DLC*1-coated Offset Support Arm
The Ultima Recurve Rest's Support Arm makes use of DLC-coating – a technology offering a good material strength and friction properties, applied in fields such as parts for racing engines. As a result, the energy loss inflicted on an arrow gliding over the arm is reduced to a minimum. The Support Arm's Offset construction guarantees no contact with the cushion plunger's barrel, even when used with the smallest diameter shafts.
*1: DLC (Diamond-like carbon): A coating of amorphous carbon, granting exceptional hardness, wear resistance, and slickness (low coefficient of friction).
Dual Adjust System for perfect clearance
The Ultima Recurve Rest is adjustable not only vertically, to ensure compatibility with any size arrow shaft, but also horizontally to compensate for sight window depth and plunger settings. There is no need to cut or bend the support arm again! Adjustments are easy to make with one screw, even when the arrow is rested on the support arm.
CNC*2 machined for unrivalled precision manufacturing
By employing CNC milling, Shibuya was able to reduce dimensional error margins to a minimum. The innovative "V-lock" Magnet configuration ensures smooth and repeatable movement.
*2: CNC (Computer Numerical Control): computerized automation of machine tools such as milling machines.
SHIBUYA's V-Lock System – unrivalled precision and repeatability
The line of magnetic force between the Ultima Recurve Rest's dual magnets catches and returns the Support Arm safely and repeatable, exponentially increasing the reliability of the rest. Shibuya uses only high quality corrosion-resistant samarium cobalt magnets, known for their constant magnetic force independent of temperature changes.
By placing the adjustment screw between the magnets, Shibuya was able to maintain a slim construction (only 3.8mm including adhesive tape), while at the same time using a 3mm screw for comfortable, safe adjustments.
Industrial-strength adhesive tape
For attachment to the bow riser, Shibuya is employing industrial-strength double-sided adhesive tape. The flexible, thick tape is ideal for ensuring a lasting and reliable bond.
Ultima Recurve Rest can be switched between RH and LH simply by reversing the support arm's fastening direction.
