ULTIMA RC PRO G2
features
The Pinnacle of Competitive Recurve Sights
For over two decades on the world stage, the ULTIMA RC has earned unwavering trust.
Now, with its innovative new polygonal extension and redesigned architecture, it advances even further—redefining rigidity, quietness, and balance. And with the finest micro-adjustment precision in SHIBUYA’s history, it brings out the highest performance in every shot.
Finer Adjustment — SHIBUYA’s Smallest Click Increment
Vertical and horizontal adjustments now move approximately 0.04 mm per click, an improvement from the previous model’s 0.05 mm.
This enables ultra-fine tuning to meet the micron-level precision demanded by competitive archers.
Zero Backlash — ZPE System Integration
The ZPE System, highly acclaimed in the CP PRO and CPX III series, is now adopted in the RC lineup as well.
By optimizing the internal structure, true zero backlash has been achieved.
Even during reverse adjustments, each click responds firmly, allowing for more accurate sight calibration.
Quick-Release Sight Pin Stopper
This allows smooth, one-touch adjustment and significantly reduces setup time—helping archers stay composed even under time pressure.
New Polygonal Extension — The Fusion of Balance and Silence
After more than 100 prototypes, the newly designed polygonal carbon extension has been perfected.
While maintaining the exceptional rigidity and vibration damping performance of previous models, it achieves an ideal weight balance and enhanced stability when mounted on the bow.
Every contour has been redesigned to guide each shot with greater quietness and precision, offering a seamless harmony of control and performance.
New Sight Mount — Precise Positioning with Click-Ball Mechanism
The newly engineered mount section incorporates a click-ball positioning system, allowing the extension’s front and rear position to be securely fixed with a tactile click.
This prevents alignment shifts during reassembly and enables quick, reliable adjustments with perfect repeatability.
As a result, both operational smoothness and consistency in competition settings have been greatly improved.

Product development
— Re-engineering a 20-Year Tradition —
While preserving the iconic X-Lock System that defines ULTIMA, we thoroughly reworked every area prone to play and wear over time—renewing maintainability, durability, and precision from the ground up.
To further enhance integration with the bow and optimize installed weight balance, we redesigned the polygonal extension cross-section from scratch.
Over 100 prototypes were tested. The result of this exhaustive exploration is an ideal balance that delivers exceptional stability and feel, while pushing rigidity, quietness, and vibration damping to the extreme.
It is the culmination of decades of craftsmanship—and relentless innovation.
