Trading Miyata 312 for Miyata 721

Wanted to get some opinions from you all. I have a 1988 Miyata 312 single speed conversion, condition-wise I would give it an 8/10. It has been fully rebuilt, etc. There is a seller on Craigslist that has a 1992 Miyata 721 for sale. I contacted him and he said he would consider straight trading the two. As long as his is in near the same condition, would that be a good trade? Also it is my understanding that the 721 is half aluminum and half chromo, is this true or does that only apply to the 721A?

Here is a CL link if his:

What is the goal of the trade? Are you trying to get back to a geared bike, or one that fits you better?

I've never seen a 721 before, but this old post reply from @T-Mar helps:

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.

Your 312 is a nice bike, something worth holding onto. But then again you mentioned a single-speed conversion, which detracts from the value somewhat.

FWIW The 721 is a bonded alu/steel bike, which some folks tend to stay away from.

Goal of the trade is to get back to a geared bike and have something capable of being a good commuter. The 721 would fit me as well because they are both the same size. I have all of the original parts for the 312 to convert it back into a geared bike, however it has no braze ons for racks.

The 1991 & 1992 721 used the same frame and almost a similar component mix to the 1990 721A. However, in 1993 it switched to RX100 and the catalogue states "full aluminum", though it looks like it still has the CrMo stays.

I have an excellent condition 721 I bought cheap on CL a few months ago. I watched it drop in price two times and bought it soon after the final price drop. It rides really nice and could be my primary bike if need be. I thought about giving it to my son in law but I'm a bit attached to it.
