Fixing a puncture on the fixed

[palinurus]

Right, I've had no punctures (yeah, I wrote the whole thing...) for ages. Not on my commute or training bike anyway. Haven't had to fix one at the side of the road since Oct 2005. Really. (Armadillos, 25 and 28 mm).

I've had a fair few on the 'cross bike (fair enough, lightweight tyres, low pressure, treads fulla mud) and one on the TT bike in that time.

This last two weeks I've had three. Three!. Different causes (staple, bit of flint, bit of glass).

It was only today that I realised I could get the rear wheel out without undoing the mudguard stays and the rack.

Damn!

Dont you have room to just roll the tyre off the side of the rim? I dont have a rack etc, so dont know how much room they provide, but I never take the rear wheel of my fixed to fix a puncture by the roadside.

 

[palinurus]

Never thought of doing it that way, maybe I'll try it. In this case I wasn't so much fixing a puncture as changing a tube so I needed to get the wheel out for that.

The rear mudguard on my Pearson, fitted with track ends, is set just far enough away from the wheel to allow me to just slide the wheel out. I've also got secu clips on the back as well as on the front, if I need to I can just pull the stays out

You need to fit the quick release clips that are often on the front guards. When I specc'ed my fixed I was about to 'ask for them' when the LBS said he fitted them as standard. Quick tug, guard is out of the way. SKS guards front and back with the quick release clips on = as good as it gets with a fixed........

Doh.... dave r got there 75 seconds earlier......

Cut old tube with scissors, remove.
Cut new tube with scissors, place on rim and repair with patches.
Simple

Not quite as extreme, but I was thinking about the possibility of having an inner tube that isn't a complete loop.

For high pressure the two "ends" should push together.

What do you think?

I know that the innertubes on the Paris Velib bikes are like sausages, pop the tyre off on one side, push in and inflate. I don't know whether there are any issues associated with this system for high pressure road bike type use.

I have to undo 2 rear mudguard bolts to slide the wheel out too. I've never thought it that much of a problem to be honest. I just have to remembered to put them loosely back in again whilst I change the tube, for 2 reasons; to stop the mudguard flapping around and breaking and, so I don't loose the buggers!

I have got one of those tubes in the rear of my old mountain bike. Like a long sausage that overlaps by about 6 inches and holds 60 psi no problem.

I have had it quite a few years and remember buying it at halfrauds but not seen any like it for quite a time

Puncture problem eh? I still see that no-one has followed the advice I gave a couple of weeks ago about fitting two tyres to the rim? On the Langster I have a 23mm slick, over that a 1.25 Marathon and have filled the gaps with magic foam.

Punctures now are a thing of the past.

As is road feel and accelleration

I use Marathon Plus, so don't get punctures. But I also use RaceBlades, which take less than a second to remove and replace. Actually, I don't have to remove them to get the rear wheel out. It takes longer to unscrew the adjuster barrel for the S3X.

On you silly, silly person. Snubbing your nose at Madame la Crevaison... that's just asking for it

I remember reading somewhere, probably here, that Robert Millar would train in the winter with a tubular tyre inside a regular tyre.
