Fixing Punctures / Puncture Repair / Exploding Tubes

You're not doing it right.

You shouldn't be using levers, seat one side of the tyre first then put in the tube and then do the second side, being careful not to pinch tube under tyre bead.

Thanks for moving to a more appropriate area. Much appreciated.

Seems a bitch with these rims though. The first I've ever had this problem, having generally followed the above tyre changing technique on countless occassions.

Perhaps the tyre wall/bead has weakened. How could i tell this? Is there such a thing?

Also, put some air in the tube before you put the tube in. Not too much or the tyre will be hard to get on, but just enough to give it a round shape so it tends to expand out into the tyre and not fold up and get stuck between the tyre and rim.

Thanks.

Should point out that this happens mid ride, after I've put the wheel back on and ridden for a few miles with no signs of the tube bulging out.

This isn't a puncture issue, although thats the inevitable result. The flat is fixed, new tube fitted correctly and away you go, but in this case just a few miles.

Fuck it. New tyres it is.

this^^^ also "massage" the tyre into the rim, kneading it back and forth. Inflate a bit more and do it again. This should help the tyre seat properly and ensure the tube isn't caught. pump up to half pressure and give quick check over, then pump it up to desired pressure.

SRSLY?
3 pinch flats on the rear tire? I only mis-jumped the motherfucking kerb once.

i had the same 2 days ago rhowe ! i was this close to giving the whole cycling malarkey up, it was that bad. 3 holes never made so miserable ever

I had my first "Park patches are shit" day yesterday. Helped along thanks to London's Wet & Glassy East London.

Your not supposed to use them. They are lucky charms to appese the cycling gods. I cant imagine them actually be usable on a raining commute.

I think I've used them three times without further fail, over a couple of years. Might've been cack-handed mending TBH.

Guys i just found out that you can cut up thin butul tubes and use them as patches.
The Maxxis Flyweights are perfect for this because they are thin, and saves ever running out of patches. Thicker tubes don't work.
Cut a piece that covers the hole, rough both tube and patch with sandpaper, apply glue, wait 5 mins, apply patch, done! Awesome.

or... you can cut down those large patches you get in the box that no-one ever uses, into small 0.75/0.50cm ones, they work good too.

Top tips chaps

No, Tip Top.

yea, i ran out of patches the other day, and had to do exactly that, those patches are completely useless unless you cut them down anyway, for 23c tubes.

besides how many patches can i get out a a cut up tube? say 200 ? I thought it was a well good shout to save money.

You're not doing it right.

You shouldn't be using levers,...

Unless you're in a situation where you have to combine new tyres with deep rims, in which case you may have no choice. I had to do this on Saturday, in the dark and the rain, after riding a 200k. It wasn't fun.

Out of interest, has anyone come across using milk to prevent slow punctures?

My girlfriends dad ended up with some tubs that you can't actually repair so apparently uses the old trick of putting some milk in them. It's utterly rancid when he asks me to pump them up.

If you're referring to the pre-glued patches then I'm not surprised. They're only good up to about 50psi.

sounds plauible, the coagulated milk blocking the hole.

you could use stans tubeless gunk in them

also on MTBR they have various recipes for DIY ghetto tubeless sealant

Get different ones - I have run them at over 100psi without problems.

I've long since returned to switching out inners and using unglued patches later on as this always works for me.

I'd probably just ask my girlfriends dad. He's been riding and racing cyclocross since before I was born. I think he knows his stuff.

Do that when I get home. Better on a group ride to do a quick repair and get going without taking wheels out etc.
