    For instance, an ExiWolf 29" x 2.3" on Salsa gordo is 28.5" OD. 723.9mm OD. If you add the numbers it appears it should be 738mm (622mm + 116.84).

    15-20mm will make a big difference in terms of clearance.

    thanks.

    Ya, have to wait and see actual results. The "2.3"" stamped of the side of a tire often doesn't measure exactly 2.3"... sometimes one brands 2.3 will fit and another's won't. Plus you don't know who or how they measured them. Have to take the tire size thing with a grain of salt 'till you get the goods in hand.

    Take the sideview picture at;
    http://24.media.tumblr.com/tumblr_m7...9plo2_1280.jpg

    Open it in a photo program (I use gimp) and measure the # of pixels for the overall outside diameter of the rim at the lip (know deminsion is 633mm, NOT the 622 bead seat specificaiton which is not visible in the picture). Now measure the pixel count of the OD of the tire on same rim and do the math to get tire diameter in mm. I get 765mm (30.1") for knard, basically the exact same outside diameter as a big fat larry so any frame that can use a BFL should do fine with diameter of the knard. Very likely that whatever maximum size limit of the tire manufacturing machinery that limits diameter of BFL to 4.8" is also identically involved in limiting OD of the knard thus they are same OD.
    I also found a good front shot of the knard tire, scaled from pixel measurement of the 44mm headtube and measue the knard tread width as 81mm / 3.2" .

    If it is a typical Surly 27.2 ID tube, you can always run a KindShock post, they go down to 27.2. I haven't had any troubles with mine, an i7 remote version.

I'll have to wait 'till I have a tire/rim in hand to mesure myself. 30.2 or 30.3 might barely fit, but 30.5 just doesn't look feasable for the shorter CS'd bikes. Might fit on the 907... they're quite a bit longer. It's all good! I like my short CS's. And I love my FB's just like they are. If the Krampus works out to be the cat's meow for certain purpose's, just have to go w/ a complete bike... and, like I said, curious to see how this new format evolves... the 50mm rim is spot-on for all around riding w/ a 3" tire (IMO), but a 65mm rim would bring those beads out closer to the width of the tread and increase it's floatation by leaps & bounds (all around dirt handling being the trade-off). I'm guessing we'll also see some ALU and TI offerings from other builders as well... FUN STUFF!:thumbsup:

    Re-measured last night; On the Fatback I'll rub the derailleur arm and cable at 30" almost exactly; On my custom it will touch the CS brace and the cable at 30 1/4" so if it turns out that they're 30.1 they might fit on that one.

    Changing crankset to a MWOD, or using a adjustable chainline Profile crankset with a wide spindle, or adapting a 148mm wide ISIS spindle to the 73mm shell could likely allow a Krampus owner to widen the crank chainline enough to get tire clearance for an inner 22T chainring and have a useable middle chainring 2X setup.
  • 07-26-2012
    Dr Feelygood !
    Or using a 83mm by 133mm long FSA ISIS BB and spacing it over if you need too ?

    Did this on the Fat Klein and it allows granny ring with enough clearance for Larrys on Trailtec 47mm wide rims.

    Should work fine with RH's and Knards :)

    I know this is a little off topic, but as per your blog and your thoughts on XX1, are the XX1 style
    chainrings really required for operation? Yes I understand that chain rentention may suffer, but
    required? If nothing else, run a rear cog as a chainring, would take some work, but seems very
    doable? A 26T would give something like 77.0-18.7gi with a BFL

    I think SRAM missed the boat with their choice of BCD and dedicated cranks.

    Not necessary but performance will likely suffer going with standard rings. Haven't tried it yet but it seems like a good idea to me.

    Making them proprietary is not such and issue since they have designed a full system to work together and to make it work the best having all of it is probably better. Plus like G-Ted said you can buy a different spider if you want to.

    Does Big Apple make a 29" fat street tire or something? If so any 29er tire will fit on the rims. Even skinny ones. But fat ones (2.35+) will fit better.
  • 07-28-2012
    byknuts
    yeah BA;s would fit for sure.
    big apples are 2.3" slicks made by schwalbe, but they're VERY large air volume so they could spread out quite a bit on RH's.

    try searching for "hookworm on large marge" pics. hookworms are 2.5's but the visual effect of big apples on rabbit holes would look fairly similar. (since the rabbit holes are 50's and the LM's are 65's.)

