Hop Up Thing - Fine Adjustment Ring

Fine Adjustment Ring

A drop-in replacement ring for the PolarStar V2 Hop Up Thing, designed for high-contact buckings like R-Hop, flat hop, and Maple Leaf-style buckings.

Larger contact patches make standard hop-up adjustment overly sensitive — small movements create big changes. The Fine Adjustment Ring doubles the adjustment sensitivity and shifts the window slightly downward, giving you precise, repeatable control where the standard ring can feel twitchy.

If you're running an R-Hop or flat hop setup, this is how you actually dial it in.

Compatible with the PolarStar V2 Hop Up Thing only.
