Bent fork. This fork has bent at the thinnest part of the crown on both legs. The fork legs should be in-line with the head tube.
Symptoms of a bent fork are (1) heel striking the ground more frequently in corners, (2) front wheel mud-flap dragging more frequently over debris and bumps, and (3) an increasing reluctance for the bike to corner predictably at greater lean angles.
If your fork looks like this, it is bent and should be replaced.

Valve separating from tube, but there is no leaking. This was a strange tube. It went flat on me while I was descending Page Mill Rd. There was no noise, just a softening tire, then flat, probably over a few minutes.
When I re-inflated the tube it held air. I have this tube hanging in my garage, inflated and bulging, for several days now with no apparent loss of air.
I'm suspicious that this gap at the valve leaks intermittently. I've tried wiggling the valve stem, but this doesn't cause any leaking. The only thing I can't easily simulate in the shop is to apply heat as if it were on a wheel with a hot rim. (When the tire went flat on the Page Mill descent I singed my fingertips and had to wait several minutes before I could touch the rim.

Soubitez front fork generator light The front lens of this fell out while I was riding home from work one evening. Before I could retrieve the lens, a car ran over it and crushed it into a hundred pieces. I got many years of use out of it, but it had high rolling resistance.

Ritchey Comp Pro rim, worn to a half millimeter thickness I got about 23k miles on this rim before removing it from service. Most of this wear occurred on about three or four rides ridden in the rain that included some long descents that required continuous or near-continuous braking.

Ritchey fork break. "Fork had been creaking for some time, then suddenly felt really loose when climbing out of the saddle." Fortunately, no crash. Boris tells me the fork was new in 1987 (30 years old) and the bike has at least 12000 miles. Photo courtesy of Boris Foelsch.
