I'm between 5ft7 and 5ft8 inches. Would a 52 or a 54 be a better fit for me?
yes, no, or maybe. Take your choice (NM)Rusty McNasty

I think Rusty's point is, as you see from much of the discussion here, that size cannot be judged by just comparing rider height to a generic cm number. Rider height is a combination of inseam, torso length, and reach; frame size is a combination of top tube length, seat post angle, and seat tube length. Different manufacturers also measure differently.

You'll want to test ride, test ride, and test ride. And also slap it on the trainer at the shop and get eyeballed for fit, reach, etc. It is a question that can't be answered in a vacuum.

That all being said, I'd be surprised at your height if a 52 cm by any company (but especially any that measures center-to-top, is big enough). I'm 5'7" and I rode a 52 in one mfg. and a 54 in another.

I've got a 52cm I'm trying to sell because it's too small. The weird thing is, I'm 5 foot 10 inches tall and it's really not THAT small for me. I pulled out the seatpost a little and got a 140mm stem and the ride is really quite comfortable for the first 10 or 15 miles. The only reason I'm trying to sell it is because I favor rides of 40 or 50 miles and after about 30 on this bike I get a little cramped.

It's all a matter of feel to the individual. I like being low and having my thighs almost horizontal at the top of my stroke. It feels more like a squat and I can really haul some butt that way. Plus, with the bike being a little small for a rider my size, I can cut corners like you wouldn't believe and can really get aero when I want to.

Logic would say a 52 would be too small for you, but since you're two or more inches shorter than I am and I'm not really bothered by the 52, you might find you like it. It's all a matter of what makes you feel good when you ride. If I was a crit rider or time trialer I'd keep my 52 because that frame size suits THAT style of riding FOR ME, but I want to just kick it for a few hours and comfort is becoming more important to me than speed, so I'm looking for a little bit more room on a frame. I've been professionally fitted with a Fit Kit and I only need a 55.

You might like a 52.
