Hi guys, I'm 5' 9.5", I have an inseam of 31.5"
I currently ride a 55cm bike. I'm searching for frames... for a 2nd bike. I feel that the 55 might just be a hair too far of a reach when trying to hold at the hoods. I can still ride in it for 6 hours + without many issues, I just wish it was a hair shorter sometimes. 53 is much too short. I feel if the bike were a 54, it would be a best fit for my reach. Most frames that I like come in 53,55,57 and not so much 54,56, etc.
Perhaps I should get a 55 that I like and just buy a slightly more compact stem to microfit adjust the bike to my liking? I've heard that most of the 5'9 - 5'10 guys ride 55's anyhow.
