But ANY power meter can be used to test if your technique is better.
Better at what, ?
Quoting from 'Measuring Pedal Forces' by R. Bini and F. Carpes.
" Bicycle components have changed over the years to minimize resistive forces and energy cost for pedalling with purpose of maximizing cycling performance. Along these lines the assessment of forces exerted by cyclists is important for the analysis of pedaling technique and anticipate injury risk factors.
Cyclists continuously aim to produce maximal possible power output for longer duration, particularly when power delivered to the cranks can be translated into bicycle speed. To ascertain the optimal transfer of forces applied to the pedals to cranks, the measurement of pedal forces and pedal motion is critical for the development of interventions with focus on increasing maximal crank torque. An alternative approach is to define a given speed (or power output) and to seek for alternative ways to minimize peak crank torque and pedal forces in order to maximize the use of pedal force application."
Anquetil used this alternative approach.
maybe you could show us a video of this aternative approach you speak of. I would really like to see it. thanks
That's the best I can do. In that close up on the track finishing straight he is applying the same maximal torque at 12, 1, 2 and 3 o'c. By extending the range of your max torque sector from 30 to almost 120 deg. you can increase power output from your pedalling power stroke while reducing your peak force/torque.
That is incredible that you are able to perform that analysis so accurately based on a simple youtube video. To think that the 'experts' send thousands of dollars on high tech equipment to test the same things and somehow don't find as useful a solution as you have. You should really find a way to validate your technical assessment and revolutionize bike racing for everyone!!
That analysis is not based on his videos. We both discovered this same extended maximal power output technique. I don't know what led him to it but I found it as I attempted to biomechanically combine arm and leg power. I got the idea after passing a physically handicapped rider who was powering his trike with his hands/arms. This technique needs a special bike set up so that the imaginary leg power application and arm resistance lines are parallel. That probably explains why Anquetil's bars were set higher than what was customary for that period. The videos only confirmed we were using identical power generating techniques.
