    Which Fox Fork will 650B?

    I recall seeing in one of the threads someone (probably Kirk) was able to just barely fit a 650B wheel in a Fox Fork. I can't search for "fox" so it is hard to locate.

    Can anyone report if there is particular year or version of Fox Fork can fit the 650B wheel and tire?

    It would be useful to have a location on the net that keeps track of what 26er frames and forks are 650B friendly? There must be more than the Surly 1x1.

    To the best of my knowledge all current Fox forks will accept my 650b tire with about 7mm of clearance. The X-Fusion"Velvet R" fits the tire with gobs of clearance at about half the price of the Fox. The Maverick forks would also work with a modified travel reduction kit about half the length of the "29er" kit, the Lefty and U.S.E. "SUB" for would also work with some minor modifications.

    As for frames, there are likely dozens that could potentioally work for conversions. The Heckler, Rush, Prophet, XAM, and problably quite a few others would work very well.

    The 2007 Fox F80 I used on my 1x1 conversion actually looks like it has more clearance than the WB 100mm IMV does on my 29er, by a mm or two. Maybe I'll try to get a picture of them side by side one day.

    Manitou Minute?

    I have a SC Heckler with a Minute One fork. I am interested in trying out 650b but don't know if it will fit up front. Any thoughts?

    650 b rim choices

    Kirk,

    I notice on your blog site http://650bpalace.blogspot.com/ that the tire cross section references a rim which is 18 mm in width. Is the rim and ERD noted that of the Velocity Synergy 650 b rim?

    If so how does this rim compare with the cross section of the Neo Moto when mounted to the Velocity Blunt rim (28 mm) wide?

    Finally, do you know the weight difference between the Velocity Synergy 650b rim and the Blunt(at 480 gms) ?

    I'm fairly confident it would fit just fine on a 2007 32 TALAS. Below is a pic of the clearance on my 07 32 TALAS R with a 2.25 Schwalbe Albert.

    I don't think it will fit in the Manitou fork... I have a "Black" here and the tire hits the arch before the axle gets anywhere near the drop out.

    Damn them and their lack of foresight into an obscure 3rd standard! Actually, damn 650b for being a third* to begin with.

    *Reference to the book Ender's Game, which is fitting as almost nobody knows about it. Oh, and if you can't pick up on the sarcasm here's the obligatory "j/k" for the believers in the crowd.

    Other 650B tires avail?

    Kirk, I tought I heard you had three tires coming out: Neo-Moto, a 52mm Marathon tire, and a narrower 40mm Cross tire. Is this true? Do the sknnier tires fit different forks? I was thinking about something skinnier maybe even 1.95 for my racing XC machine.

    I do, but these things take a long time to develop.

    The current tire, the Neo-Moto is available now directly from me. By Jan / Feb it should be available through every major US distributor to every LBS in the country.

    The "Quasi-Moto" is my next tire. It's a 2.0" semi knob racing tire. The samples should be ready in March with production tires landing in June / July.

    Shortly after that will come the "Mini-Moto" a 43mm knobby for use with the worlds millions of existing 650b bikes. This tire will work perfectly with bikes like the Rivendell Bleriot, Suluki and Glorious, as well as the Kogswell and Rawland bikes.

    Some time down the road I will do the "Muddy-Moto" wet condition tire too.

    I don't plan on switching over to a 650 setup, but I think you guys might be interested to know, that the 06 130mm Minute Twos have gobs of clearance. I have a Maxxis Advantage 2.4 mounted in a 06 Minute Two and there is still about a half inch of clearance between the tire and arch.
    These by the way, are good forks, although I don't know if you can still get them by mail order. I purchased mine at Pricepoint and I know Jenson used to carry them.

    I measured that Maxxis with a radius of 344mm. The Neo-Moto is 352mm.

    If you have a full 1/2" (13mm) that leaves just 5mm of clearance. Manitou says 8.5mm is the minimum for safe operation.

    Yep, I just measured mine and came up with 343mm which is close enough. It's also a brand new tire with no wear. It's also one of the larger tires on the market.
    Some of the fork makers say you can run a little less clearance than my Manitou, but even with 13mm clearance, I get significant numbers of rock jams here in the desert.
    Something for potential experimenters to think about.

    Hmmmmmm.

    Hey Kirk which generation Heckler are you talking about ?
    This can be great, just get the frame and build it with the 650b, I really like the Hecklers and to convert it with bigger wheels ... maybe this is what I'm looking for.

    Has anyone had any experience with the older variety (the ones with canti mounts) Fox forks? I've got a rigid fork that I know will clear the 650b, but I'd like to run a sus. fork (and the Fox is all I've got).

    older fox forks

    i just got back from a ride on a converted kona unit with neo-motos and what is i think a 2004/05 fox vanilla. the tire has penty of clearance in the fork, and barely fits with the rear wheel jammed forward, so if youve got a good gear ratio and can slide it back a tiny bit, there is no problem.

    old fox + neo moto

    here it is! photographic documentation! the "conversion" was painless, there were no issues whatsoever

    on a side note, the rims are sun cr18 from velo orange, and the tires fit with little trouble. there are easier combinations, but there are many more difficult combos too, which was a surprise considering velo orange says that it can be tough to get tires on these rims.

    Not sure if you're still reading this thread, but by rock jam do you just mean rocks getting carried up into the arch (causing some chipping and crunching), or actually getting a front wheel lockup due to rocks jammed between the tire and arch?
