I added cable guides, downtube shifter bosses, and water bottle mounts to my paramount years ago. Of course the pump boss sticking out from the head tube is worthless now, eh? Glad I did not put on cantilever brake mounts - Because my centerpulls do have enough room to adjust for 700c if need be.

Guess what I am saying is - not knowing what the future will bring - had I done the cantilever bosses - may have had to get them moved later and the frame repainted (which we will probably do with the tandem but it needs new pain anyway.

Probably ruins a bike for collectability but is functionally nicer. It is, after just a bicycle. It can either hang on display or you can ride it until it dies a noble death.

Oh bikingshearer - I had my post up while you posted - agreed! So don't go laughing at my lavender paramount with pink toe clip straps and brake cables!
