Found the problem

The front wheel of my LHT was built up with a Dyno hub by Peter White. I have the stock front wheel hanging in my parts department. There was some type of rim tap installed (not sure if it was I who put it on or PWC) but it was pretty thin in a few spots. The ridges of the spoke holes were sticking through in a few locations. I was able to determine exactly which spoke hole was causing the problem (props for matching up the logo on the tire with the valve hole and careful removal of the tire and tube while changing flats) and installed a new rim tape from MEC. I combed over the rest of the rim and the inside of the tire just to be sure, and they looked fine. We’ll give her a week or two to see, but I’m pretty sure that this little problem should be gone now.
On the fixie, I found that I had a failed presta valve. No tears in the rubber or anything, just the air leaked through the valve itself until it was down around 15PSI. I know you can tighten up the little valve inside the stem on a Schrader valve, but I don’t think this is the case with a presta. New tube on there and we’ve got both bikes back on the road again. Thank goodness!
