About Shimano

In February 1921, Shozaburo Shimano opened Shimano Iron Works in Higashi Minato in Sakai City when he was 26 years old. On the site of a demolished celluloid factory, he rented a nearly 40-square-meter area. The monthly rent was 5 yen. At that time, the new establishment had only a single lathe, measuring about 1.8 meters long. Shozaburo Shimano decided to produce freewheels. Of all bicycle components, freewheels entailed the highest level of technology to produce.

Since then, Shimano has released some of our favourite cycling products with the current Ultegra Di2 Disc groupset being our pick of the bunch.
