Hi everyone. I just wanted to get someone else's opinion on an opportunity I was presented with. I currently ride a 2016 giant tcr small. I have changed out the 90mm stem and put a 100mm stem since purchase. I was presented with an opportunity from a family member to be given a 2014 giant propel isp size medium. I looked up the geometry for the giant propel and it says its a size 52 frame with a 55.5cm length top tube. My current giant tcr has a 53.5 top tube length. In short would the 2014 giant propel in medium be ok for me if i shortened the stem some? I feel pretty comfortable on my giant tcr small but i was wondering if i could just use a shorter stem on the propel if i got it. I forgot to add that my inseam is 78cm and my height is 167cm.
