Jacob ★★★★★ Oct 21, 2026

The double sockets fit my 2.25" ball bases snugly, and the single spring makes adjusting the arm angle quick and tool-free.

Victoria G. ★★★★★ Oct 18, 2026

The spring-loaded sockets snap onto those 1.5" balls with a satisfying click, and the jam nut keeps everything tight even after a week of rough trail rides. Pivoting is smooth but stays put when I need it to, which is exactly what I hoped for.

Samuel ★★★★☆ Oct 23, 2026

The jam nut design holds my ball mount securely without loosening over time, which is a nice improvement over cheaper arms I've used. The only minor complaint is that the spring feels a bit stiff at first, but it loosens up after a few adjustments.
