While you should avoid the use of levers for fitting a tyre when you can, sometimes you just have to. Use something with a thin enough tip to get under the bead, preferably not with a sharp edge! ~PB |

[punctures] Um, Am I missing Something ..?
... got my second puncture in as many weeks this morning. Set off on my
nine-mile commute and hit some broken glass at mile 3. 'Lucky' in that it didn't happen further on; 'unlucky' as it meant that my only choice was to walk home, drag the bike up five flights of stairs, and set off on the tube to work. Got back in this afternoon and decided to try pumping up the tyre before removing the tube, to see if I could localise the hole. Well it all became rather academic as the valve sheared right off. Ho hum. Anyway, I dig out a tube that's been lying in a drawer for a few months, and note with dismay that it's 700 * 28/38c whereas the one in the wheel is 700 * 35. Is that likely to be a problem? But the real question is: am I missing something concerning removal of a tube? I don't have tyre irons so use teaspoons. Could I get the small handle end of the spoons under the tyre rim? Could I ****. I eventually had no choice but to use a small, pointed knife to prise up the beading. Now this didn't bother me that much as the inner tube was destined for the bin anyway, but .. is it always that way when you have to change a puncture ? -- aigle_de_la_route Surly Long Haul Trucker http://2x2wheels.org/ |

I could rant .. ah hell, I _will_ rant ... I've had enough of cheap plastic. We have a chain of sportswear shops here in France (it's they who built the Surly and yes, further to my other thread about a loose headset, the front brake _still_ causes juddering, even 24 hours after it was tightened, and so it looks like they screwed up the build, and it was a 'moonlight' job, so no receipt to claim compensation, should I need a new Surly fork) called Go-Sport, and I bought a set of plastic trouser clips from them. They lasted all of three days. I was by no means brusque with them, but they'd just snap in my hands as I was putting them onto my trouser leg (I only wear the right-hand one). The last straw was about ten days ago, when I was stopped at a set of traffic lights on the way to work, left foot in the pedal and right foot on the ground. I lifted my right leg up as I pushed off, and the clip got caught in the pedal. 'Snap!!' Four bicycle clips in the space of ten days. I went and bought a set of velcro ones, but they don't look like they're going to last very long, either. What the hell happened to that word, 'quality' ? There's a set of metal ones available on the web, but the site is UK-based, and they don't ship to addresses outside Blighty. You do not need metal levers to fit tight tyres. You just need the right technique with thin-tipped levers - which can be made of average-strength plastic. Recommended: *Specialized Pry Babies*. Is that a great name or what? ~PB |

However, SM+ are one of the more difficult tyres to get on so I'd really recommend a set of tyre levers to go with them. Also, top tip, to avoid pinching the tube when wrestling the things onto the rim put 'em on first with no tube, then take off one side, insert tube and reseat. Not sure if it streches the bead a bit or what, but they seem to go on easier 2nd time around. And use the narrowest tube that you think would be ok. ~PB |

No, 35 is between 28 and 38 so no problemo. Inner tubes are elastic and fit a range of sizes. But the real question is: am I missing something concerning removal of a tube? I don't have tyre irons so use teaspoons. Could I get the small handle end of the spoons under the tyre rim? Make sure that the tyre is loose with the beads in the centre of the rim, then you will be able to get the spoon^H^H^H^H lever under the bead. is it always that way when you have to change a puncture ?

I've just destroyed four spoons ('destroyed' is a misnomer, as I can bend 'em back into shape), and there's a three or four inch section of the bead that will NOT go back onto the rim... As Phil said, the key is to get the bead into the centre of the rim where the diameter is smaller, giving you enough slack to get the last bit over the edge. What I do is to put the partly inflated tube in the tyre, put the valve in the hole and then one side of the bead into the rim. Centre the tyre and start to put the other bead on. when it gets tight I let more air out of the tube and start to haul at the bead from it's opposite side, trying to roll it over with my palms. I try to arrange things so that the last bit to go on is near the valve(since the valve will prevent the tyre from dropping into the well of the rim), I get the bead into the centre, where it's on and haul away. Mostly this works and after many years of cycling and a few of working in a bike workshop I think that I have only had to resort to using levers to get at tyre on half a dozen times. Of course when it's dark and wet..... Roger Thorpe |
