OK, here's the poop. I'm new to riding my single speed/fixie Lemond Fillmore. I've ridden about 1100 miles single speed (including the AIDS/Lifecycle ride from SF to LA last week) and I've ridden fixie about 120 miles. My gearing for the single speed is 42x18 and 42x17 on the fixed side. I've also ridden Mt. Diablo (a local 3800' mountain in the Bay Area) on the single speed. I've found anything over a gradient of 12% has me just about falling over. Also, spinning faster than 21 mph on the flats or descents have me spinning out of control but that's getting better the more I spin. My rides are just about in the 30 mile range on the fixie. I've done several 100+ mile rides on the single speed.
My questions are;
Since I have brakes on the front and rear, I find myself using then a lot on descents. Normal?
Also, and this is an observation (daah), fixed gear riding is a lot harder than single speed. Butt issues, stretching, spinning all the time, jeesh! I have these momentarily lapses of consciousness and try to freewheel and whoa! I try to avoid that! Does that go away?
My intention is to ride as much as I can on the fixie to get in the pocket and feel comfortable.
