So here's the deal. I just finished building my new bike and decided to go with a 53. I'm 5"8 and a half with a 29.5 inseam( yeah i got short legs) . I took my bike out on a ride today and I feel so uncomfortable. So after I did the Bike Fitment measuring calc. online,I realized my body's really unproportioned. When i'm standing over my bike, my top tube is about 1.5 inches from my crotch. Am i just screwed? wth do i do to fix this. i have a 90mm stem with 10 degree drop. should i get a longer one? Here are my measurements..

i guess set your seat a little lower get a longer stem or if your bike is new sell the frame and get the one that fits you

where are you most uncomfortable on the bike then? play around with the stem length and the height of your seat

when i'm sitting on the bike and leaned over in the furthest part of my bullhorns, my head is in front of the front hub.

the best thing i can say is go to your LBS and have them figure it out for you from what you have and your problems you are having cause bike fitting over the internet wont help that much

Jesus! I have a similar problem, though am about 5'7". My torso is long, my arms are very long, and my legs are short. I can either ride a small frame with a setback seat post and long stem and still be a little crunched, or ride a larger frame with normal post and stem and ensure that my son is an only child.
Since I'm not about to be able to afford a custom frame, I was thinking about buying a larger mountain frame (20 or 21 inch) and building it up as a road bike. I have yet to try this, but the elongated mountain geometry may make some sense with my build. You're obviously in a different boat, since you're riding track...

BikeCad might be able to help you figure it out.

well i went to my LBS today and they didn't have time to size me up, we'll find out the verdict next week after 50 bucks and some measurements. I flipped my stem over for now to a 10 degree rise instead of a drop and it's a lil better

50 bucks is kinda steep though dont you think and at the end you still gonna have your bike and stuff and maybe just to change 2 or 3 things on your bike

$50 is cheap for a fitting.
some shops charge up to $200 for a bike fit. it optimizes your ride quality and increases performance output.
better to pay the $50 and buy the exact sizes you need then play around with sizes till you find it.

I've never paid for one or anything, but even a good fitting isn't going to make us mutants fit things perfectly. Me mutants.

i completely agree. i haven't done this yet but plan to: for $200- $250 i can go to someone certified in bike fitting and know my ideal measurements for every single aspect of the bike (and future bikes). yes spendy but i've spent and lossed (and continue to lose) more than that much swapping out parts the help but don't ever fully dial me in to feeling "right" on my bike. there are much cheaper fits like the $50 you mentioned but that might take 15 minutes, this, up to 4 hours.

Yeah, that's like saying that knowing your shoe size won't help you find shoes for your weird feet.

well, thank god i got the frame size correct. Now it's all about stem length and saddle position.

i was thinking maybe it was because i was riding my buddies 56 for awhile and it was too big and I got used to it. I did feel more balanced on a bigger bike and it was for sure easier to stop without feeling like I was going to flip over.

Yeah, ride it for a while. Adjust the saddle forward and back to get your legs right, then swap stems until you get the reach comfortable.
