Sort of my first proper fixed... 1st impressions.

polybikeuser By precarious I mean a bit jittery and nervous feeling, just not as solid as I usually feel on a bike. Stem's the right length and the bars are the right height, maybe a smidge lower than ideal, but I just don't feel entirely comfortable mixing fixed riding with bullhorns on this bike, think with risers it'll be fine. I'll just have to put together another fixie on which the bullbars do feel right.

You should, imho bullhorns are the best bars on fixed gears.. and imho they make it easier to do skidstops ;)
