    SPD and torque sensing drive

    Yeah its the 'scissor' action at bottom and top that makes the difference I think, you can hear the difference on the turbo trainer with and without. I do reckon the up pull is advantageous (to me anyway) as I can certainly feel the burn in the top of my legs so obviously using different...

    SPD and torque sensing drive

    For sure, although the motor control system will have to interpret a different signal both amplitude and phase) which is where I came into this thought process. I know for sure that with clips I deliver power over a much greater rotational angle, so as far as I can tell the only effect will be...
