing, but won't have my wheel for a couple more weeks!

    Going to be using a Fox Float 36 RC2 up front, with zero stack Works Comp headset (1 deg).

    Just was very curious also about the rear clearance.

    PS. the HD is a huge volume tire on my Rip9.

    Just doing some research and ill be honest i have limited knowledge regarding 650B rims. The chart below was posted by another forum user. It appears that options are limited even having searched the net repeatedly..

    If choosing a 650B rim for the front for heavy AM use, (NOT XC trails) can anyone recommend a strong 650B rim that is 36H with a welded not pinned junction? There have to be more options out there other than whats listed ...

    Can anyone share their experience please?

    I'm using Flow EX 650b, 32 hole, around 25mm inside, 28mm outside. Laced to Hope evo pro 2 front weighs 900g. Coming next year are the Syntace 650b rims in different widths, 30, 35 and 40mm. Also the Pacent rims are getting good reviews. So plenty of rim choice for heavy AM use I would say. At this time I would say the choice of tyre for AM is limited to either the Schwalbe HD ( availablle in 2.25 and 2.35 and three types including a DH version) and the Pacenti Neo Motos in 2.35. I'm really liking the 2.35 HD Triple Star (838g).

    Thanks fellas. 650B forum is fairly hodge podge ATM but will relook there. Wheelset combo will be a 27.5" up front and of course 26" rear

    26" Rear Wheel (current):

    Mavic 721, CK Hub w/stainless steel cassette body, DT champion spokes & brass nips, Conti TK 2.2" black chili

    27.5" Front Wheel (Proposed)

    Velocity P35, Hadley hub, DT competition spokes & brass nips, not entirely sure about tire clearance so will do more research regarding this. Front wheel will be on a 2011 Fox 160mm Van R2C Coil. Tires of similar thickness across and weight would be ideal. Comboing a TK in back and a HD up front felt decent enough when I tested on 26" rims.

    In the slack position I am already having pedals strikes with my 175mm cranks despite a Conti TK 2.4 up front and a Cane Creek external lower headset cup. Once I am done building the 27.5" front wheel I will revert back to the steeper frame setting and see how it feels and post back.

    Appreciate the help once again!

    PS. Still hoping for a new Delirium.

    The SC Podium we were experimenting feels somewhat long for my usage intentions despite the -ve angleset cups. Great going down however.

    650b rear will not work!

    No one read eadubber's first post. Knolly has a pivot on the chain stay. If you hit a bump, the tire will hit the chain stay. It has nothing to do with fitting the tire on the bike stand. Try moving the chain stay all the way in on your Delirium-T and go for a ride - you will end up with slicks! I'll bet ya that is why Noel dumped that feature.

    Yes, agreed. This actually is for a FRONT wheel only application. I edited my earlier post to make it clearer. Thks

    Depends. Hans Dampf 2.35 SS, Nobby Nic 2.35 SS, Neo Moto 2.3, Ardent 2.25 EXO, Nevegal 2.35 might not be crappy low performance tires for everyone. You can buy those today + a bunch of nice high performance XC tires.

    Those Nevegals are impossible to ride and will kill you twice, that's on Ridemonkey if you don't believe me.

    I just measured the wheel height on my Endo26:

    Industry Nine XC rim / 26"
    Schwalbe 2.35 Hans Dampf (tall tire, very high volume)

    = 27.25"

    Not sure what you're looking for in tire availability but some of those tires listed above by StiHacka are excellent and that's just a short list of what's available and/or coming very soon. I've got a new set of 650B Nobby Nick SS tires and the things measure almost 28" tall, roll awesome and grip rocks like no body's business. The HD is a terrific all around tire as are the Neo Motos. The Nevegals are a love/hate for many people. A bunch of guys I ride with seems to really like them for the trails we have here in New England. Never tried em myself. Educate yourself before before spreading miss information to those trying to get a handle on this 650B size. Way to many people doing that who either resist change or don't understand how this size will improve on a 26" bike pretty much without the compromises of the 29'er.

    Need more proof have a look at this

    Hi skidad, I measured my 650b 2.35 HD's at 705mm, suprising that the NN's are bigger.

    Yeah, I was a bit bummed to see the HD measure smaller. I've taken the tape to the NN a number of times to recheck and I still see close to 28". While I loved my Neo Motos these are faster, roll better and stick to rocks better. I'd give the cornering edge to the Neo's though until I set up the NN tubless and lower the pressure to see. HD on the front and NN out back might be the sweet spot.

    Awesome!

    Pacenti should have the 2.4 Mega Moto in production soon also. It's huge from the pics I've seen.