    Still no one has answered the question though; will a regular crankset with a granny ring (22t) have chain/tyre clearance on this bike? no 22t front ring capability with a 34t or more usefully a 36t ring will allow this bike to climb anywhere usefully, no matter how hairy your chest is :D

    When many people built their first 29ers they stripped a hardtail and bought a frameset/ rims and tyres. Once the wheels were laced they built the bike with remaining parts, so a cheaper build was possible.
    An expensive crankset like a 73mm MWOD makes this not a very cheap build then sadly.
    Guess that will be answered when folk get hold of one and ride them a bit.

    People have also commented on my FB page about the Krampus lack of 22t granny ring compatibility and lack of tyre clearance for mud...

    No one on here seems to want to address these issues folk are asking?

    Lets see some mud plugging low gearing pics please or film! :thumbsup:

    I haven't seen the bike so I don't know but using a 68/73 BB and a 135 hub may make it so the wider tire won't fit but probably not. 3 inches is not that wide. With 3.8" tires using a 100mm BB and a 170mm hub makes enough room for a triple with no funny Pugsley type offset.

    On fat street tires. I wish they made a 2.5" Hookworm in 29" I used to run the 26er version on a commuter bike before it was stolen and they are great tires.

    Let's hope the fatter 29er tire revolution is on the way. The extinction of DH Dissents was quite a blow to the off road world imo.

    Here is my 29er DHer that I just built with Dissents.

    Well Coastkid, all I can say is that I don't have a CLEAN full gearing range on my middle ring with 3" gazzis.
    Orange patriot, 40mm rim, saint cranks, spaced as far out (all offset spacers to the drive side) as I can and the chain JUST rubs the tire in the granny rear.
    it's acting as a sand shave really... bollox for the chain.

    I'm expecting you'd need a longer than (current) standard bb axle. but only by 5 or 6mm, nothing crazy.
    some cranksets just have an inherently different chainline so if there were a better database for that sort of thing to point you in the right direction, that might be all you need.

    gazzis aren't knards though so take my "knowlegde" with a grain of salt.

    Spreading a 2.35" tire across a 50mm rim is certainly possible. It may look like a low profile tire. and lower pressures may not be a good idea. Also, all of the previous depends upon a solid fit between the RH and the tire. A loose fit would be a bit sketchy, I think.

    I don't think ANY Dissents made it to the UK :(

    The cheapest chainline fix is the spaced 83mm ISIS BB as it will clear Larrys on 47mm rims.

    Are you saying space it out on a 68/73mm bb shell? I've thought of that but didn't know if it would work. That's quite a bit of spacing.

    This is exactly what I ended up doing on the Fat Klein (73mm BB shell).

    It is only 5mm each side, so two 2.5mm spacers on the drive side is all that is needed.

    FSA BB is 133mm long (ISIS).

    Running 2.35 WTB Moto Raptors on a 26"x48mm trials rim worked fine for me and I think for lots of people on this forum. Some people were even putting Big Apples and Hookworms on 65mm Marge rims and claimed they worked fine.

    I just measured a buddies first gen. Sultan and it has 15 inches of clearance exactly at the chain stay yoke and 15.25 at the seat stay...no interference with seat tube that I could detect. It may fit but just barely...if the Knard wasn't so wide that is...the yoke at the chain stay is only 78mm. Seat stay has room to spare at 84mm.

    Close but no joy for the first generation Sultans with horst link rear end.

    Your Rabbit Hole Looks Knardy

    "We've told you most of the pertinent details of the new 29x3.0 Surly Knard tire. It'll be about 820g for the 120tpi folding version and pretty close to that for the 27tpi. It's got blocks and whatnot for a tread pattern and it is 100% the best thing ever in the history of the universe and if you don't buy two you don't know anything about anything and you're a big jerk. It's also a very nice tire.



    So nice that we're going to make it in a 26x3.8" too.





    THE RABBIT HOLE

    It's a 50mm rim built for getting wide with 29ers. It will fit 29" tires down to about 2.4 or 2.5" and - of course - up to the Surly 29x3.0 Knard with which it was tandemly designed. It's got all of the nice features of our fat-bicycling rims - the cutouts for weight savings, the 64 spoke hole pattern for symmetric or asymmetric builds - but it's, you know, bigger in the circumference sort of way. It will weigh about 700grams and will help you be a better person.

