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)

Single Speed Frame Size

Judging by the length of the seat posts of most SS/fixed bikes, do the guys riding them buy smaller frames? On my road bike, my crotch barely fits over the top bar (I was told that it was the proper size.) so my seat is pretty low...

The primary measurement is the top tube and cockpit length.

People ride smaller frames because A.) they get to raise the seat, B.) which makes them look like teh tracksters!1!
Next ten people will post saying 'that's not true', but nine of them will know it is.

It's not just the single speed track frames - it's all modern "compact" frames that end up looking like that. When there is a sloping top tube, the traditional standover measurement means nothing since the seat post starts much lower than it would with a level top tube. And the results is miles of seatpost sticking up to get the right seat height...

One of my bikes is 60cm,(attached file) and still has a good length of seat post to make the saddle height correct.
I have another bike that's 57cm, sloping top tube, (see link) with a mile of seat post. They both seem to fit me well but I have never had a pro fitting, just go with what feels right.
