I've been riding my fixed gear bike ("Mercy Anne") fairly regularly since we put it together in September. Not long rides, but frequent short rides. Unlike my geared roadbike, I never stopped riding the fixed gear over the winter. And of all my bicycles with drop bars, for whatever reason this one is the most ridable in regular clothing, so if I don't feel like wearing cycling clothes on a short ride I don't have to. I've even ridden it in skirts and semi-high heels a few times; it is surprisingly tame and versatile.
Maybe it's because of that versatility that I find myself constantly fiddling with this bicycle's handlebar height. It's not that my positioning doesn't feel right, but more like all the positions feel equally right and I can't decide which one to settle on. When we first assembled the bike, I had the stem "slammed" and the bars considerably below the saddle. It felt perfectly comfortable, but over the winter I started riding in the city more and decided to experiment with being more upright. So I raised the bars to saddle height, and that felt great also. Then one day I lowered them again just for the heck of it, and that too felt good.
Strange that on other bikes I feel a distinct "sweet spot" as far as handlebar height goes and on this one I do not. Not sure how many times I've raised and lowered the bars now thanks to the easy up/down adjustability of the threaded stem, but it's probably time to settle on one position and stop the madness. How do you decide on handlebar height, and do you tend to fiddle with it after the initial set-up?
