“When you are running you measure your speed of running and your heart rate you can do this in swimming you can do this in All Sport but not in cycling in cycling you need the power to describe because the speed doesn't tell you anything.”

“The spider is already free of all the not wanted forces because on the spider is only transmitted the torque to the chain ring and nothing else. Let's say look in a mountain bike you stand on the cranks you do a descent you jump on the cranks you have no force on the spider as long as you're not pedaling.”

“If you put the weight on the Chain ring the force goes Direct in the power meter and it doesn't matter what the friction of the BB is so it's the better calibration point is the chain ring.”
