Had another crack at this from a different angle.
I posted before on power data obtained under 'ideal' conditions (flat/no wind) and also on a short hill climb. I've now extended this to compare the efficiency of two of my bikes over longer, mixed conditions riding and came up with a couple of interesting results (but beware, small sample size!)
The upright is a Planet X Team Alu, the other a High Baron:
Read it at
recumbent vs upright efficiency.
As usual, thoughts and feedback etc.
I don't suppose anyone knows anyone who would lend me a crank-based power meter to use (on a turbo) to measure drivetrain efficiency for a couple of days? Modest beer tokenage available...
