Well, I've gotten my first email from the Lake Pepin crew about the ride - gotta say that I'm a bit more than excited about this. One thing though - the Phillips I have and was going to take (as the Lenton could use some more work) has a head lug that isn't completely filled. It's the top tube lug, and it's enough to catch a fingernail on the back side of the head tube.
Now, it's been like this. Probably since it was built in '68. No wobbles, no jiggles, no loose feeling, and for all intents and purposes, it doesn't affect the bike at all. I've ridden it probably 500 miles by now, and haven't encountered any expansion.
Should I be concerned? I think I'm just being overly paranoid.
