    which green slime to use for "small" flats

    I'm a bicycle newbie. I have been doing daily light riding (commuting) to the train station for a little over a year.
    I only had one flat so far. It was bad enough that after filling the air in the tire, it all went away after a few hours.
    I recently had a very "small" flat. When I fill the air in, in can pretty much hold for 1-2 days for 3-4 rides of about 5 miles overall.
    This time, instead of replacing the tire, I would like to try the green slime solution. I've been reading mixed reviews on it but I'd like to try it.
    I went to amazon.com and there are a bunch of different ones (different number/series). I was wondering which one should I get?
    If it matters, I have a Specialized Sirrus bicycle. The tires spec is "Specialized Nimbus w/ Flak Jacket, 26TPI, 700x32c".

    Thanks.

    I have no experience with slime, but I've had good luck with Vittoria Pit Stop fixing slow leaks like you describe.

    I'd put a new tube in, and find the slow leak in your spare time..
    pump it up, put it underwater, and look for bubbles..

    NB: feel around the inside of the tire for stuff that will keep making new leaks,

    little pieces of wire , etc.

    I thought about that. The problem is I have a recycling plant on my way and there are always glasses and stuff on the road (I can't avoid it all the time). Even without this flat, seems I always loose a wee bit air every weeks and was hoping that the green slime can help with that.

    more info.

    "Small" flat? Isn't that like being "slightly" pregnant?

    Surely a puncture = a puncture and therefore has to be fixed no matter whether fast or slow. In my case, replace tube, and then patch (usually as part of a batch - see threads passim, later). The reference to losing pressure over a few weeks might be explained by the natural tendency of nitrogen to migrate through butyl rubber thus reducing pressure over time.

    I think he means small puncture, like a pin prick as appose to a gaping wound

    Bicycle tires will typically lose a bit of air over time, how much depends on the quality of the tube. I use Schwalbe tubes in my daily rider and can get away with only having to add air once every couple of weeks. I have an old cruiser that we keep here on the farm, it has WM Bell branded tubes in it, it needs air added at least once a week. When you replace a tube that has a pinhole leak (or larger) run a cotton ball around the inside of the tire first and see if it catches on anything. My curse has been the little pieces of wire from blown out truck tires, hard to see and hell on the fingers if you find one with your finger tip.

    I don't like the slime, I had a blow out on a tire with a slime tube (came on the bike new) and it was a helluva mess to clean up. YMMV

    I ended up using this: http://www.amazon.com/gp/product/B00...=ATVPDKIKX0DER

    Worked like a charm. To my surprise, after I filled the tire with air I filled it in the other tire and discovered that one has gone flat as well over the last two days. So I filled it up there as well. It has been a few days and my bicycle tires are holding up just fine.

    I have a bicycle shop around the corner from where I live but they are closed until March and the closest bicycle shop is far away so that was my main reason of using the slime rather than replace the tire.
    But I think it is good. For whatever reason, there are lots glass pieces in a certain spot I ride and that spot is hard to circumvant.

    I never learned to ride a bike. It is my deepest shame.

    I used to use Slime brand slime, and it stopped me from getting flats until it clogged up the innards of the valve and the tube could no longer hold any air.

    My vote is for:

    1. Carry a spare tube and a pump and a patch kit... use your spare tube when you get a flat (making sure that whatever caused the flat is removed as fietsbob suggests)
    2. Patch your punctured tube when you get home
    3. Buy flat resistant tires

    I also used Slime brand slime. Yes, I've had issues with it clogging up the valve, but I just pulled the valve core out and cleaned it and it was fine.

    I use it on my commuter, and it got me to where I was going (on time) a couple of times. I'm not using it on my long distance bike though, because cleanup is a pain and I would assume trying to patch in the field would be really bad too. But then again, if the slime doesn't work it probably just needs tossed anyway.
