im currently in the market for a track bike. this will be my first bike that is not a bmx. i'm 5'11 and very average build. what size frame would u suggest for optimal control/ speed

53cm im guessing

it varies widely depending on what you're shaped like and who you talk to, your best bet is to go to shop to get sized.

second best is to look online to find a sizing tutorial and measure yourself.

most/many folks find that a track bike 1 -2cm smaller than their road bike feels about right.

at a guess, 56cm - 57cm

i'm 5'8" and ride 53cm,

my new frame is gonna be 53cm and i'm 5'10ish... however, i have shorter legs and a longer torso so my top tube is gonna be 56.5

i'm 5'11" and ride a 51. all torso, no legs. measure your inseam, look at available specs for track bikes and get a feel for the standover height of different size frames.

whats your inseam?

i'm 6'2" ish and always ride 58cm. 58cm on a track bike is suiting me fine so far.

um, so as far as that pertains to you, it'd be, go by your normal size, and get something smaller than 58 cm, since you aren't 6'2" ish.

Weird. I'm 6'1" and ride a 59cm Steamroller.
But it ain't no track bike. Sure is nice and comfy though.

I'm 5'10" and ride a 57. I have kind of long legs for my body though.

huh. I'm 6'0 w/ 31 inseam and have a 55cm frame...

Why does this get two threads of equal length?

one for each leg.

I'm 5'11" with a 32" inseam. I have broad shoulders and long arms. Both my road and track bikes are 56cm with 56cm top tubes.

According to the old formula, you know, that inseam x .833 and add the age of your cat thingie, I should use a 58cm. I've found that a smaller frame with a long stem fits me better than what Conventional Wisdom might suggest. For me 56 is the smallest I can go. I once had a 55.5cm Ciocc road frame that I just couldn't get to fit right, so 56 it is.

Focus on the top tube length. That dimension cannot be changed, and it's very important in how the bike fits you. You can always use one of those three-foot-long mountain bike seatposts to get the saddle in the right place. That Ciocc frame had a 54.5 top tube, and even a 150mm stem didn't make it right. And having your brake levers arrive several seconds before the rest of the bike due to the extreme stem length makes for a pretty unstable ride, because you end up with too much weight over the front wheel.

the last time i checked the equation, i missed the thing about the age of my cat, but if you want to do a little measuring and a little math, the equation is on this site:

Finally! Someone else who has noticed the biggest screw-up in the histroy of cycling. Seat tube length is almost irrelavent, since it's so easy to change. Standover is even more irrelavent, unless you spend more time standing over your bike than riding it. But top tube length is impossible to change (except by stem length, but this can effect handling if it's less than ~80mm or more than ~140mm), and will have the biggest effect on comfort for most of us. Get your arms and body comfortable, and your legs will take care of themselves.

My advice to you would be to try as many bikes as you can (track or otherwise), in whatever size you feel is best. Get an idea of what measurements (horizontal TT length, and from the saddle rail clamp to the bar clamp) suit your body, and work from there. Seat height and stem length and height are easily adjusted once for optimum comfort (or aerodynamics).
