Brand Focus on Shimano

An illustrated history of the world’s biggest cycling brand – the mighty Shimano.

Shimano is the biggest cycling brand in the world. It all started with one man in 1921 – Shozaburo Shimano.

Shimano were something of an anonymous and ignored brand for a few decades. Quietly getting on. Not really pioneering anything major. Nor were they producing little pieces of engineering artwork (like Campagnolo were so famed for).

It wasn’t until the 1970s that Shimano really changed up a gear (ha!) and came out with a few ground-breaking, market-changing items.

This wave of innovation and integration continued over the years, right up to the present day.

Here is Shimano’s story…
