Hey hubbers... I've been commuting since May this year... starting off with a mountain bike and now recently bought myself a road bike... since I travel +/- 30km one way i thought a lighter/faster bike will be a bit better. I'm 1.63m tall and my MTB was 46cm... that was nice and small for me. I've read that bike size is important and looked at this before I got myself a road bike: https://www.ebicycles.com/custom/content_files/ebicycles-bicycle-sizing-chart-road-bikes.pdf Which actually indicates that a 52cm road bike should suit me perfectly. I then got myself a 50cm bike.... but it seems to be a bit too big for me. The seat post (mike burrows) is 2 shaped and can't go as far as a normal one and that prevents me from setting it perfectly. My legs are straight when I reach the pedals instead of a bit of an angle. I can ride like this but I know if I can get a small angle at least it should be more comfortable. Not sure if straight leg is okay? Do you guys suggest I get a smaller bike or get another seat post? or any other ideas? Thanks Eustace
