Just got a Raleigh Grand Prix, $50, which here in NY is a great deal on a fine vintage ride. I got on the thing, and it rides like a dream--perfect size for me, too. It's dirty as hell and needs a serious cleaning/lubing, but it's in very good shape considering its neglect.

Seat tube has a label that reads, "Made under Gazelle, Holland." Anyone tell me where to find the serial #, and if so, what to look for? Would it be pure blasphemy to put on alloy rims and maybe a newer freewheel? I can't believe how nice the ride is, and for an all-steel bike, I'm also quite surprised at how relatively light it is. Anyone give me a little background? It has cottered cranks if that helps to date it at all,
