I can maintain a half mph better on the track bike than the road bike at steady state with the same aero wheels, but the indoor wood track and 130 gm tubular tires inflated to 210 lb. may have something to do with that. I think at 190 lb on this bike in a good position on the drops would give me about 22 mph at 200W. My Felt TK1 track frame is more aero than my Cervelo S5 road bike with all the derailleurs, chainwheel, cassette, levers, brakes, etc. and weighs about 4 lb. less.
