puncture problems
I seem to be going through one of those periods of high puncture frequency.
So much for Kevlar lined tyres. Five times I have had to repair one in one week. Can't understand it as I try to cycle down either the left or right tyre track on the road. I have had a look at the rear tyre and it is full of perforations. I think I am going to have to get some new ones. Adam |

Since the punctures were in the area of that cut I can only reason that the kevlar fibres poked into or rubbed the tube causing a hole and premature deflation. Similar report from a cycling buddy as well. To fix we both upgraded to a Schwalbe Marathon Plus. Next time I buy a tyre it'll be another SMP or a standard, none kevlar belted, tyre. -- del 8-) I've had puncture problems every week on the MTB and asked my local shop about kevlar liners made by Panaracer. Their opinion is that kevlar causes more punctures than it stops. So I'm trying out gunk filled tubes on the MTB. For the road bike I've not had a single puncture yet using Continental Gatorskins.

puncture problems
For the road bike I've not had a single %^&*(!@} yet using Continental
Gatorskins. I've had a few with the gatorskins, but they've also been decent sized bits of glass - the kevlar band isn't impenetrable. I did pick 28 pieces of glass last time I checked the tyre, so it seems like the kevlar does it's job. I'll be trying out the GP4000s next - they use vectran and promise similar puncture protection without such a big weight penalty. |

The additional weight might be an issue for some people, but it doesn't really bother me. |
