It is a sprocket hub with a novel design that no one has ever seen before.
While inheriting the functions and ideas of the Takumi floating sprocket hub that we have been supplying, we have increased the number of teeth that make up the tooth drive from 6 to 15 to improve durability and operability.
In addition, by adopting a sprocket fixing method with a retainer ring without using any bolts, the weight of the bolts and fixing parts has been greatly reduced, and it has become possible to simplify and shorten the time required for attachment and detachment.
・Friction reduction by floating
・Lightweight sprocket hub
・Improve workability by boltless
This is a proposal for a winning drive system that satisfies three requirements at the same time.
*Sprockets are sold separately.
* Only the dedicated sprocket “Triple K Sprocket Tsubasa ~AKIRA~” can be used.
