Prime Rival Review

April 21, 2015 By Jon E. Silks

The mission is clear, as stated on the company website, "Prime's mission is to build the most accurate bows on the planet.

Period."

And the path to get there is well defined — innovation and quality. That drive brought us Parallel Cam technology, which has enjoyed notable success and is the engine driving the new Rival.

In addition to the company's distinctive Parallel Cam technology, the Prime Rival features XS Extra Wide limbs, Flexis-AR cable-containment system, Side Panel Ghost grip and a reflex riser. On the silencing side, Prime includes a set of Limbsaver limb dampeners and an adjustable string suppressor.

Double Wide

Prime's PCXL Cam system is arguably the centerpiece of the Rival or any other bow in the Prime lineup. Using two matching lobes, basically two cams side-by-side, a wider base is created.

A yoke on both ends of the string splits the string in two, thereby applying the load to string tracks on the outside surfaces of the dual-lobe parallel cams. This is designed to increase lateral stabilization and reduce efficiency-robbing cam lean.

The machined aluminum cams ride on steel axles with Teflon bushings and roller bearings for reduced friction and increased efficiency. This cam produces an 85-percent letoff that is adjustable down to 75 percent.

Draw lengths are available from 26-30 inches, in half-inch increments. A separate cam is needed for each draw-length option. Limb stops on each cam can be adjusted to reduce the factory draw length by a half inch, which will decrease letoff percentage.

Center of Operations

Prime places a great deal of focus on creating a riser that's worthy to be the cornerstone of its new Rival. They start with a 7000 series aluminum forging, which is fully machined into the final riser shape. The manufacturing process is designed to create a strong and super straight riser that has very little flex. Less flex results in a stable platform and translates into operational consistency of the overall system.

The Flexis-AR consists of a roller-guard fixture attached to an arm that is both flexible and adjustable. Cables can be moved closer to or further away from the arrow/vanes using the arm's adjustment for optimal tune and clearance. Functionally, the arm flexes toward the arrow as the bow is drawn to reduce torque on the system.

Most of us want a quiet bow that doesn't rock our world every time we release the string. To that end, Prime has outfitted its new rig with accessories and technology designed to hush the shot. A Broadband Limbsaver dampener is attached to the inside of each limb. They are advertised to reduce vibration up to 70 percent across multiple frequencies.

An adjustable string suppressor is designed to quickly stop oscillation, which in turn reduces vibration and noise. Finally, the parallel position of the limbs is widely known to significantly reduce shock, vibration and noise as compared to a rig with upright limbs.

Impressions

I like where Prime is going with its bows. This year's ATA Show gave me the opportunity to shoot both the Rival and Ion side by side and both impressed me as solid, quality rigs that are smooth and fun to shoot.

The Rival's draw cycle is notably smooth, and there is little noise at the shot. A small kick and light, lasting vibration were both easily diminished with a quality stabilizer. However, this is a bow I would consider shooting without one.

I am a big fan of the Ghost grip as it excels in position, comfort and finish. The 4.3-pound mass weight is not unexpected in a 35-inch axle-to-axle bow.
