  • Wilson CI7 Irons heads - question

    Hi All,

    Does anyone know whether the CI7 iron heads use taper shaft or parallel tip shafts? The Wilson spec page says they are .370 tip diameter and the UST shafts (proforce V2 Regular flex 74 grams) are custom to Wilson so I cannot determine from UST.

    Or do graphite shaft only come in either form (taper OR parallel).

    Also, as a related question the shaft torque is shown as 3.4 - this is much higher than that of an typical steel shaft - what are the real-world performance implications of such a large torque difference. as point of reference, I typically hit 5i 185-ish and 7 Iron is about 155-ish. I like the softer "feel" of the graphite shafts but am considering moving back to steel if the use of graphite is counter-productive in terms of dispersion etc.

    Thanks in advance.

    Regards, Chris

    http://www.golfworks.com/article.asp_Q_ai_E_376 - You can find all sorts of info in the GW OEM shaft replacement guide. Not 100% sure, but I'd guess they are 0.37, since their 2006 Di7 distance irons show they use UST Proforce V2 77 gm shafts.

    Or do graphite shaft only come in either form (taper OR parallel). I would say they vary and depend on the manufacturer, but I would guess that most OEM built taper tip heads for ease of fast club construction.

    Also, as a related question the shaft torque is shown as 3.4 - this is much higher than that of an typical steel shaft - what are the real-world performance implications of such a large torque difference. as point of reference, I typically hit 5i 185-ish and 7 Iron is about 155-ish. I like the softer "feel" of the graphite shafts but am considering moving back to steel if the use of graphite is counter-productive in terms of dispersion etc. I think the quality of graphite manufacturing has advanced enough today that you can get similar performing shafts, in either graphite or steel. Graphite also comes in weights much higher than lightweight steel. Also, you can find lower torque numbers on graphite as well.

    For instance, take a look the Tour Trac series at skfiber.com. They are a well produced, consistent shaft manufacturer.

    Thanks in advance.

    Good luck with your search...

      Thanks Torairder,

      I had seen that golfworks OEM guide before - it lists neither the CI7 or the predecessor CI6 and for those using the same (or looks to be the same) graphite shaft (UST Proforce V2), the taper vs. parallel question is not answered. Thanks for the reply - the search for information continues.

      I guess I could just remove one of my shafts, but since this is a new thing for me, I am not that keen on doing this just yet.

      Regards, Chris

          Beeker has given me the local Belleville phone number so I will call instead.

          Thanks for your reply.
