I've been using a Quintana Roo Kilo with pretty low end components (Tiagra) and although I had it fitted, I am aware that it is not optimal for me simply because the frame size wasn't ideal for me.
I'm considering buying a used Kestrel KM40 (2000 model with Dura Ace components that are a couple of years newer. The owner has put about 1,000-1,500 miles a year on it. It is 52 cm and I am about 5'8" - 5'9", the same as the seller.
I've got a limited budget so I want to get the most bang for my buck. Would this be a worthwhile upgrade? I'm concerned that it is a 2000 model and wonder if technology has changed a lot or wear is a factor. Same for the components. Finally, it was 650 wheels which I was told are falling out of favor. Is that a big deal? Any thoughts would be appreciated
