This is happening on the Homer. It has a large saddle bag but when I was riding yesterday, with maybe 5 or 7 pounds on the rear rack, it still had wobble going about 12mph. I did buy it used but it's the factory fork. I think it may also have something to do with the handlebars. They are

Dearest Friend, Is this happening on the used Homer you bought or the new-from-riv Appaloosa? I bought my Cheviot used on this list, and it got speed wobble at certain speeds down hills. Later, I got in an accident and bought a new fork from Rivendell, and the bike no longer wobbles. I

I'm not especially big (frames ~58 c-c), but 3 of my Rivendells have shimmied at 15-20 mph speeds and it was not due to headset wear. (I've never felt shimmy at any other orientation than straight ahead.) IME, shimmy comes and goes with very odd and very slight changes. None of these 3 Rivs
