    Which is different from tubeless bicycle tire sealant. It performs a different job.

    I bought GP5000 before I knew about sealant or air compressors/tubeless pumps. They seated on my wheels with no problem using the pump in the usual manner. Negligible air loss overnight.

    It's always a good idea to bring a tube even though I usually don't. In about 12 years of riding tubeless road tires I've had two cuts in the tire (sidewall) that didn't seal or at least didn't hold enough air to get home, so I had to install a tube.

    IMHO, not carrying a tube is one of those things like not keeping an eye on the gas gauge in your car. The resultant situation is TOTALLY PREVENTABLE.

    Spare tubes when running tubeless road tires?

    I pulled a thorn out of my gravel tire in the garage. Sealant squirted out. Wouldn't seal. Tire pressure was about 50 psi. Garage temperature was about 45-50 degrees F. Using Orange Seal Endurance. Put some fresh sealant in and it sealed. Why wouldn't it seal? Temperature too low? There was plenty of sealant in the tire, as there was a sizable puddle of it on the floor.

    I've had good luck turning the wheel so the puncture is on the bottom while sloshing it around a little, others do the same while tapping the wheel on ground also.
    Either way, why tempt fate by not carrying a tube?

    Yeah, did that. Still didn't seal. The sealant must not work as well at lower temperatures, although I would think 50 degrees isn't that low. I always carry a tube. Also, I recommended never pulling out a thorn when out in the road, in case the sealant doesn't work.

    I've been using Orange Seal Endurance for years. I use it year round down into the 20's. Never had a hole not seal (never had it spray either).

    I agree, I wouldn't pull a thorn.

    The fact that it worked when you put new sealant in suggests that the existing sealant had separated, and so the thin liquid was what was coming out of the tire. If anything, sealant should work better in cold weather because it will get thicker with dropping temperature. Had the bike been sitting for a while, such that the tire wasn't spinning and therefore the sealant wasn't being sloshed and mixed?

    Yeah it was sitting. Just before a ride. Also, I'm not shaking the bottle enough before putting sealant in the tire. Thus, it's thinner than it should be.

    Sealant is a mixture of rubber particles suspended in liquid. If all your putting in your tire is the liquid it ain't gonna work.

    I gave the bottle a few shakes. The problem is if you shake the bottle too much, OS foams up and then how do you know how much you've poured out in a cup to inject or pour in the tire? I guess I'm going to have to figure out how much it weighs per fl. oz. and weigh it beforehand.

    Rubber particles? You sure? I know there's some glitter in there.

    You are overthinking it. Just shake it up and and pour a decent amount in there.

    2 things to do - use the dipstick to see how deep it is in your tire after the foam dissipates -

    Or you can do like I do and:
    1. Shake it up
    2. Put the filler tube cap and tube on the bottle
    3. Invert the bottle and squeeze the liquid off the bottom into another bottle.
    4. Move the filler cap to that bottle that won't have any foam in it, and put the desired quantity in your tire using the levels on that bottle to gauge it.

    I use the large 32 oz bottles, so that won't work for me.

    I use 32 oz and shake it up and then put it into a smaller 4oz bottle with the dispenser straw like I described. That cap fits on all their bottles.

    And here we have a perfect summary of why many of us old-timers don't think that tubeless is the solution to anything, let alone an improvement.

    Because it's too involved or complicated?

    I'm a new cyclist (10 years) but an older guy (50). I made the switch because of a trip to Utah and worry over goatheads. I've since decided to convert all of my bikes. Why? The ride is much better, and any apprehension over a flat has greatly reduced. Initial setup for one of the bikes was frustrating if I'm being honest, but I'm all in now.

    Not all old timers, I'm 63 and like tubeless - just sayin.

    Easier than changing a shifter cable for those still using them.

    I see it the other way around.

    I virtually never see posts from people with issues changing a regular clincher on a regular clincher rim. But valid or not I've seen hundreds of reports of people having some sort of issue or confusion changing out tubeless.

    I've only seen a tubless flat repair on the road twice both times when I stopped to help someone. Both times it looked like Ron Jeremy had recently made a movie using the guy and his bike and it was a freaking nightmare getting the tire off an back on with a tube in it.

    So from my angle if anything is going to cause apprehension it's tubeless. I know for a fact I can deal with clinchers with my eyes closed, so to speak. I haven't seen a lot to give me the same confidence about tubeless. I understand that goatheads might call for something I don't need but my take on tubeless is it's a case of a pound of prevention being worth an ounce of cure.

    You mean a Brifter cable, don't you?
