UST Competition 75 Golf Shaft Specifications

UST Mamiya Competition Graphite Iron Shaft is rated 5.0 out of 5 by 1.
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.

Need to replace nickent 3DX RC graphite SR 2.5 R flex 75 gram shaft. What low cost shaft do you recommend?

Asked by: Chet
For good inexpensive shafts the UST Competition Series 65, Grafalloy ProCustom (TT202214) and the new Aldalite (AL0061) could all be good choices.

tip trimming length for 65 series iron shaft i want to trim for stiff flex

Asked by: donny
Trim code for the US0045 R/S combination flex shaft is IR11 for the Stiff flex. IR11 trim code is: 2" tip trim for 3 iron, 2.5" for a 4 iron, 3" for a 5 iron, 3.5" for a 6 iron, 4" for the 7 iron, 4.5" for the 8 iron, and 5" for the 9, PW, 5" maximum tip trim. After tip trimming, trim to final playing length from the butt of the shaft.

Does the 73gm. rating apply to the stock shaft @42" prior to  the recommended IR3 > 7i. trim ? Additionally does a formula exist to predetermine net weight after tip & butt trim.

Asked by: Jim L
73 grams is the weight of the shaft before it is cut. What I do to calculate a cut weight is to divide the weight of the raw shaft by the raw length. In this case 73 divided by 42 equals 1.738. If I trim 2" off the shaft it I would multiply 1.738 by 40" and it equals 69.52 grams. This will generally be very close.
