Miyata 721a - more info requested!
Hello, this is my first post.
I have recently been given a Miyata 721a. It is in mint condition and looks very impressive, however I cannot find any information on the internet about the bike. Can anyone tell me about anything about it?
When I work out how to attach pics, I will post a few.
Cheers from Down Under (Australia),
Kristian

The 721 was an early 1990s model, but the only year where my literature references the A suffix is for 1990. The 1990 model 721A was a mid-range road/sport model costing $525 US (sorry no Austrtalian prices).
The frame is a bonded aluminum main triangle paired with CrMo stays and forks. Miyata did not spec the weight, but the comparable 718A from 1989 weighed 21.5 lbs, so yours should be close to that. The geometry is between competition and grand touring, but more towards the former. The group should be Shimano 500LX/EX with a triple crankset that makes it suitable for hilly terrain.
Despite the triple chainrings and rear rack mountings, it is not a grand touring model, as many people think. I've always considered this an excellent model for fast, hilly centuries or day rides. It's light, fast, quite reponsive and has the capability of carrying some rain gear, tools and a meal or two. It would also make a nice, fast, responsive commuter.

FWIW, I love the Exage 500 LX/EX/CX group. I've 'updated' my Miyata 512 with everything but the levers (the Exage Sport levers have a quick release and the 500EX don't). That wheelset in nice as well, and the HG-50 hub will take both Uniglide and Hyperglide cassettes.
