Chubba Posted May 31, 2011 Posted May 31, 2011 Broke my AC tubeless valve while pumping my tire. Did not fill me with to much confidence how easily it snapped off. So my question is, what is the best valve system to use or are AC the best? http://www.cwcycles.co.za/product/american-classic-tubeless-valves
CAAD4 Posted May 31, 2011 Posted May 31, 2011 Did the whole thing break or just the thingy that you twist open?
The expat cyclist Posted May 31, 2011 Posted May 31, 2011 Did that happen using a floor pump? I hate handpumps. I use a bomb rather in case of emergency and only use the pump if the bombs blow up.
Trance Dance Posted May 31, 2011 Posted May 31, 2011 If its the twisty thing, i fixed a tubless valve that broke recently by taking out the twisty thing from an old tube and stuck it in. - Works!
pauloc Posted May 31, 2011 Posted May 31, 2011 Further to last post... I've used Stans yellow rim tape, valves and sealant since going tubeless and never had any problems. The other day I couldn't find stock anywhere so I bought some American Classic rim tape out of desperation. Didn't stick to the rim as nice as Stans and when I added the sealant, it managed to work it's way under the tape where it overlapped. The tape also tore in half where the valve goes, so I won't be using AC tubeless stuff again.
dirtrider Posted May 31, 2011 Posted May 31, 2011 Just cut my toobeless valves out of an old tube I picked up in any race I do .
Chubba Posted May 31, 2011 Author Posted May 31, 2011 Did the whole thing break or just the thingy that you twist open?the entire valve stem, snapped off just above the rim.

CAAD4 Posted May 31, 2011 Posted May 31, 2011 Is it true that you've been heard telling Chuck Norris that he is ugly and that his mother dresses him funny?
jannosmit Posted June 1, 2011 Posted June 1, 2011 (edited) i also broke an AC one, 2days later another dude comes to me asking if i have a spare valve, he also broke his AC valve. . . those ac valves are crap! Edited June 1, 2011 by JanMTB
Chubba Posted June 1, 2011 Author Posted June 1, 2011 Got a set of stans valves....one for the wheel, one for backup when the other valve snaps.
Bike Mob Posted June 1, 2011 Posted June 1, 2011 the ac valves are paper thin, you have to be really careful. The stans valves have lasted me years. Schwalbe also have decent looking valves now and I also have Campy tubeless valves. really good but short.
