Wow, this thread takes navel gazing to a whole new level.
Three things I look at with wheels; weight, colour and freewheel (7 or 8, 9, 10 speed), if all of those are right for the bike, on they go!
The C16R is a cracking bike that will easily take a wide variety of parts and still look good and ride well. Slap them wheels on, if they suit your build, keep them, if not, look for something else.
I agree with Neil, Age aint nothing but a number, for example i'm 43 and my wife is 31, ok a little off topic but I've done a few builds now and to be honest convention and period correctness is ones thing but functionality is another, some awesome builds grace the pages of this forum, and yes a catalogue perfect bike painstakingly restored does always look nice and is testament to the owner who has strived to get it that way, but a bike that has been built around the rider, the budget, and style of riding also can be equally as impressive.
See past the age................
