Retro Newbie
Have just purchased a 21" late 1970/80s frame as a single speed fixie, what would be the best size wheels 27" or 700c
 
what make is the frame? from that era it could have had either wheel size... 700c would give greater tyre clearance (esp. at the chainstays) and choice of tyres, but would also require a deeper drop brake caliper (approx 4mm more drop IIRC)
