I do. I've been riding my fixed almost exclusively for the past few weeks, but last night I went on a pretty heavy duty geared ride with one of my co-workers. I found that at the top of my pedal rotation, I was expecting to be carried through; so for the first few minutes there was an awkward pseudo-pause as my legs remembered they had to move themselves through that area. Not only that, but the first few times I coasted were a little awkward as well.
Anyone else see similar issues going back and forth from fixed to geared?
