Chain brackets were not attached to the inexpensive city cycle, and troubles often occurred in which the shaft attachment part shifted due to long-distance operation and the tire contacted the tire stay and it did not move. By adding this product, it became possible to fix the rear wheel shaft to the position where the tension condition of the chain was finely adjusted. This product is somewhat dissatisfied with the point that bending occurs, because the material is slightly soft. I want you to make it a bit thicker, change the material and increase the strength. I do not mind raising the unit price to that extent, but I want you to sell it in 2 sets.
Package goods (1 piece included) such as home centers are expensive ¥ 248, so packs of 10 packs are extremely costly. We do not know the rust prevention ability in the long term, so I do not know yet, but I think that it should be divided as consumable items.
