Released in 2013, Rikulau Hercules steel tubeset is the newest addition to the Rikulau family. The raw material is from the renowned Nippon Steel (Japan). But, precision extrusion, heat treatment and all other processes are done in Taiwan to assure the precision required by Rikulau. The new tubeset belongs to the 4130 CrMo family, but it behaves very differently from its close relatives. And, the frame built with it is, of course, beyond comparison.
