Buy for folding bicycle (20 inches) for speeding up
On 2017-05-25 20:26:18
I replaced it with my own folding bike (20 inch). Replacement is no problem, making it easier to put speed. It's good to be cheap and sturdy, but it's a bit heavy.
CP 48T 170 mm

I chose a crank length of 170 mm. Rowing becomes lighter as long. Because it is made of iron, not aluminum, it is resistant to deformation. It is heavy. The weight of the crank right and left is 1.3 kg. Since weight is important for bicycle parts, you should write the weight on the product page. It can say also to other product pages.
Modification of a light car that had been neglected for years

The original crank of a light car has 36T, and because it is dissatisfied with the speed, I also took the original chain cover and made this 48T with W guard. It is not made of aluminum, but I am very satisfied with reasonable price. Weight is not the purpose, so we do not care about weight.

It was hard to use
Exchange of folding bicycle crank (36 T · 165 mm)
On 2015-10-14 15:39:25
Although I could not get the speed with the diversion of the mother-climber parts, it is comfortable to exchange both riding position. However, it is heavy because it is iron. There is no way to say this from the price, but there seems to be room for further weight reduction.
To speed up small cars, exchange

The original gear ratio is too low, so I replaced it. It became just a good gear ratio, and it became possible to use all the rear gear. It is a bit heavy, but it can not be helped because it is made of iron.
For remodeling Mamachari
On 2015-07-24 20:56:20
Material: Crank: Because it is steel, the weight is reasonable. Purchased for the purpose of increasing the top speed by enlarging the front. It seems to be good for remodeling Mamachari. If the crank is aluminum, I think that it can sell even if it is 1000 yen higher.
