Consider shaft flex (the amount of bend in a shaft) when you shop. Beginners will want more flex than experienced golfers
Uniflex is a firmish-R flex shaft (usually made by True Temper). Not as stiff as a stiff-flex steel shaft from True Temper. But stiffer than an R flex True Temper shaft.
A Uniflex is a flex between regular and stiff, a bit more on the stiff side.
True Temper sells a uniflex steel shaft. This flex is soft, like a regular shaft but is supposed to be as stable as a stiff shaft and helps to increase the trajectory of the ball. Callaway and Nike have options for purchasing clubs with True Temper Uniflex Shafts.
Soft regular shafts are slightly lighter, and for people with a slower swing speed than those who use regular shafts.
Crank shafts make the ball lower a different center of gravity, it sits lower in the pocket. People say it easier to craddle and throwing is smoother
True Temper makes their steel shafts now, called Uniflex. Previously they were made by Royal Precision and were called Constant Weight Series. One shaft is stepped and the other stepless.
The easiest way to describe it is that the regular shaft is more flexible than the stiff one. The stiffer the shaft the quicker the swing speed needs to be to get the best from it. Also, stiffer shafts allow the ball to be hit farther, which is an exciting prospect for many amateurs but if someone with a slower swing hits a stiff shaft they will always hit low blocks instead of a nice high straight shot which they could with a regular.
Graphite shafts transmit fewer vibrations up the shaft to the golfer's hands than do steel shafts. This might be good or bad, depending on your skill and your desire. You might want that added feedback that steel shafts offer - or you might be tired of your hands stinging so much on mis-hit shots. The biggest and by far most important difference between steel and graphite shafts is this: graphite shafts are lighter than steel shafts. So clubs that have graphite shafts will be lighter than otherwise identical clubs that have steel shafts. The difference in weight between graphite shafts and steel shafts will translate, for most golfers, into an additional 2-4 mph of swing speed with graphite. And that could mean an extra 6-12 yards of distance with a graphite shaft, compared to a steel shaft. Steel shafts are less expensive than graphite, so the same set of clubs will cost less with steel shafts than with graphite shafts. Steel shafts were once considered much more durable than graphite. That's not s
One has a longer stroke than the other.Crank shafts ,and rod lenghts,the only difference that I know of.Same block,ect .
Eccentric shafts provide more strength and the support bearings are placed closer to driving points compared to crankshafts.
car/truck and marine Clockwise and counterclockwise rotations require different cam shafts.
nothing
Hey The difference between the two is the flex point of the shaft. The Rife shafts generally are for better golfers. The rifles have mid to mid-high flex points. Shafts like True Temper have all the points(low, med, high). The Rifle shafts are more personalised where as the others cover a larger range of golfers needs. In my oppinion, unless you are seriousey crazy about golf, save a little money and stay with True Temper. They make great shafts and there isn't that much of a difference to lower scores considerably. Rifle shafts are simply a brand, that's it. You have Ford and GM, each different, each just as good as the other, each has expensive models, each has chearer models. Rifle shafts come in all flexes and varying flex points, True Temper comes in all flexes and varying flex points. True temper shafts are what called a step steel, they have gradual steps in the shaft diameter as it goes up to the grip, rifle shafts have a smooth diameter change in the shaft as it goes up. True Temper calls there various flexes R, S, or X as in R-100, S-100, X-100, Rifle has there flexes as a numbered figure, such as; 5.0 (regular stiffness), 6.0 (stiff), or 7.0 (x-stiff).
no because some grips fit bigger shafts than others while others fit narrower shafts. This is the same with a putter, and woods.
