    has anyone made non-tubeless- tubeless like this?

    Used a 26" tube, slit down thew middle mounted on 700c rim (like fat Stan's strip)
    mount tire and install Stan's goop
    inflate and let tire seat
    trim tube to rim (tight so brake shoes don't hit excess)
    let sit to see if the tire seals and holds air

    I've tried using 26" stans rim strips on 700c rims with cross tires. It seems to be difficult to seal, worked well enough to ride but lost air over a couple hours. Your idea may work better and as with all stans type systems it is dependant a lot on tire/rim interface.

    I'm really tempted to do it since I already have 700c (29") Stan's rims and strips. Many tires with weaker beads do not do well tubeless, especially with the larger diameter of 700c wheels. I like my Michelin Mud's a lot but Stan does not recommend their 26" tires for tubeless conversions, so I'm pretty wary of trying it with a 700c tire. Kendas work well for 29" conversions, so I may try it with their Kwick or possibly a Hutchinson tire. There would be some definite advantages over Tufo, mostly not losing $75 everytime you get a >2mm hole in your tire. I'll post here if I try it.

    It's a problem with pressure. You cannot use these tubeless kits at pressures required to run road or cyclocross tires. Max pressure is like 40psi.

    Name me one CX racer that uses 40psi when he tries to actually be fast.

    I'll some day finish the build of my ultralight 29" stan's wheels. I'll be interested to see how they'll take a fast CX tire like, say, a Schwalbe Racing Ralph 35mm. The rims are wider (24.4mm), which might add stability and some volume, whether that's good or not. Stan's rims come with a special rimstrip.

    NEVER use Michelin tires with DIY tubeless systems! Most elastic beads I've come accross. Latex 150dB facejob guaranteed. I know.

    If a CX tire can be made to work with 29" wheels, you'd have a very light and useful rim+tube(less)+tire combination, as the rims are ~391g (average of mine), and MTB-sturdy.

    I'd personally prefer a 29" version of the Eclipse strip for my rims, the system makes more sense theoretically. I once use a Mavic 26" strip in a 700c Open Pro rim, and despite ignoring the double eyelets or instructions, it actually worked quite well. It leaked, as it was not a serious attempt, but it showed potentials. Don't try double eyeletted rims for tubeless and actual riding, ever.

    when i was toying with this idea, i emailed stan. they said to use the 29" set up for cyclocross. i then forgot about the project. may be it's time to get back on the horse.

    pretty much every one of them (fast guys...) uses less than 40, unless the course is exceptionally smooth. i weigh close to 160 and haven't used 40 yet this year. wunlap, skinny guy that he is, uses between 32-36 usually. we both run tubulars, if you didn't already guess that.

    Ran 38 and 35 in Tufo's on Sun.

    On a bumpy course it was lovely.
