In the spirit of MTB, I'm considering doing a ghetto tubless setup on my new 700c wheels... I don't see many roadies doing it and I'm wondering if I'm missing something.

...then again we're all risk takers here, amirite?

Anyone else seen/heard about big problems doing this shi....?

You will most def need tubeless specific road tires. At 100 psi, things are a little different than 30. Read this: http://www.bicycling.com/bikes-gear/new ... o-tubeless

It's doable alright. I did it a few years ago, but didn't find it to be much of a benefit.
If you get flats often, then it's great, but then again, so is a dash of Stans in the tube.

If you wanna try, make sure to use Nomex or something similar, and not just those usual tubeless rim strips. They will not stand the pressure.
Also I have gotten a healthy respect for the heat rim brakes induce, thus again, Nomex film is the thing to use.

On my rim brake MTB, using Nomex saved my pretty face, last time I was riding the mountains in Austria.
Something began to smell funny. After telling the Mrs. to get off and walk (like 35 degrees downhill, and she's not all that experienced in that regard), while standing there chatting, I thought I'd check the temp of my front rim.
I burned my fingers :D

This is more of an issue with a road bike than a MTB, so watch out.

Sooooo......... since I got my Planet X wheels (great buy for the price) and have tires mounted those mounted properly (i.e. with tubes), I tried to convert the Spinergys to tubeless.

Stan's tape etc went in nicely but I couldn't get it to inflate at all. Hmm... maybe it's the tire (cheapie Conti Race something)

To inflate them first time, I found that first inflating them with tubes, and leaving them like that for a couple of days, made them get the right shape.
Also it helps to wipe latex on the edges of the tire and the rim, and leave it to dry up.
I did it with el cheapo tires as well, with no particular difficulties.

These guys were inflated with a tube and ridden on for 2 weeks. Still cant get it to seal enough to inflate (see the tube on the floor?).... here's pics of the prep.

Lighter fluid time? lol

Shibi - try pinching the beads to the center of the rim so they are sort of closed on each other as best you can. Then, pour a little Stan's between the bead and the rim lip all the way around both sides. Then, with the valve in the six o'clock position, remove the valve core and put some Stan's in the tire.

Put the valve core back in and pump it up with the valve in the six o'clock position and the wheel off the ground.

OK... pumped it with an air gun without the valve and it inflated right. Remove air pressure and the bead falls away immediately. Don't think stan's juice will act as a temporary glue (or will it?)

If you let it contact the air when humidity is present, it'll dry up like any other RTV. Should glue fine.

RTV... now that's a thought... I got some of that laying around. Should work to hold tire in place and the stuff would remove easily if the tire has to be changed out.
