Search term of the day, “Will a 56 cm bike fit a man of 6’2″?
Welcome to my shortest answer, ever:
I’m 6’0” and have a perfectly awesome 58 cm bike, a 56 was too small for me. I believe my ideal size is between 58.5 and 59 cm, but those sizes aren’t available… Other important measurements: cockpit length: the distance from the nose of the saddle to the bar top (some use seat post to bar top). Crank arm length and about a dozen others. Get measured before you buy, then get the bike fitted to you. It’s not a cheap process, but it is worth it.
