    Hey are these made at all? It's a pain pumping air on my wheels with deep aero profile and using the regular valve slime tubes.

    I'm not exactly sure how much they weigh - I'm using the Specialized Airlock Roadtube.

    Yeah it's extra weight but consider 2 things:

    1) I haven't had a flat in over a year and a half
    2) I lost more than 10lbs to make up for the extra rolling weight which is more than enough.

    haha

    Where can I find some online? I've only been able to find tubular presta valve extensions.

    I've tried shraeder- presta extensions without succeeding in getting the slime in the tube.

    Are you talking about something else?

    Valve extender like:

    <http://www.excelsports.com/new.asp?...ender+Presta&vendorCode=CAMP&major=1&minor=31>

    or buy the Continental tube with long valve stem and remove the Presta part to infuse the slime, and then return the valve later:

    <http://www.excelsports.com/new.asp?page=8&description=Tube&vendorCode=CONTI&major=1&minor=31>

    48 or 60 mm in length depending on how deep your rim is.

    I have some 48 mm that I bought for a project if you want to experiment let me know. I will contribute one to your cause, but not the Slime.

    Anyone else bothered by how that crap smells? Why on earth does the stuff need to smell like dead squid?

    Looks like there was a thread on Slime with Presta valves in March over at Bikeforums. Reports are Slime doesn't hold above 65 psi and the Presta valves clog if Slime is poored through them.

    So the Slime idea is probably not going anywhere, but I'd like to try since I've had so many pinch flat rears on a heavily rear weight biased recumbent. I normally run 80-100 psi on that tire, but at 60 psi I could still keep riding.

    So how does one remove and replace a presta valve?

    How does one remove a Presta valve.

    Most Presta valves are not made to be removed. However, most Continental Presta valves can be screwed out.
