[RBW] Re: Flat Tire Help
On my Atlantis, the original front flatted with unusual frequency. The punctures were consistenty on the inside of the tube. Replacing the rim strip took care of the problem. In your situation where the problem is in the stem area, you might try a rubber washer in the stem hole. The Mavic rims I now have on the Atlantis came with rubber washers. dougP On Dec 14, 7:05 pm, John wrote: > I've run into an unusual flat tire problem on my Ramboo.

Re: [RBW] Re: Flat Tire Help
Several years ago, I was using a traditional brass Silca presta pump head (of the sort that you can buy from Harris Cyclery). It is a great pump head, but it has no locking mechanism, so it is full on secure with no release. In fact, it locked so tightly on to the threaded Presta valves that I often suffered flats at the seam where the valve joins the tube. Not necessarily at the time of inflation. I switched pump heads to a less "tight" fit - including ones with a lever. (Serfas, SKS, etc.) and the flat problem went away. When you pump up, is there a lot of friction to remove the pump head?

[RBW] Re: Flat Tire Help
I had a string of tubes failing at the valve stem. I think it was caused by the tube creeping when the tire pressure was too low. Sometimes it was a hole, sometimes it was more like the valve attachem started peeling up. Hard to patch a tube that close to the valve stem. Do you see your valve stems cocked over at an angle? That's what I was seeing on my mountain bike. I started being more careful about proper inflation, and started using the dork nuts instead of keeping them for M6 spacers. I haven't had that problem since. Philip Philip Williamson www.biketinker.com On Dec 15, 5:25 am, Michael Hechmer wrote: > Yikes, front tire flats are scary; I hope these were slow leaks.

[RBW] Re: Flat Tire Help
Yikes, front tire flats are scary; I hope these were slow leaks. Is the stem breaking away from the tube? Are you using tubes with threaded stems and a locknut? I know a lot of mechanics throw away that locknut, claiming its superfluous, but I believe it helps to keep the tube in position, at least during installation. Do you have, or can you borrow a different front wheel and test your rim hypothesis? michael -- You received this message because you are subscribed to the Google Groups "RBW Owners Bunch" group.
