Description
DLC※1 -coated Offset Support Arm
The Ultima Recurve Rest’s Support Arm makes use of DLC-coating – a technology offering superior 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 the bare 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
CNC※2 machined for unrivaled precision manufacturing
※2: CNC (Computer Numerical Control): computerized automation of machine tools such as milling machines.
SHIBUYA's V-Lock System – unrivaled precision and repeatability
The line of magnetic force between the Ultima Recurve Rest’s dual magnets catches and returns the Support Arm safely and repeatably, exponentially increasing the reliability of the rest. Shibuya uses only highest 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 super-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 from a trusted maker. The flexible, thick tape is ideal for ensuring a lasting and reliable bond. The hole is matched to major manufacturers’ plunger dimensions, which makes precise attachment easier than ever.
The “V-Lock” system, designed to achieve both slimness and functionality, features two magnets arranged in a V-shape, resulting in outstanding repeatability, as well as the ability to continuously adjust both horizontal and vertical arm position with a single hex wrench. For the support arm, we developed an offset shape to avoid clearance issues with the plunger. DLC coating, with its superior friction coefficient, supports the arrow shaft without causing excess energy loss upon the shot.
