Bow Review: Mathews Triax

Mathews is one of the most successful, technically advanced archery companies on the planet. If you want to feel good about your purchase, look online for the video Inside Mathews: A Manufacturing Powerhouse. The sheer volume of high-tech equipment is remarkable. That means one thing — we can expect the very best from Mathews every year.

At the base level, Mathews outfitted the Triax with a reflex configuration riser that is precision machined out of a forged aluminum block. The Triax is also home to what Mathews calls a dual-bridged riser, referring to the two flared sections — one above the sight window and one below the stabilizer mounting insert. The purpose of this design is to increase torsional stability in the platform, which is critical to system efficiency, consistency and performance.

Mathews TriaxCentral to the success of this riser is Mathews’ Enhanced Harmonic Stabilizer (EHS), a version of the harmonic dampeners the company has used on other rigs. Engineering and design time focused on reducing vibration/movement in all three axes from the grip. Mathews found that by maximizing the distance of the EHS from the grip in all three axes, they were able to achieve excellent results. The EHS is the only stabilizer on the bow and is located in front of and below the grip on a forward protruding tab machined into the riser. Testing conducted by Mathews found the Triax produced 78 percent less post-shot/residual vibration on average than the leading competitors.

Cam System

Mathews’ Crosscentric Cam maximizes both speed and a smooth draw in one package. Featuring AVS Technology, each cam is outfitted with two small discs mounted in an offset position on the axle. Both discs, which are used to anchor the end of each harness cable, rotate non-concentrically around the axle, shifting the force vector. This stores more energy on the front end of the draw cycle and increases letoff on the backside of the draw as the force swings to the other side. The other end of the cable is terminated on the opposite cam, forcing the system to work in harmony. The Triax offers draw lengths from 24 ½-30 ½ inches, in half-inch increments, and letoffs of 75 or 85 percent through a set of modules. Mathews uses its pre-conditioning Trophy Process to produce the Zebra Trophy X string and cables for the Triax.


Triax split limbs are notably short, wide and broad-based at just under three inches total width, which translates to increased torsional rigidity and a stable anchor platform. The position of these limbs at full draw plays a key role in reducing shock, vibration and noise. Wide-stance, closed-end limb pockets utilize a unique limb retention system to ensure perfect alignment at the critical interface between limbs and riser. Limbs are sorted into 50-, 60- or 70-pound sets using robotically controlled deflection force matching.

Supporting Cast

Cable management is handled by the Mathews Reverse Assist Roller Guard, which supports the cables on the opposite side of the rollers to create a smoother draw, reduce torque and increase overall efficiency. The Flatback grip has a prominent flat surface where it interfaces with the heel of the shooter’s hand and produces a level and low wrist position. Both walnut and carbon-fiber inlays are available for the Flatback. A Dead-End String Stop and Monkey Tails on the string work to quickly dampen string oscillation after the shot.

Range Performance

The Triax is especially impressive for its lack of shock, vibration and noise. The Triax barely moves in your hand during or after the shot and is also one of the quietest bows we have ever tested — very stealthy. Those who prefer a lightweight rig may consider the Triax a little heavy at 4.4 pounds. The Flatback grip performed well and actually felt better than expected in my hand. Last, but not least, is how this bow sits motionless at full draw. It does not fight you at all; it is a friendly aiming bow. One of Mathews’ best ever!
