Why don't people understand? ... the flex obviously creates heat (that's where the 'untransferred' power goes), and it's that that creates hotspots on SDP pedals. (This is why I like SPDs on cold days, as they keep my feet warm, obviously.)This "transfer of power" garbage....
So what if a shoe flexes? This will reduce the efficiency of transfer of energy from your leg to the pedal. But the unflex works in the opposite way. It's a closed system, efficiency losses equal efficiency gains.
Some cynics might claim that pro cyclists all use the most expensive kit (and the stuff that wears out fastest) because their sponsors tell them to, but I can't believe that to be true. I'm sure Shimano et al would be happy for pro riders to be using a system that is cheap as chips and lasts forever, as it would save them having to continuously supply new stuff - what a bore!
