I don't know what a Puch Cavalier is tbh so this may be irrelevant but make sure buying wheels, you get the right spacing.
Track wheels i.e. flip flop and ss etc are 120 spaced and geared road frames will take a 130. a 120 wheel might not have long enough axles to be able to fit. So a cassette wheel with ss conversion might be the way.
Definitely second hand through here all the way.
My mate built up "the fanelli" for under 200 quid all in and all from lfgss classifieds parts. Search it on here if you're interested.
