What kind of power (in watts) is needed for get under 1hour for a 40km TT? What kind of power level does everyone on the list achieve at lactate threshold (ie. what's your 1hour power). It would be interesting to know... mine is 260W.

Well, the figures aren't that interesting without the weight of the riders. A heavy rider needs to produce more Watt than a lighter rider to maintain the same speed. Anyway, my threshold is at 320 W and I weigh 73 Kg

That is an interesting point Ric, I would assume then that SRM cranks give an indication of what is happening at the pedals (i.e. the power produced at the pedals) and PowerTap what is happening at the hub.
I assume that powertap is better when predicting performance (particularly when different bikes are used) and SRM's are better when training (i.e. the riders power output is the same no matter what the bike is).
Is this correct? (I appreciate that the difference is very small!)
