-Selection of Parts-

We consider that forks and handles are NOT independent; they are integrated with the main frame, and express strength.
We choose silvery parts so that the harmony with titanium parts could be maintained.
In order to emphasize the shape of the frame, we do not put focus on grades and prices of parts very much, but simplicity, perceptibleness of materials, and uncharacteristicness.


It is designed to signify the glitter of ‘Katana.’
A family crest is marked on the sharp wide silvery rims.

-Chain, chainring, crank, pedals-

We adopt a belt drive which has the good appearance and is easy to maintain.
Then, we choose the black crank and pedals which go well with the belt drive.

-Brake lever-

We choose the brake lever for the simplicity of its silhouette and the compactness of the lever.

-Seat pillar-

We currently use the ready-made product, but are planning to manufacture our original one made of titanium.
