What are the advantages of the various puncture preventative measures?
Cycle Tyre Seal: This is a very handy 'Get you home' repair. You just squeeze the product into the valve and it re-inflates the tyre and mends it at the same time. However it will only last for a fairly short time and you will need to replace the inner tube at home.
Dr Sludge: This is generally put in before you have a puncture and sits in the inner tube and is forgotten. It works without you even being aware that it is working. The disadvantage is that quite a number of 'Presta' valves do not have removeable cores and therefore cannot be used. In this case you need to buy a ready filled Dr Sludge inner tube which are also available. The disadvantage is that they do add a small amount of weight which might effect some racing bikes.
Sureride Tapes: These give good protection but the tyres must be kept fully inflated. Otherwise they will slip and can cause you punctures. Again the racing fraternity might notice the weight.
