technical question for bikers

Skybird · 10-24-09, 08:13 AM

Any input is welcomed. I googles a bit in the past minutes and found MANY complaints about the Presta Valves. And these were complaints not owing to the valves being called "French". It seems they are pretty much hated outside the racing bike community.

I thought about getting tubes with Schrader valves, but it seems these are low pressure only, up to 4 bar at max.

I could be wrong - but I think Skybird is talking about what we call a bicycle. Not a motorcycle.

Sky, here a "bike" is first thought of as the motorized kind.

Most motorcycle tires don't have tubes.

I ride a bike (or used to, don't have one anymore) but again, it was motorized so I can't really provide any input.

Yes, a bicycle I mean, like "bike" in "mountainbike"

. Tricky language. Mine is a "touring-bicycle-bike".

I actually like them, though on my new bike (-cycle) I have Dunlop valves. On my old one I've never had any breakdown, and my impression is that they're a bit tighter because you have to screw them twice (valve + cap). Maybe that's the reason why they're so widespread since I don't think that you can reach pressures over 6 bar with a regular bycicle pump.

Can't really give any advice. Usually the more fancy the bicycle is the more fragile it is, or requires specialist knowledge. My advice is: take it to a good tour bike repairer and ask advice.

On a sidenote, I hate people who break bottles on the streets during weekends etc. Had to change a tire on my bicycle because of some idiot.

I hate people who break beer bottles on my head more, but those who use streets are bastards as well.
