    Running (older) Mavic SUP rims tubeless...am I gonna die?

    RIMS, not tires! (Typo)
    So, this is self explanatory. I have a Mavic SUP (road) wheelset that I want to convert to tubeless. It is probably 15-16 years old. We had no problems converting mountain rims to tubeless BITD, but those are MUCH lower pressures.
    Anyone have real experience with ghetto tubeless for road/CX?

    I want to try this with tubeless tires, obviously.

    Researched a bit, the answers are all over the place.

    Ahhh, its definitely a no go. A tubeless rim is different from a normal rim. Your old rims have nothing to lock the tire in place. Its not as simple as just using the proper rim strip to provide the air tight seal & you're a go.

    You could try it but the tire would most likely just blow right off. If the rim does't say tubeless ready, then there's a good chance you may die. So go for it.

    Right...but that's for Mountain (lower pressures). I set up hundreds of wheels like this at my old shop...

    'brifter' is a lame word.

    Don't do it. Good reason it's called a 'hack'.

    sorta fitting* to make a tubeless hack with a hacked tube, though.


    * or ironic, whatever.

    Some hacks work, some hack don't. This hack may kill you. As the saying goes "Don't try this at home".

    Upon further reflection, I think any fast section I would be riding on (and there are lots of FAST sections around here) I would be contemplating my mortality at 40 mph.
    Too scared of the consequences.
    Not gonna do it.
    Might rebuild the white industry hubs with tubeless rims, though!

    EDIT: What I'm finding, however, is that rim brake tubeless rims are nearly impossible to find at cost.
