    Wattage for a 40km/h TT??

    Like I said previously (perhaps you missed it?), I run a for profit website. I make no money when you do a google search for "normanalized power" and click on the links that are served...if you prefer, I can provide a direct link to the thread, but don't know "the rulez" around here about that...

    Wattage for a 40km/h TT??

    I'd suggest you google "normanalized power" for some old discussions on my views/beliefs of the topic. In short, I believe this when it comes to training: 1)raise the left 2)fill the right 3)scatter the plot 4)run whatchya brung 5)have fun you used a GP derivative as a marketing tool in...

    Wattage for a 40km/h TT??

    comparing yourself to others on internet web forums (where things can often times get biased one way or the other), then, might just wind up being a poor use of your time. This might be true, but, CxA does not operate in isolation (and/or you might not be able to improve your CxA much based...

    Wattage for a 40km/h TT??

    Well, then, I guess that means I should have given you (and others?) less benefit of the doubt when I posted originally? Given the obtuse reply of yours that I've quoted above, I reckon I could have made my initial post something more along the lines of: "Furthermore, I'm _NOT_ surprised that...

    Wattage for a 40km/h TT??

    71 kg +/- 2.5 kg. I'm 1.83m-ish tall. What, exactly, are you trying to assess with your original question?

    Wattage for a 40km/h TT??

    to the OP: 20 km TT at sea level in 29:15 on around 255W average power. Saddle height at the time was probably 81.5cm with maybe 9cm of drop between top of saddle to bars. I think that ride was done using a Trek TTT. But, I've gone faster than that using this bike (watts unknown since...

    Wattage for a 40km/h TT??

    I agree with you that a power meter by itself is insufficient. However, when the OP asks about watts to cover 40km in an hour, surely it is helpful to have one at your disposal in order to ballpark things, eh?

    Wattage for a 40km/h TT??

    I typed "normanalised" which is not a trademarked "for profit" term. i agree that it provides insight - but, rather, it provides insight into the world of marketing and business. In a thread about how many watts it takes to do 40km in one hour, it just adds to the already plentiful sources...

    Wattage for a 40km/h TT??

    going fast on a bike is about supply and demand. supply is the power you can generate. demand is the external forces that must be overcome (rolling resistance, axial force/aerodynamics, gravity, drivetrain losses). increase the supply while maintaining demand and you'll go faster. maintain...

    Wheel Energy

    the H3 is narrow. And even twenty years or so after its release, it is still tough to beat.

    Wattage for a 40km/h TT??

    I've not done a 40k in quite some time, but plenty of 20k's in under 30 min. Happy to offer info on those rides if you like. Furthermore, I'm surprised that folks in this thread haven't offered up that normanalised/gizmo power is not the metric of interest you ought to be after for...

    Wheel Energy

    wind tunnel testing and tires from an aerodynamic perspective, it's been my experience that the tire you choose can be more important than the wheel...i.e, you can ruin the aerodynamics of an expensive TT wheel with a poor performing $75 tire.
