I don’t know the aim and the purpose of establishment of JASCA. As long as read this booklet, it didn’t limited for introduction to products, but educationg including function of sports bicycle and method of using method, point of composition and adjustment, selection of bicycle parts .

I posted each page at below. However, I didn't put my comment. The letters in the catalog might be too small. So I prepared E-book. You can turn each page as real catalog, and zoom it. URL is below. Note: advertisement which doesn't relate to the catalog would appear because I use free service.
