Singlespeed & Fixed Gear "I still feel that variable gears are only for people over forty-five. Isn't it better to triumph by the strength of your muscles than by the artifice of a derailer? We are getting soft...As for me, give me a fixed gear!"-- Henri Desgrange (31 January 1865 - 16 August 1940)

no 6 0 person is the same and the OP needs to figure it out for his/her self. this same exact post pops up every week and needs to be locked.

and actually the op says the build is in process so maybe they are going to shrink or extend the bike based on our recommendations...neat!

competitivecyclist.com has a fit calculator to get you in the ballpark. I suggest you get fitted at a LBS that does it a lot. Serotta has a course to get certified at bike fitting; if the LBS has that, you're good to go. SheldonBrown.com has articles and links on bike fitting; good stuff to read.

Your inseam measurement would be more useful that your total height.

Example- my inseam is 30 in. The average size of my bike collection is 53cm.

Heres a VERY rough suggestion: Multiply your inseam inches by 1.76 and interpret the
result in cm for the frame size you should try.

There are way too many variables to adequately cover this in a simple forum posting. I'll tell you what I ride and why, maybe that will help you determine your needs.

I'm 5'10ish with a 33" floor to pubic bone measurement. My main road bike, a Surly LHT is a 56cm frame, but the fixed gear frame I just ordered is a 58cm. Why? Surly frames tend to have longer top tubes for a given size. My LHT has a 570mm effective top tube, but the fixie, while a 58cm, also has a 570mm top tube. Different "size" bikes, but same effective top tube. If the top tube is the same length between two models, I prefer the larger frame to reduce saddle to bar drop, but you may want more drop and prefer a smaller frame if the top tube measurement is the same.

So, we have three variables here: Standover, top tube, and fit preference. Standover is easy to determine by measuring from the floor to your pubic bone. Top tube length is easy to measure, but hard to determine what is right for you unless you know from experience. Fit preference is even harder to determine for a 3rd party. I prefer a more upright riding postition (as shown by the stack of headset spacers on my bikes), but you may want something lower.

What do you ride now? What are the frame dimensions? What are your dimensions? What do you like/dislike about the fit of your current bike(s)?
