From the children of the driving situation, it seems comfortable stepping unchanged with the existing products. The accuracy of the product is probably enough there.

It corresponds to a chain of 1 / 2x3 / 32.

I gear crank that was attached originally was W guard, outside nor inside because they are made of resin, cracked in aging, I purchased the item trying to repair. This item is W outside of the guard is a metal, I think the inside is long-lasting because it is made of resin.
