Replacement Wind Cups & Axle
Maintenance-free, quiet and high-performance. Machined to extreme levels of precision; the tolerance is just 0.001 inch, for smooth, silent rotation in even the lightest air movement. The cups include a tiny magnet in the flange at the base for wind speed, and a brass jewel bearing in the top.
