    Whoops Pinched the tube

    HI,
    my new used bike had some nice mich slicks, and I was out ridding today really enjoying the ride, I was trying to avoid some of the heavy traffic, so I hopped on to the bike lane ( wide sidwalk ) and was doing fine not to many of those deep ridges in the sidewalk, and then I went crossed a road and saw a 1/4 in lip on the cement as i pulled up onto the next strech of trail, the front tire hopped it fine, but the rear seemed to bottom out the tire and POW, there goes the tube.
    I checked it after removing it from the wheel no visiable damge, tried to pump it up but it leaked pretty bad.
    Went to my LBS and he said it was a classic pinch flat..
    He asked me if the tires were under inflated,naw they were at their max pressure 110, but I guess my over inflated ass must have caused the problem, he thought that was pretty funny.
    He reccomended the bontrager race lite hard wall tire its pretty tough, so I bit and bought two with tubes and a spare tube.


    I also bought this neat little co2 bottle tire refil with a hand pump attached very thin and small
    It pretty neat.
    He said I won't pop those tires as easily, we shall see.

    pretty neat co2 or manual pump for air. It fits in a rack behind the water bottle the co2 bottle is stored in the seat bag.

    The racelite hardcase has been damn near indestructable for me, pray you never have to use the pump portion of that inflator though. It' s a lotta strokes to rideable pressure. The CO2 functions well and is easily throttled though. I give your purchases 2 thumbs up.

    Mich's are know to be very soft but grippy for racing. I tried them but too soft for my weight. Scared me while turning, gripped too much thought I was going over the bars. I like Conti's, a lil harder and max is 120 psi!

    Lov the tires

    HI,
    that extra stiffness really pays off 10x on rolling resistance, I was pleasently surprised by the easly they rolled, the other tire felt almost sticky and too soft almost like they were under inflated when they had 110 pounds in them.
    I think that maybe they were so flexiable if they took a hit they would swell abit all over to soften the bump but they could allow the hard rim to pinch the tube if the weight of the rider and the stiffness of the bump were great enough and in this case the 1/4 inch lip on the sidewalk took the tube out..
    If you weigh 148 pounds they may be perfect for you, but if you CD that weighs around 250 it may be a we bit over the limit for that model slick.
    Doug
