I don't think I did. My post was pointing out that the big wattage savings suggested by Dalai's post, from moving from a road bike to a TT bike, weren't realistic. The OP could put aero wheels on his road bike, he could adjust the position by fitting a longer stem, moving his saddle forward and getting the bars as low as possible by removing spacers (if any) and flipping the stem to a more horizontal position if he hasn't already done so. Once he's done all that, the wattage savings (according to those German tests) made by moving to a TT bike without the disk wheel, speedsuit etc would be about 5%. Not insignificant, but nowhere near what Dalai's post suggested.
