Roddio I-Series Iron & Utility Shafts - TSG has a long history with Roddio starting back when it used to be owned by Daiwa / Globerider and ONOFF. Since then the brand was purchased by the Sports Life Group yet still maintains its RODDIO shaft manufacturing in Higashikurume, Japan at the ONOFF factory.
These are the Roddio I series Iron shafts which have also been a popular standard option in the ONOFF golf clubs for TSG customers. This particular shaft is designed for both Irons and Utility clubs using PENTACROSSWEB (penta cross-web)" sheets for tight dispersion, great feel and excellent distance.
