Beta Steel
The material is German stainless steel, which is made from more than 50% recycled materials. The frame is made in Korea.

The material is called Beta Steel, but to be precise, it is made from stainless steel.
Stainless steel is made from metals and elements such as iron, chromium, and nickel, and has the characteristic of being "rust-free." It is a material used in watches, etc. On the other hand, regular stainless steel is known to be the most allergenic material because it contains nickel, but Beta Steel does not contain nickel. It is a material that is less likely to cause metal allergy symptoms while retaining the characteristic of not rusting. In addition, this material is stronger than beta titanium, so it can reduce distortion during use. More than 50% of Beta Steel frames are produced from recycled materials.

All rim wires are manufactured in Germany, and final production is carried out in Korea.
