Ksyriums...tubes?(12 posts)

Ksyriums...tubes?Tony The Tiger
Jan 20, 2002 5:08 AM
Normal length valves (36mm I think) for tubes don't seem to fit my new (used) ksyriums. The 60mm valve length seems meant for a much taller rim, and stick waaayyy out. Is there some in between size than is good for Ksyriums? Where to buy? Thanks!

Where do you get them? My LBS doesn't carry them, and I can't seem to find them online!

I've used Ksyriums over 2 years with nothing but standard tubes. When first inflating, push the valve out a little by pushing against the tire a little. After you get some air in the tube, the pressure will force it out sufficiently. I have never had a problem with them this way.

that comes with the tube, you don't have to push anything out. I learned this after struggling with the fashionable but questionable "nut-off" configuration for awhile, and my brother, who could give a sh*ite about weight, anyway, just said, you have got to be kidding me that thing weighs less than the graham cracker crumbs sticking to your chin put it back on and use it as God intended.
After that, regular tubeshave worked just fine. If you're really that concerned about rim weight, just use the nut on one wheel; at least you'll have it when you need one.

You can throw one in the saddlebag once you're done inflating-- no worries about increased rotating weight. I do have to add that I didn't want to tighten the valve nut all the way down to the rim because of some inexplicable fear of scratching my wheels with it. (They're still new; I probably won't care after a few miles.)

They can also come loose and rattle during your ride!
good point, but I don't need itDog

I've never needed them. I'm only talking about pushing the tire/tube against the rim for about 2 seconds only when the tube is completely flat. On re-inflation from ride to ride, it's not necessary.

It's not all a weight weenie thing, it's just that I've never found the nuts to be necessary, at least on road bikes. It just lengthens the time for tube changes.

Hey, they're just not needed - and when changing flats it's just another detail to mess with and it takes time. Simplify, simplify, simplify. Isn't life complicated enough?

BTW - it's a lot more than 2 or 3 seconds - go time yourself Mr. Stopwatch.
