I removed and replaced the cassette on my bike (making no changes). Now I find that when the wheel is under load the chain climbs up on the teeth of the smallest sprocket (see photo).
Everything works fine with the other gears or when the wheel spins freely. This seems to be the *opposite* effect I'd expect if the chain had stretched or the gear teeth were worn. Instead, the pitch of the chain seems too short, not too long. Can anyone explain what's happening and how I can fix it?
