Building on last year's success with the popular Alien X, Rytera has introduced two new models to the line -- the Alien Nemesis and Alien Z. The three-bow series offers axle-to-axle lengths from 31 1/2-36 inches, brace heights from 6 1/2-7 inches and advertised IBO speeds that range from 330-340 fps. Unique riser design and an alien theme have set these bows apart from all others.
Rytera's Alien Nemesis displays intricate riser detail, is equipped with parallel limbs, adjustable Hybrix Duo Cams, Roto Cup Limb Control system, shelf guard and vibration dampeners on the riser and string.
The Nemesis riser serves as the backbone of the entire system by providing reflex performance, rear-strut strength, a base for other components and the bow's super stylish look. Like the Alien X, the Nemesis riser has a matrix of rounded bridges, sweeping radiuses and webbed connections. The Nemesis, however, has more intricate detail and sports a distinct rear strut. Promoting the Alien theme are two teardrop shapes that look like alien eyes cut into the riser behind the shelf area.
Functionally, the multi-part riser is CNC machined from a solid billet of aluminum and features reflex geometry for increased power stroke and speed. The rear strut increases the total depth of the bow (front to back), which adds rigidity and strength to the frame. Rytera battles vibration with an STS String Stopper that attaches to the riser opposite the stabilizer-mounting hole and meets the string with a rubber tip. An Omega Vibration Escape Module (VEM) fits into a circular receptacle just below the String Stopper mounting hole. The Nemesis grip is machined directly into the riser, complete with gently rounded corners that create a comfortable shooter-to-bow interface. Rytera offers the Nemesis in multiple finishes, including Next G1 Camo, Skulz Camo and four target colors. A series of green accents contributes to the bow's Alien quality.
Nemesis limbs are set at an angle that results in past-parallel position at full draw. Rytera creates consistency within the limb sets by matching each pair based on deflection values. This ensures each limb provides the same amount of power as its counterpart. Each limb measures 13 inches long, is straight in form (not recurve) and solid in construction (not split/quad limb sets). Rytera limbs are also unique in that they offer 15 pounds of adjustment. Limb sets are available in ranges of 35-50, 45-60 and 55-70 pounds.
The Nemesis is advertised to reach an IBO speed of 335 fps, which, in my opinion, puts it in the speed bow category. It wasn't all that long ago that anything over 330 fps was extremely rare. When purchasing a Nemesis, you can choose either the Tranz Single Cam System or Hybrix Hybrid (dual cam) Cam System. The test bow was rigged with the Hybrix. Hybrix 1.5 and 2.0 models cover a draw-length range from 25-30 inches, in half-inch increments. System letoff is 85 percent maximum, with infinite downward adjustment through a movable draw stop. Both hybrid cams ride on flanged speed bearings and precision, stainless steel, heat-treated axles for decreased friction and increased efficiency. The track around the cam hub has a helical cut, which forces the cam to stay properly aligned from the at-rest position to full draw, thereby reducing torque.
At the range, only a small, short-lived bump was noted in the handle at the shot, with some leftover vibration continuing beyond that. The draw cycle was aggressive, but it demonstrated smooth transitions and a comfortable overall feel. The grip is well formed, comfortable and functional in that it allowed my hand to seat repeatedly in the same position shot after shot. Most impressive of all was the superior balance of the Nemesis -- it was rock solid on the bull's-eye.
