About Us

First of all, we have started our factory as one of carbon fiber parts development in Japan. Mainly we made any products for motorcycles and automobiles. Also we did repair the carbon fiber, especially CFRP(Carbon Fiber Reinforced Plastic). One day we realized We got several requests for carbon repair of bicycle frames. Then we have focused the bicycle business. Still making carbon fiber parts for motorcycles and automobiles but not many.​ Nowadays we are the top of bicycle frame repair company in Japan. Not only we do fix carbon fiber products but also we can paint like a genuine color or customer's request in the same factory.

The CDJ big pulley kit is one of most important products for us. It's been changed 2 times, much smoother, much more effective. We are still trying to make it better.
