Description
If you like beautiful steel bikes, we have the perfect T-shirt for you.
CIRCLE'S has been fond of bicycles made of chrome molybdenum / Cr-Mo (commonly known as chromoly) since the company was founded. People often say it is "heavy" or "rusts," but when it comes to safety and longevity, Cr-Mo bicycles are the most reasonable choice of any material.
It is actually a very gentle material that, in the unlikely event of a crack, will not suddenly snap, and in many cases will make a recognizable sound to warn you of it. And even if it were to become scrap iron, it can be recycled again as a steel material.
Robust, long-lasting, safe, repairable, and recyclable material. It is a material with many sustainable elements, and these characteristics are not found in modern materials like carbon. Steel bicycles are not just a classic, nostalgic ride, but the best realistic option yet.
After all, a thin and beautiful steel bike is always cool and admired.
The body is made by CHAMPION. It is a relaxed fit with ACTION STYLE's original sizing, with a relaxed body and sleeve width, and a slightly shorter length to balance the silhouette when worn. The product washing process gives the garment a familiar feel from the time it is first worn.
