    F*#%*)$ Presta

    So I'm ready to put my new tire on my new wheel and of course Presta is the only stem that will fit through the wheel. I go and pick up 2 700 x 28-32 presta tubes and BOTH pop around 95 psi. Bontrager tubes. Am I missing something?

    You pinched the tube in between the tire bead and the wheel rim.

    I have done that about 6 or 7 times.

    Twice? I guess its possible, but I did semi inflate and had it in the wheel before getting the tire on the wheel. Sigh.

    Was the tire partially off the rim after the ruptures? If so, operator error.

    I used to do that all the time. Now, once I mount the tire and tube I'll put a little air then squeeze/pinch around the entire tire just to make sure nothing is still pinching. No problems since.

    I'm not sure what any of this has to do with Presta?

    Oh no, I had a blonde moment. It didn't register,for some reason, that there was no rim tape on the wheel. Where's the dunce hat. Okay now I have to by that tire jack lol.

    FTR, After I seat the tire, I place about 10-15 psi......I go around both sides of the tire with my thumbs and index finger.

    I pinch the sidewalls together and look beween the tire wall and rim to verfiy the tube is not pinched.

    If it is, this will more than likely allow it to pop into proper position.

    Be sure to push the valve back into the tire before inflating as it seems to be one of the probem spots since it's bulkier in that area.

    Talc in the tyre/on the tube is a good idea too. Lets the tube move a bit on inflation. Good bike mechs over here swear by it.

    You are working way too hard my friend. I just snap my fingers and my team mechanic and soigneur show up.

    While the mechanic puts fresh new tires on my bike, the soigneur serves me a nice, double espresso and maybe a small pain au chocolat.

    Then I get bike on the bike and I continue on my merry way.

    It is so sad when I finally wake up though.

    No mechanic...no soigneur, no pain au chocolat and alas, no double espresso.

    Popped one last night myself. I run them hard, so I'd just hit the desired 115 when it went boom! Wondered if it was error or a defective tube, but yes, the tire was partially off the rim.

    (When it rains it pours. I'd gone months without a flat and then had two in two days. First was a hole where the stem joins to the tube and the second was just a run of mill hole. Fortunately, neither flat manifested itself on the road. I always top off the tires the night before a ride, so I at least discovered them at the most convenient time and place.)

    ....I did forget to mention I am getting a back massage at the time. Most flats are Gina's.

    You know, I avoid what I can and she runs right thru.

    This thread is cursed. i read it thinking, "wow it has been a long time since my last flat"

    Ride home and

    that is about 2 cms in to the tyre. so that is what it takes to get though those tyres and a inner tough tyre liner

    It's good to know you figured it out on your own. I had the same thing happen when some of my rim tape slipped to the side.

    I've never heard of that before, but I'll have to remember that for future reference. I've had a couple of flats where they were caused by leaks around the valve stem.

    This is what I like about this place; I'm always learning something new.
