Roughly divided into two types
The most popular type, easy to put on and take off, and many of them are reasonably priced.
Shimano, LOOK, Wellgo, etc. are based on this type.
It takes a little trick to put on and take off, but once you put it on, it's comfortable.
Keywin: Compared to other types where the cleat and pedal rub against each other
Since the shaft itself moves left and right, it is difficult for the mother and child ball axis to shift.
Speedplay: round pedal
The tread is short but light.
The shaft center becomes the rotation axis (behind the mother and child ball)
The cleats do not come out, so you can walk.
The big difference between LOOK and TIME is primarily in the core of the cleat movement.
The cleat, which is attached to the sole of the shoe and attached to the pedal, moves left and right on the pedal. This is especially convenient for Japanese people, as the ankle moves left and right as the leg moves up and down (rotation). This move
It moves around one point with the cleat of the pedal, but in the case of LOOK, it is the front of the cleat.
In the case of thyme, it moves directly under the mother and child ball.
If you move directly under the mother and child ball, you will feel less discomfort even if you are actually moving.
Most are aluminum, but some use magnesium.
Steel shafts are standard, but titanium is also available.
The one supplied for professional use is a high-end model with only the mark, and the inside is made of aluminum.
The reason is durability.
Simply put, the width of the stepping position
If the crankshaft is long, it will be stepped on the outside, but this means that the Q factor is wide.
In the case of Time, the cleats can also be adjusted only in the fore and aft position, and can also be moved left and right on the pedal.
Recently, there is also a function to adjust the horizontal movement called the Q factor, but Japanese people with a wide pelvis have almost no problem with narrowing the Q factor of the time.
Most of today's pedals move left and right, and the main reason for this is that the direction of the ankle changes when turning.
If you try to rotate your leg with an imaginary movement, you can see that the outside of the sole of your foot is tilted.
If this is fixed to the rotation of the pedal, it will be converted to the left and right movement of the ankle, so the cleat will move left and right.
