Fitting Your Bike Are you confused about how you should fit a bike to your particular body dimensions? Have you been reading, found the terms Merxx or French Fit, and don’t know what you need? Every style of riding is different- in how you fit the bike to you, and the sizing of the bike itself. It’s more than just measuring your height, reach and inseam. With the help of Bike Fitting, you’ll be able to find the right fit for your frame size, style of riding, and your particular dimensions. Here ya’ go…..the location for everything fit related.

Frame size or New Stem question!

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.

I'd go for a slightly too small frame and then adjust the stem and saddle height to fit.

Are there any downsides to going with a frame too small? Such as handling or geometry that I should worry about?

Less than going too large. Too big is just that. Not much you can do. Too small? Can be dealt with. I'm riding 6cm too small on one bike. 52cm when 58 cm would be ideal. Took some modding but iti can be done. Take though a less
extreme example. I need 58, I have 56. No problem, taller seatpost, longer stem. I have a 60 and need a 58? Itws just goiing to feel wrong. You can shorten the stem, but can't do much about the seatpost.

Going small you might get shoe overlap on the front wheel just adjust technique.

For this kind of bike, yes. Racing / Group riding.
