    Ahogy latom most nagyon ra vagy kattanva ezekre az avg speedekre, akkor egy kis szamtan, hogy hol lehetnel megfelelo "celszerszammal" :) Eleg erdekes szamok

    ...this test done by German Tour Magazine.

    They tested Uwe Peschel with all the different aero bits, and you can see how much drag was cut when each change was made. Once again, I think it's on an indoor velodrome

    Required output to maintain 45 kph on a:

    Standard road bike, hands on hoods = 465 Watts
    Same bike, hands down on the drops = 406 watts
    Same bike with aero bars = 369 Watts
    Same bike, triathlon position (5.5 cm lower bar, saddle forwards)= 360 Watts
    Same bike, as above, with 2 tri spoke wheels = 345 Watts

    Cervelo TT bike with 2 tri spoke wheels = 328 Watts
    Cervelo TT bike with tri spoke front & disk rear = 320 Watts
    Cervelo TT bike, tri spoke front & disk rear + aero helmet = 317 Watts
    Cervelo TT bike, same as above + skin suit = 307 Watts
    Cervelo TT bike, same as above, with saddle pushed back 3cm = 293 Watts

    From 465 to 293 watts!! That's obviously a reduction of 172 Watts just from aero stuff...
