my first post (great forum!)... im UK based
I've recently bought a 1985 Miyata One Thousand touring bike in mint condition ....
I ride Audax but want to do some touring (wild camping/fishing) and my 1st trip planed is a 650km fishing/camping trip along the south coast of Ireland
I'm 5'7 and looked carefully at the geometry and the most important critera was the top tube length ... My other bike is a Trek Emonda Sl6 with Dura Ace Di2 and that is a 52cm ....
top tube length of the Miyata in 50cm is alsmost identical to the 52cm Trek
bought the Miyata and I went for a bike fit from a local LBS who was recomended by several cyclists in my area
the price was not cheap (£200) and what I can say is that before I had the bike fit, I set the bike to what I felt was correct ....
after the bike fit, things were set up a lot differently .... hard to explain the difference, but the easiest way to describe it is that before the bike fit, I was sitting 'ontop' of the bike, where as now I'm sitting 'inside' the bike (if that makes sense)
the fit that I had took over 2 1/2 hours, was amazing as it was in 3D and the computer automatically gave all the angles and highlighted the problems in red (amazing software) ... cleats were also properly set, I needed insoles in my shoes, arse measurements were taken to ensure that the saddle is suitable, handlebar width was checked etc etc
the fit I had was with software called STT 3DMA

get a bike that has the correct top tube length..... go for a proper computerized 3D bike fit .... you amy need to change the stem length, handlebars, saddle etc, but you will have a bike that fits proper, and which is comfortable for long distances
