BRAND TRIDOS DESIGN®
The CNC Hop-Up Arm for SSX23 and MK23 is designed to improve hop-up consistency and accuracy, especially when used with TDC adjustment systems.
Machined from a solid block of aluminum, it eliminates flex commonly found in molded components and provides more consistent pressure on the hop-up bucking.
Based on the well-known Hadron Designs H-Arm, this upgraded design introduces several refinements specifically developed for SSX23 and MK23 platforms.
The enlarged contact area and optimized geometry allow pressure to be distributed more evenly, improving backspin consistency and shot-to-shot performance.
Main features
