Just got back from doing blencathra and skiddaw.Had a good time apart from front wheel puctures (three in total).All were when I was going downhill and braking.Had a couple of hairy moments stopping but by more good luck than management I managed to stop on :lol:.On taking the tyre off I discovered that I hadn't had a pucture as such,more that the valve had ripped clean from the inner tube 8O.Never had this happen to me before and to have it three times in one ride seems very unusual.Any idea why ?.

I've had it happen to, guessing the tyre is sliding slighlty on the rim and pulling the tube round?

Yes thats what I was thinking.It just seemed strange to get three in one ride.It must be my fantastic good luck :roll:.

What pump do you use? Could be pulling the valve around as you inflate.

Or just some talc in the tire to lower the friction between tire and tube. It used to happen to a friend all the time. He was a serial tire-changer but a little talc a couple of years ago put paid to it completely.

It is an odd phenomenon. Happened to our group about 5 times in one morning in the Pyrenees. Used all our spare tubes up and had to walk the last bit down. Tried in vain to patch/glue it. Stocked up on tubes at lunch and it never happened again that weekend.
Lots of possible fixes, some suggest talc on the tube so the tyre can rotate without taking the tube with it. A friend puts a couple of dots of superglue on the bead only on one side. You could roughen the tyre/rim interface. I've not had it happen since I switched from skinwall tyres but I run fairly high pressures.

Thanks for the replies,will try the talc suggestion for next time.

More pressure and talc.
I have fouund schwalbe tubes to be more reliable than others. You can also go for the ultralight ones, remove the valve and add a little sealant, I go about 50ml per tube. This sorts out minor thorn punctures.Posted 1 year ago # -

Going off my pit bitching yesterday I'd say balls to that.
Talc and pressure or better tubes if you bought cheap ones.

Having too small an inner tube causes this as well. My mate took his brand new Trek (can't recall the model)he bought for the Alps, and had a succession of punctures just riding the Chilterns. It had been fitted with 1.75/1.95 tubes the tyres were 2.35s.
