Jun 3, 2016 at 23:58 comment added FreeMan I can understand that it may not be for everyone. I did want to put it out as a possibility. I can fully agree to disagree with you on stem length, as it worked quite well for me for many years.
Jun 3, 2016 at 21:33 comment added Criggie @freeman interesting advice - personally I don't like a long stem. So the only advice that we all offer in common is "try the bikes out"
Jun 3, 2016 at 15:10 comment added FreeMan I would agree with @Criggie - go for the smaller frame. If you decide later that you want a more aggressive/aerodynamic position, you can get a longer stem to effectively lengthen the top tube, and you can get a longer seat post to allow for more leg room. I'm about your size and ended up getting a 52cm frame (would have taken months to get the 56 ordered), and put a 130mm stem and the longest seat post I could find on it. I rode & raced on that for many, many years.
Jun 3, 2016 at 11:54 comment added Daniel R Hicks The first rule is that you should be able to comfortably stand, with your feet flat on the ground, while straddling the top bar. With traditional diamond frames there should be 2-4 inches between the bar and the stuff between your legs. With newer style frames with the slant top bar there should be an inch or two more. If this size is right then most manufacturers will have the bike sized for an "average" person of that "standover height".
Jun 3, 2016 at 11:44 comment added PeteH Go sit on each, and judge which one feels better. Possibly, given the closness of the two sizes, you'll conclude that the answer is "neither", in which case it doesn't really matter. The smaller frame will be a tad lighter and and stiffer.
Jun 3, 2016 at 10:35 comment added Criggie Is your body built to average ratios? Or did your mum always say "he's got long legs" ? Mine did, so I need a larger frame for legs and a shorter top tube/stem for arms. The only suggestion is for you to go try them out. Talk to the bike shop that said 56 cm first (because it agrees with the maker) and get on it. If it feels alright, go for a ride on rollers in the shop, or around the carpark. If it still feels right, go for a ride for a couple hours. Fit is so personal that the internet at large can't tell you the right answer.
Jun 3, 2016 at 8:53 comment added mootmoot My quick and dirty bicycle fitting for top tube : When mount on the bicycle in comfortable posture (not the aggressive racing posture). My head is behind the handlebar but still able to see the front tyre. If you cannot see it, it is too big for you. If your head over the handlebar, it is too small.
Jun 3, 2016 at 8:01 comment added mootmoot top tube length, seatpost, crank size all vary depends on manufacturer. for 5'9", go for 54. Because longer top tube are uncom fortable to stretch the posture.
