I'm thinking about buying a racer, but I remember from the last time I had one, that every time I went out on it I got a puncture. Is there a solution to this, I seem to remember a liquid that went into the tyres on a mountain bike, but does this work on a racer?
Not sure how successfull they were or if they are still around but a few years back you could get special no puncture tyres. They were more like a honeycoombe hose rather than using air so they never actuall got punctures.
The honeycomb tyre idea is and was a brave but futile venture; road resistance is atrocious. What you want and works well with any wheel is 'Goop' available under different brand names for about �7 for two tyres, then you will rarely get a puncture. I have Goop in and mend about once a year, [daily riding] but when you do mend there's about 20 punctures, so trash it all and get new innertubes and new Goop. Works fine for racers :-) best thing yet.. Suretrack Schmuretrack.
About 35 years ago I used to buy things called Tyresavers which were, basically, pieces of springy wire fixed to the same bolt as the brakes and bent round to rest on the tyre tread. Apart from the really big stuff (broken bottles etc.) most things don't puncture the tyre until the second or third revolution and this bit of wire flicked out the offending article before it had gone round once. I used to ride along a canal tow-path quite a lot and don't remember getting a single puncture after fitting these.