    It's a single wall rim, but only mostly. There are actually internal spaces near the sidewall areas that make it a bit of a hybrid between single wall and double. Cut one in half and you'll see.

    This sucka is going to come in traditional light-sucking black or in fancy shiny silver. Oh yes.



    Here are some numbers that might help you decide if Knard or Rabbit Hole are right for you:

    The Knard 3.0 tire on a Rabbit Hole 50mm rim will be 75.8mm/77.7mm (casing/tread) wide and will have a diameter or 779.4mm (at 19psi).

    The Knard 3.0 tire on a Velocity P35 will be 72.6mm/76.7mm wide and have a diameter of 778.6mm.

    A Schwalbe Racing Ralph 2.4" tire will be 66.0mm/59.2mm wide and have a diameter of 752.2mm when mounted on a Rabbit Hole rim (at 35psi).

    A Continental Trail King 2.4" tire will be 65.5mm/57.1mm wide and have a diameter of 759.5mm when mounted on a Rabbit Hole rim (at 35psi).

    (The above numbers, as you may guess, will have some plus or minus to them when you mount up your own tires, because that's how the world works Ricky.)



    That's what you get for today. Thanks for hanging with our scribblings this week. Please let us know if you have questions about any of this, ok?



    Thanks,

    I rode one this week... Not convinced.
    Is it a heavy and stable(slow) 29er or a sort of fat fat bike? Felt like a little bit of both and the bad parts of each. Is it fun? sort of, but I don't see me getting one anytime soon, I would get a 26" fat bike first.

    Interesting! Haven't had a chance to ride one yet. Had a friend (who also hadn't ridden one) tell me I "need a Krampus... it's the best of both worlds" (refering to 29er's and fat bike's). He was assuming of course that it couldn't be the worst of both. Sometimes mixing all the ingredients you have together DOESN"T make a tasty dish. Only time will tell. Going to have to "taste" this one for myself!! Cool that they're planning a 26 x 3.8 Knard. Can't wait to see that!

    I see the pre-production 26 X 3.8" Knards are being ridden. Saw a pic. Looks pretty flattish, not so rounded like the 29+ images I've seen. But it could have been on a hundy too, so it is hard to say. The rim was a wide one.

    I'd rather have the wider one myself, the 3.8"er. A 3.0 does me no good at all.

    This looks like the surly limited edition new "Krampuss"

    There is a really great pic of it on Singlespeedcycle.nl or something like that.

    what do you guys think about a conventional 26in fatbike back wheel and frame with a 29er+ front wheel? Will it work? no snow here, just thinking about a fun fatbike for slow technical riding and some singletrack

    Should work fine with the right fork.

    Yes, it works just fine :thumbsup: Mine is a Schwalbe RacingRalph 29x2.4" on a Salsa Gordo rim (35mm wide). This combo rolls as a front wheel of my good old Pugsley through the summer months, in pair with Endomorph on normal 80mm wide fatbike rear wheel.
    In fact, I prefer this set-up for the summer: less rolling drag, less wind resistance, no self-stirring of the front wheel (seems like dealing with "self-stirring" of the rear is much easier for me). Less weight also (could help for technical uphills)! The diameter of my 29" wheel is only 6mm bigger than the rear, so no problem at all for the geometry. Traction is excellent and floating is good enough for occasional beach riding and even for very sandy uphills. I normally keep air pressure in the front 29" 1.5 times that of a rear 26”.
    The only problem is an offset fork and so offset front wheel with non-offset rim. Spoke angles on both sides are fine with DMR single-speed hub, but I had to change front disc to 200mm one because of some minor interference of the spokes with brake caliper. Also modified the later (Avid BB7) a bit. ;) Now its fine. :thumbsup:
    P.S. Yes, now I see 29+ in your question. I’ve got no idea about fork clearance with this new Surly tire (never saw one), but I wouldn’t do this on Pugsley due to geometry change (slack top tube angle is not good for technical riding). Mukluk or anything else with longer fork could be a chance though, better with a change of the fork to somewhat shorter one.

    You should probably have quoted a bit of the reported thread because now it's been removed, you look like you're pointing at another one. :)

    You've rumbled my cunning plan to chip this thread away post by post :D

    Edited my post for clarity.

    The whole of MTBR is getting hit pretty bad by spambots at the moment. The mods usually delete the post and the spammers account.
