• This is a bit misleading - it depends what you are training for.

    Track, TT or flat circuit racing - watts and aerodynamics are the key factors.

    Watts/kg is useful for making a profile but it's a bit like BMI in that it can be a bit misleading. Aside from weight, it also only takes 5s, 1min, 5min and ftp power into account so it's not a totally comprehensive review.

  • Thank fuck W/kg isn't the be all and end all. :)

    There's an aero chart kicking around as well that plots CdA against Watts.
