Mitsubishi OT Iron Shaft by FRANKI – Last year TSG visited Mitsubishi Japan at the Tokyo Golf Fair and saw several prototypes labelled FRANKI they were extremely light weight as in less than 25 grams!!! Just this week Mitsubishi Japan is showing off it’s official creation the OT Iron Shaft by FRANKI.
Who is Franki? I have no clue but this shaft has peaked our interest as it is a major departure in how carbon shafts are made. Mitsubishi’s goal was to create an affordable and highly capable iron shaft that has the soft feel of carbon yet the tight trajectory and stability of a steel shaft. Follow the jump below this image to read on and see it’s specs…
If you haven’t noticed Carbon Shafts have made huge leaps in terms of performance, feel and they rival the best steel shafts yet there is no widespread adoption of Carbon in irons and one of the biggest reasons is due to price. Often for high end carbon shaft’s they cost more and in some cases much more than a steel shaft Those of you who have tried the Roddio I-10’s or Fujikura MCI shafts know what sort of advantages carbon has.
Mitsubishi want’s to bring high modulus and higher tonnage materials to the masses with this shaft and the new OT Iron shaft comes in at an MSRP of under $100 dollars per shaft and they are hoping this get’s players to give it a try and once they do Mitsubishi is confident it will stick.
The OT Iron shaft is available in 2 weights 85g and 95g, Torque 3.0 mid kick. Do keep in mind that when using higher modulus carbon torque plays less of an effect because the heavier pressed tonnage carbon reduces shaft deformation extremely fast and in some cases even faster than steel.
The Above graphic sheds some light on why these shaft’s look to be a serious advancement in carbon shaft design. Normal carbon shafts are produced by rolling prepreg sheets and these sheets have been impregnated with resins by arranging the carbon fibers in a cylindrical shape. The OT iron shaft was made a bit differently by imersion of the resin into a bundle of carbon fibers “bundled” is the key here, then it’s braided ” braided”, this is not normal people in a very good way and it means stability while keeping feel.
The image showing shot dispersion is of the OT iron vs a popular light weight steel shaft in Japan, can we assume this is the NS950? Whatever it is this is a swing robot using the same #5 iron head at 39 ms and the latest Trackman then Mitsubishi took the average landing of 5 strokes on each club. To sum this all up they are saying the Braid and technology of the OT iron shaft feels better and is more accurate than steel.
This shaft will be released Feb/16th in Japan, stay tuned for more info @ TourSpecGolf
