This is because of the relatively large barrel on the shaft. These settings work fine for the shafts weaker than 650, but for stiffer shafts, less centershot is needed than for ordinary parallel shafts. What is the best centershot setting for the X10?Ī common error made by intermediate shooters using X10 shafts is that they apply “textbook” centershot settings to the X10. Better to use the correct size arrow, or slightly reduce bow weight Generally, up to one inch can shift the shaft an equivalent of halfway toward the next stiffer shaft size- however, this reduces the effective forgiveness feature of the shaft design, which is why it’s generally not recommended.
However, the exact answer to the effective amount of change varies by a number of variables, the biggest of which is the relative string amplitude at release of the archer – something no chart can account for completely. As the shaft is cut from the rear the “tail spine” of the shaft gets stiffer. This is because of the long taper on the rear of the shaft, and how the arrow reacts to “loading” on release.
What’s the effect of cutting an X10/ACE from the rear/How come there’s no chart to tell us the effect/Why doesn’t Easton recommend cutting these shafts from the back?Ĭutting X10 (or, to a somewhat lower degree, the ACE) shafts from the rear of the shaft results in an effectively stiffer arrow reaction, one that is disproportionate to cutting the same amount from the front of the shaft. Also, the cost to produce the X10 is considerably more due to the materials and techniques required to hit the required tolerances. For the same reason, removing points requires a little more care and time in order to avoid overheating. Another factor is that more care is needed when gluing components, which is also due to the small diameter. The main disadvantage of the X10 is the fact that smaller diameter arrows at higher momentum potentials require better target materials to help prevent excess penetration or pass through. Most importantly, the X10 has a high ballistic coefficient – it correctly balances mass weight and momentum for better performance from recurve bows at longer distances, especially in windy conditions. The X10 is also designed with three distinct, custom spine zones- and specifically, a less stiff and- importantly- lighter tail section, which improves clearance and finger release consistency, compared to the much stiffer and heavier tail sections of parallel shafts (or even so-called “tri-spine” shafts from other makers). There are several advantages- the smaller diameter of the X10 shaft presents less surface area and a smaller cross section, which is very helpful in windy conditions at longer distances. What advantage does the X10 have over other shafts? Are there any disadvantages?
