Bike Fit--Miyata 710
I have a question about bike fit. I've done a lot of internet reading, and I guess there are so many factors that it all comes down to a matter of preference, but I thought I'd post to see if I could get some input.
I am a little over 5'10" and I have a long torso and long arms but short legs. For example, I wear a 40L suit jacket, yet I wear pants with a 32" inseam.
I have a 57cm Shwinn LeTour Luxe and a 62cm Miyata 710 (although the standover is noticeably less than an old 25" Schwinn I once had). The Schwinn is probably a better fit, but the Miyata is a better bike. So my basic question is, can I make the necessary adjustments to the Miyata to make it fit, or am I better off just riding the Schwinn?
I've been riding the Miyata as my commuter for about 2 weeks. When I have the seat adjusted to the proper height, I noted a couple of things: (1) the saddle is lower in relation to the frame, and because it is a large frame, the handlebar drops are correspondingly higher--I'd rather have a more agressive posture; and (2) when the pedals are in the "neutral knee" position--with both cranks paralell to the ground--I estimate that my front knee is about an inch behind the pedal spindle (as noted here: https://www.coloradocyclist.com/bikefit/).
Should I try lowering the handlebars and how would I do that? Should I move the seat forward a bit?
Anyone want to trade a smaller Miyata 710 for a larger one?

I am no pro on fit but I am 5'10" as well and I ride a 54 cm bike more comfortable than a 56cm. I just bought a classic steel bike but never measured it I just test rode it then bought it. but My standover on it is decent so its probably a 21" frame. I would suggest trying to get a smaller frame but its just My Opinion.

I am 5'10" with a 31.5 in inseam and I ride a 54cm 1980 Miyata 710.
62cm seems like it would be way too big, do you feel stretched to reach the bars? As cool as the 710 is, I couldn't see myself riding something that doesn't fit.

Well, my true inseam is probably more like 33, considering I am okay with the standover--I can straddle the top tube flat-footed, its just snug.
I rode the LeTour in this morning, and I noticed that even on that bike, with a 5cm shorter seat tube, my knee is not directly over the spindle in "neutral" position, its still about an inch back. Maybe I just have short femurs/upper legs? Or the seat up too high? Its set so I have a slight bend in my knee at the bottom of the crank.
In any event, my arms had a more appropriate 70-degree bend.
With long arms and torso, I can't see myself shopping for a 21"/53cm bike. I fixed one up for a friend and its too snug in the arms.

The KOPS difference may be due to the fore-aft saddle adjustment
FWIW I run a 120mm stem, giving 21" from center of handlebar to front of saddle, the way I set it

PTB,
While "Mimi" (my '68 Peugeot U08) has been at the cosmotoligist this summer, I have slept around with a bunch of different bikes. I have come to the conclusion that I like tall ones, skinny ones, short ones, lanky ones, chubby ones. I'm not very discriminating now that I'm well into middle age! Once I'm in the saddle and comfortable there with my leg adjustment, I quickly get used to the bike.
All this, of couse, is within some reasonable range, but what I'm trying to say is that I have re-evaluated the importance of finding the "perfect" fit. Like women, if the fit is reasonably close and you like her, your relationship with the bike should, if not "blossom," at least be workable.
Also like women, you don't have to read a book or check with your peer group. If it feels right to you, go with it! A 62cm classic frame would seem to be to tall for you, but what do others know?!
Enjoy.

This might solve all my problems:
https://cgi.ebay.com/ws/eBayISAPI.dll...MEWA%3AIT&rd=1
Anyone know if it is a step down to put the 710 componentry on the 210 frame? Also, note the auction says the 210 has cantilever bosses--I have some spare canti parts around from a mountain bike that I disassembled, but would rather keep the dia-compe parts from the 710.

Death fork? Naaaah!!
The 210 was Miyata's lower-end touring bike. While below the 610 and 1000, it's still a damn nice bike, and the equivalant of a 310/312 in road bikes. It will have touring geometry and canti bosses.

Put some lights on!
My current thinking is to ride the biggest frame I can stand over. I'm 5'-11" and I'm happier on my 58 than my 57 (both Japanese) and I'm currently building up a 60cm track bike (Italian).

So the order of Miyata's touring bikes, in descending sequence, would be 1000, 610, 210? What would be the series of their road bikes? I've heard of Team Miyata, Pro Miyata, 710, 510, 310, if my memory serves me well.
