NarumiBicycleDesign mainly uses titanium alloy. Titanium alloy has many types of tubes that can be used for bicycles compared to steel.Lightweight. In addition, it does not require post-welding heat treatment like an aluminum alloy frame, so even if you omit the process, you can obtain the same strength as steel.titanium isAlthough it is difficult to process, by outsourcing it to a factory specializing in titanium, which is good at manufacturing special single items, we can realize a wider variety of designs than steel and aluminum alloys.