    Kirk will we be expecting to see compete single 650b wheels (not just wheel sets) available on bikelugs soon? I recall a mid December time line.

    My 650b Hans Dampf (2.35") tire just arrived. Its very probably not going to clear the Fox 36 Vanilla currently installed. The 2.25" version has yet to be launched although i'm told before the years end. It will be either this or the 2.3" neo moto if the 2.35" HD fails

    Planned front rim as it stands right now is a Pacenti DL 31 (36H). Welded, eyelets and anodized black finish, something the P35 and Blunt SL didn't have.

    I would be VERY surprised if that didn't clear your fork. The 36 forks have more arch clearance than the 32's from what I read and @ 705mm diameter it's just slightly larger than a 2.35 Nevegal which people are using on the 32 forks (although when new probably rubs the crown at bottom out on the 32...but who gets full travel from a Fox fork?)

    Give it a try and I think you'll see it fits ok. To check crown contact of course you need to remove the spring which you should do to be safe.

    Thanks for that Skidad, it's reassuring to know. I'll post back with some visuals once I have wheel built and tire mounted.

    Regarding a coil fork and crown clearance - would you feel that with an air fork this is more imperative safety wise? IME even with correct sag dialed in and compression and rebound fully open I have yet to fully compress my coil forks (5-7mm residual). Unlike air forks once bladder is emptied there is "nothing" within the fork leg/stanchion as compared the "material spring" in the coil fork. Thinking aloud here...

    idk. every fox air sprung fork i've ever owned never reached full travle while riding unless i ran the air so low that it was useless. i think under riding conditions air forks have a harder time bottoming out if set up with proper sag. one of the downsides to an air fork is not reaching full travel. at least as far as i've experienced

    Just did a rebuild, my van lowers have never slid all the way up. crown and arch seem to have the same clearance

    The coil equivalent to emptying the bladder is undoing the top, above the spring. IMO, if you keep a substantial amount of air in an air fork you would have a similar experience (i.e. not being able to bottom it out).

    That said there are two possible reasons why you can't get that last bit of travel in a coil fork:

    1) Spring coils touch before full compression which would be by design. You could check this by putting the bike on stand, making sure that the stanchion is fully extended and check stanchion length versus the fork travel spec (i.e. a 170mm travel fork might have 177mm of total stanchion).

    IMO, I would prefer a design that had a bit of extra stanchion so I wasn't buggering up my seals on a hard hit.

    2) Not applying enough force. You could test this by getting a lot fatter and doing a few front-wheel-first landings to see if you can bottom it out.

    Another option is using a tie-down and suck it tight. You may need a ratchet-type tie-down to generate enough force because most coil forks have bottom-out bumper which is hard rubber and will take a lot to compress. (The force is linear UNTIL all the spring is compressed and then ramp very hard.)

    Edit: you may need to purchase a new bottom-out bumper if compress it as far as possible. Good luck!

    I dont know that I would test it that way, are you suggesting this with the spring still in the fork? Sounds dangerous if so.

    There are many reasons for not getting full travel, here are a couple more that come to mind.

    Too much oil in the Dampener.
    Fork may have some kind of bottom out resistance feature that is just too hard to over come.
    Spring rate too high.

    Yeah, whatever. What will the BB height be if I run 26" wheels on the 650Bilcotin?
    Nice KOM, sorry about your penis.

    Need to see video example of this experiment.

    What's that about curiosity and dead cats? LOL!

    Sadly, I've done many front-wheel-first landings but never for the sake of science. I'm just not that dedicated.

    I have tried the tie-down strap (no ratchet) thing, while checking out the internals of a dampening circuit. (I didn't have a wrench--crescent or other--big enough to take off the spring cap.)

    BTW, I didn't get full compression.

    I hadn't considered too much oil in the dampener side. I guess that could do it, though I would guess that you would blow your fork seals.

    BTW, I was suggesting the tests in #2 with the spring in the fork; but as jokes. I wouldn't suggest that anyone follow any mountain bike related advice if the poster says "use a sledge hammer" or "use a ratchet strap."

    Just measured a kenda nevagal 2.5 x 26 @ 28psi = 682 mm diameter. The wheel is off my Knolly DT with a RS Totem and there is only 20mm clearance between tire and fork crown. A 650b Hans D would only leave 8mm clearance on the average 26" fork.

    Me - but I wouldn't neg rep someone because they didn't want a 650B bike.

    +1 - agreed - which is why I'm gonna keep riding my 26er until Knolly or someone else comes out with a 650B frame I like that was designed to be 650B from the get go.
