Ghetto Tubeless
« on: June 11, 2012, 04:56:45 PM »
Anybody have experience with ghetto tubeless? Google is full of people who love it and people who hate it, and it's hard to get an idea of how many of each there are.  I'm pretty sure I'm going to pick up a set of tubies and put all round tires on them, but I'm also thinking about setting up a mud wheelset with ghetto tubeless, since it costs basically nothing.

Do you mean ghetto as in "non-UST", or ghetto as in "not Stan's or Joe's"?

If you just mean non-UST, I just built up a cross bike with Stan's tubeless.  In the previous year of running those same wheels tubeless on my 29er, I got exactly one flat, a big sidewall tear.  I booted it, put a tube in and rode another 10 miles.

I've only got one ride on the CX bike with the tubeless wheels (just today, as it happens) but IMO it's spectacular.  I did a few miles of somewhat technical single track even.  I'm running 40psi in 33c tires and could easily go down to 30 if conditions warranted.  (I would run 2.3 MTB tires as low as 18psi in wet climbing situations.)  I love the feel, especially when climbing rough terrain, and I love the weight savings.  You will want a compressor though.

Ghetto as in non ust using a tube cut in half as a rim strip.

This perversion of tubelessness is interesting to me....


Granted, had no issues running upper 20s in front, low 30s in back, for PSI on my 35mm CX rubber last year...

I'd just like to understand. Why would one use a cut up tube over a proper rim strip?

To save $5, is all I can come up with.  People use "ghetto tubeless" to mean anything from a DIY job made with old cut up tube parts to a full Stan's or Joe's kit, but at a minimum you need to buy some sort of sealant, so seems to me you might as well buy a purpose designed rim strip too.

Supposedly for cross tires the tube under the bead makes it less likely to burp. Also, to be cheap.

LBS, guy suggests to put something called Tom's (i think) in the tubes on my cross bike. I think I'm going to have him do that on Monday. The first cross practice is this Wednesday.
Anyone think this is a super bad idea?

No, I think it is a fantastic idea. It obviously doesn't help against pinch flats, but will help with goat heads or other puncture flats. It adds a little weight, but worth it. I had a few flats early last season and then put Stan's in both of my tubes and had pretty good success for the remainder of the season.

P.S. Who is your LBS guy?

i tried a tubeless recently using gorilla tape on the rim, a valve stem cut out of an old tube with some double sided duct tape as a gasket, and stan's to seal everything up. works well enough that i was able to dent the rim and the tire stayed put. also got a puncture last night which sealed itself while rolling.

and i was able to seat the tire without an air compressor but it does require some creativity..

Any of you guys know if you can do tubeless setup on some 2010 (I think) Mavic Kryrium Elites?

i think the tire selection matters just as much as the rim. i've read, although have no real experience myself, that wire bead often works better for ghetto tubeless conversions. my experiment was with a wtb i19 29er rim and schwalbe's racing ralph evo tires. the rims are meant for tubeless using wtb's "tcs" standard. their version of ust i guess... the tires are not meant for tubeless. so far it works though.

fwiw, this guy had trouble with the krysiums http://forums.mtbr.com/8404052-post2.html

I decided not to rig anything up so i haven't looked in a while, but I think i remember reading ksyrium's have a relatively deep channel and require a lot of building up to be secure ghetto style.

I would think Ksyriums would make awful cyclocross wheels. Radial, low spoke count, flat section rim.
