OOD Ghost Micro-Flywheels are low-profile micro-wheels designed by Luke. Featuring a 17.1mm diameter and a gentle 15.5mm concavity, these wheels are built for legacy flywheel mods and blasters where aesthetics might be a higher priority. Additionally, these wheels are precision machined from black acetal to ensure optimal balance. Compatible with most hobby-grade 130-sized motors, including Krakens.
