OTI iron Shafts

July 23, 2018

Mitsubishi OTI iron shafts now in our fitting matrix. Early testing has shown these to be a great shaft. Further information when we have finished testing.

A shaft with no spine is a novel approach by MRC.

Overview

The OT™ Iron shaft doesn’t use traditional prepreg sheet, but instead uses a new material for the golf shaft industry called Tow Prepreg. Tow Prepreg uses carbon fibers that are arranged in super-strong “bundles” (the way a steel cable is made). These bundles are impregnated with resin to create the Tow Prepreg, and then woven together like a braid.

The “braiding” technology using Tow Prepreg is incredibly resistant to twisting and ovaling and creates a shaft with no spine, so the shaft performs more consistently than a shaft made with traditional sheet prepreg. The braiding also minimizes vibration, to provide the better feedback that’s so important for iron play.

We now offer the OT™ Irons in a 0.355" taper tip version.

Technology

Tow Prepreg

Instead of being made with a traditional prepreg sheet, the OT™ Iron shaft employs a new material for golf shafts called Tow Prepreg that contains carbon fibers arranged in super-strong “bundles” -- much the way a steel cable is made. These bundles are impregnated with resin to create the Tow Prepreg, and then woven together like a braid.

Braided Technology
