G5 quietly makes some of the world’s best hunting bows, with rigs such as the 2016 Rize leading the way. Prime’s flagship Rize features a new version of the signature Parallel Cam system, a riser made from a new aluminum alloy, low-profile Ghost Grip, Flexis-AR adjustable cable-containment system and more.
As you might expect from a Prime flagship bow, the Rize gets the job done with a Parallel Cam system that splits the string on each end and runs the individual legs on one of the tracks created by the dual cam lobes.
Essentially, this design creates side-by-side cams that offer a wider base and balance the load.
At the same time, the cables, which apply a generous portion of the load, can now be placed directly in the center of the system to further discourage efficiency- and accuracy-robbing cam lean. The machined aluminum cams ride on quick-pull axles and sealed ball bearings for reduced friction and increased efficiency.
What is different between the new PCXL cam and its predecessor (the PCX)? Simply, the new cam is now adjustable up to 85-percent letoff via adjustable limb stops.
It should be noted that to increase the letoff you will essentially lengthen the draw, which depending on your actual draw length and desired letoff may influence the base draw length cam you choose. Speaking of which, Prime Rize draw lengths are available from 26-30 inches in half-inch increments with a separate cam for each.
Strength of Platform
Prime aims to create super strong and stiff risers to serve as the platform for its bows. Why is that important? As defined by Prime, its stiffer risers result in better accuracy.
Now, we can debate the meaning of accuracy vs. precision vs. consistency vs. repeatability for an hour. However, it should suffice to say the implication is a more rigid platform benefits the shooter! Prime gets there with a new aluminum alloy called 82X.
Connected to the outside of the sight window, the Flexis-AR cable-containment system employs an adjustable position allowing the shooter to fine-tune the distance between the cables and the arrow. When the bow is drawn, the Flexis moves toward the centerline of the overall rig and reduces torque. However, when the arrow is released, the limb-like material springs into action and moves the cables clear of passing vanes. Double rollers and a weighted vibration-dampening device complete the Flexis system.
Two flexible side plates are seated in recessed pockets on the handle to create a flush grip held in place with hard plastic tabs locking into grooves. The Ghost Grip, which is said to position the wrist neutrally, can be removed without tools and replaced with Prime’s Ultra Fit Grip.
All That Remains
Limbs, limb pockets, string/cables, a string dampener and a metal stabilizer insert round out the Rize bow. Limbs are solid (not split), measure 13″ long and reach a past-parallel position at full draw to help reduce shock, vibration and noise.
The machined aluminum pockets pivot during the weight adjustment process and have locking screws to anchor their position. Prime uses BCY 452X for its string and cables.
The Prime Rize is a very good all-around bow with an extremely dead-in hand shooting experience. Only a very small kick can be felt at the shot, with no perceptible follow-on vibration.
As a result, this rig produced a super-quiet shot. The draw cycle was smooth throughout, with no noticeable hiccups along the way.
Although it may prove a little chilly in cold weather, I like the Ghost Grip, which is made mostly of the riser handle material with the addition of two small side plates.
