Had a fair number of Raleigh 3 speeds over the years, but never a 5 speed Sprite. I've always liked the chainguard and am intrigued by (and a little skeptical of) Sheldon Brown's claim that the Sprite is a livelier alternative to the the Sports. Might like to try out this Sprite during the winter. Anyway, I'm curious if there's a consensus on the 5 speed drivetrain. Does it work well enough? Any chronic issues?
