I'll offer up a slightly different perspective on bike fit, from the "train how you race school of thought." I like to make my track bike and road bike a close as possible. So after a year of riding mismatched bikes, I found a track bike with geometry/fit very similar to my road bike. I went with 40cm track bars and downsized my road bars to 42cm(from 46). My track bike feels like it fits like a glove - the position was 100% natural from day one. For my pursuit bike, I bought a time trial bike with the same geometry and matching clip-ons, so that I can work on my pursuiting on the road. While training on either road bike, I make an effort not to coast, but I must admit to shifting since I'm not climbing 13% grades in a 90" gear.
Is my track position sub-optimal? Probably. Is my road position sub-optimal? Probably. Do I think it works for me? Sure do.
