The sprocket is made of ultra duralumin (A7075), hardened with T6 heat treatment, and then machined one by one. The Sunstar 7075-T6 rear sprocket is then anodized in the renowned Koken color to further enhance its individuality. This is a color sprocket made to order.
Points of Attention
* If there may be an instruction manual included, it will be written in Japanese.
It is the anodized aluminum rear sprocket of KOHKEN.
The base of it is the SUNSTAR sprocket, so it has the best rigidity and functionality. Moreover, it is finished with KOHKEN anodized aluminum, which makes it even more superior.
There are lots of other anodized aluminum products sold by various manufactures, but to my knowledge this KOHKEN anodized product is the best. Top quality indeed.
Not only it is beautiful when it is new, it keeps on to be that way even when a year or two passes by. You can't detect fade or change of color, caused by ultraviolet light. That anodizing technology is nothing that can be seen elsewhere.
Anyway, this KOHKEN anodized rear sprocket is superior in its design and function.
As it is first class, it turns out to be a bit expensive, but it's worth it.
It is made of aluminum, but you can count on its durability. You won't be able to tell the abrasion of its teeth.
Also, this rear sprocket is really light compared to the original one (steel made), for it is made of aluminum. So you can expect the reduction of its gyro effect.
My overall evaluation for this product is 5 stars.
I know that it is an expensive item for a dress up part, and you might not earn enough effect for spending such money. But its structure is superb enough to tell the high manufacturing technology of Japan.
I would surely recommend this item to ones who are looking for an aluminum anodized rear sprocket.View Detail
