Rated 5 out of 5 by from consistant performer I have used the 65 'competition' series for several years repairing clubs for my fellow golfers and have always had very good results and compliments on their performance. Recently, a friend asked to have his steel shafted Callaway irons replaced with the Competition 65 shaft to swing between regular and senior. I accomplished this by down-stepping the 'regular', and it fits his desires perfectly.

Is it possible to make the tip .355 taper ? I am looking for a good graphite shaft to replace steel shafts in Titleist AP1 714 irons (4-9,P,W, - 8 shafts). If not, could you recommend reg. flex graphite w/ .355 taper tip to use in this application ?

Asked by: JoePuck
We could special order the Competition Series Graphite shafts from UST with a .355" taper tip to fit the AP1 irons. You would need to contact our Customer Service at or by calling 1-800-848-8358 and they can help you with the special order. Another shaft I would recommend that will fit the AP1 irons is the Xcaliber (AS0028) which is available in a .355" taper tip. It is a very good inexpensive shaft.

What does the "R/S" stand for? Is the shaft ready to be installed gripped and brought to the course? Or are there any other parts I need?

Asked by: Chris
R/S means it is a combination flex shaft that can be made to either an R flex or an S flex by following the shaft trimming instructions. We do offer a Shaft Prep service where we will cut the shaft for the flex that you want. We can also install the grips if you would like. It might be worth a call to our Customer Service Department and let them help you with your questions and your order. 1-800-848-8358

Do you cut the butt or tip cut the UST iron shafts?

Asked by: Chip
With the US0045 iron shafts you will cut both the tip and butt. You will cut the tip to create the flex for each club number and cut the butt end for the finished length you want the clubs to be.
