How to adjust the step frequency to get the best energy output power ratio during the carbon bike riding?

The tread frequency is the number of times a foot turns in a minute. That is, by increasing their frequency ability, to save limited energy and lactic acid tolerance in muscle. Whether you're on a highway or a mountain road, you can keep your number of tramples on the optimal frequency without paying attention to the speed, and get the best energy output power ratio. Reasonable and correct tread frequency can also effectively prevent knee injury. Usually, the amateur nature of long-distance riding, to maintain the 85-95 pedal frequency is relatively durable, not easy to produce physical decline.

Step frequency training is a long cycle of conscious training process, we should pay attention to keep the body stable at high step frequency, so as not to cause the body's left-right swing and up-and-down beating due to the increase of step frequency.

Flat road 90-100 is a better tread frequency, climbing a long slope is generally 70-80.

If there is no pedal frequency device, you need to remember the speed of various gear pairs when the pedal frequency is 90 and the speed when the pedal frequency is 100. Then watch the code table to show the real-time speed, adjust the transmission, so that the pedal frequency can always be maintained between 90 - 100. With the first 2 and the second 5.6, the speed can be maintained at 22 to 25 km/h, which can be a good practice of tread frequency. Each ride lasts about five minutes at this speed.

When they learn to control the trampling technology, it's time for them to do long-distance climbing training. At this time, the training objective is to adapt to trampling on the seat bag during the long-distance climbing process. This is the way to increase your stampede strength, which can be used to the maximum extent under certain conditions of riding!

The big disc is 42, the middle disc is 32, and the small disc is 22.

The number of flywheel teeth is 11-13-15-17-20-23-26-30.

Carbon bike wheel circumference is 2.08M

Speed = tread frequency * 60 minutes * gear ratio * carbon bicycle wheel circumference / 1000

When the tread frequency is 90 rpm, the speed of each tooth number ratio should be as follows:

Corresponding Speed of Gear Corresponding Tooth Number Ratio (km/h)

1 x 1 (22/30) 8.26

1 x 2 (22/26) 9.6

1 x 3 (22/23) 10.8
