is anyone riding steep geometry (75/75 give or take a degree) in conjunction with a relatively upright posture (ie- bars flush with the saddle or higher)? i'm debating on the purchase of a technomic stem specifically for this purpose, and to the end of achieving a more comfortable position conducive to longer rides. share your thoughts and opinions.
That's pretty much the setup on my favorite fixie. I use it for messenger work and 'round town riding...usually 40-60 miles each day that I ride it. The setup works well to keep me comfortable. I've actually got the bars about 1 inch above the saddle, and use a 60mm stem and noodle bars, so that the reach is super short. If you want to try this setup, though, key is to have a very comfortable saddle. Right now i'm using a terry fly, which is about as comfortable as 'fast' saddles get, but I'm thinking about swapping it out for something wider, like a liberator (6.5 vs 5.5 inches wide...my sit bones are pretty far apart.) This is important because a pretty high percentage of your weight is on your bum!

[the] key is to have a very comfortable saddle.
adding to my prospective list of items, then, one brooks saddle.
i was just talking with a friend of mine about this yesterday. he, too, is a messenger and equates the position he's in to running and being in control. it seems to work for him. he's one of the craziest, fastest, most in control riders i know. i'm riding with him tonight, i'll take a better look at his setup.
that probably didn't help much.
74 head tube angle and 75 seat tube angle I ride. No My seat is always higher to my stem and bars. When riding like this you need to ride correct position . That includes any bike.
I see guys riding with tip down seat and complain alot later. get a fit done so you know what you ride.. we no longer call a stem a NECK so why ride like we still kids with no knowledge.

i ride the same geometry as you (74/75).
when riding like this you need to ride correct position
by 'like this', do you mean with those angles? also, by 'correct position', do you mean aero?
I mean by getting a proper fitting done to your bike. Anybody that know me , they can tell you I can tell you what size I ride st, tt, cs, wb and stem and bars sizes for ROAD AND TRACK BIKES.
I was with a keirin racer and a road racer here in Japan and they was amazed that the short cuts I knew that I could tell the frame size of there bike and the angles. It is Me , I am anal when it comes to stuff like that sometimes.
I learn short cuts and sometimes carry a ruler. You learn this after years of riding and watching pros set up there bikes. Even they after years of riding when they set there bikes up they know what is wrong with it and tape measure comes out and fix the problem.
Get a FIT KIT or Serrotta fitting done.

ceya, it's not a question of size, as my frame fits me just as it should. there are certain riding positions, though, that are more conducive to long rides and commutes, as i mentioned previously. this thread is nothing more than an attempt to ascertain weather it is indeed possible to successfully achieve such a position with seemingly conflicting frame geometry. i appreciate your assistance in the matter.
A proper fit just not help you with the size of your bike but with what you are looking for in riding positions.
I have my standard riding position but can change slightly to achieve if I use my Panasonic to ride track then change slightly to ride cyclocross in the winter and messenger work. Which all have been done.
You need a base and from which type of riding you want to do with that bike you can alter it.

my angles arent steep (i think 73.5->74 for both) but i have a saddle->bar drop and i don't like it much.
not that im not flexible or anything, because i can rock it on a normal road set up.
however, on the fixie--without brake hoods to lean on; having my ass high up and forward; and having to constantly spin--its nervous riding downhill... bumps on the road tend to jolt me a bit upwards (out of saddle) and i have this unsettling feeling ill soon get tossed over the front-end from hitting a random bump or a big crack...
maybe ill get some tires with much more volume
or you can lower the seat if you have a relax angle but have that high up feeling. My Panasonic has a relax position as well.

I ride a Bianchi Pista with the flat of my bullhorns the same height as my seat, but the horns turned up a little to match the natural angle of my wrists and grip.
I feel upright, but when I see myself in a window, I look like most of the roadies I see, in terms of uprightness.
