Thank you very much for your helpful reply - I have read the other posts (will probably read again later as some of that is quite complicated, but I get the main points..). Yes, I am sure your bike #2 is the Paris 50 we are looking at. In fact we might go and look at this again and see if we can adjust the saddle position at all, as theoretically the size should be in the right ball park. Also we can try a shorter stem as this bike was already made up and had a 120mm stem. Last time we were pushed for time, I thik we need more time and a test ride if they will allow....... I think the bike #4 is too small as its smaller than her current bike, though I know the different geometry could affect things. And I think unfortunately that the beautiful 2013 easyfit 51 they have will be too big (the 49 probably would have been just right but not available....). Initially we were thinking that it might not be too big as she does ride the Roubaix with a top tube that is just 8mm shorter, but the roubaix has a 90mm stem and I am sure this would be the shortest feasible on a Paris. The Roubaix has not been set up for her but she does feel some pressure on her wrists and forearms which may suggest its slightly long? But her back is much better on this bike than on hers and this is the main issue we want to resovle (as well as getting a better bike)......My husband is only slightly taller than her, his legs are the same length but his torso longer and shoulders broader. I dont think her arms are particularly short or long, her arm span is exactly the same as her height, but obviously her shoulders are narrower than most men.
How do you find the Quattro? We would have considered this, but the only one they have is definitely too small.....I dont think there have been any major changes in the frame since 2012 (except now its think2 but there are not any 2014 ones here anyway....) so it shouldnt matter that we are looking at a 2012 model?
Once again many thanks for your help.....
