Prometheus EG Hard Gear 13:1

The Prometheus EG Hard Gear 13:1 is specifically developed for high-speed setups and this gearset is 1 of the most reliable and strongest available.

The quality in this gearset is determined by extremely strong forged steel in Japan. This set is designed and manufactured with such precision that it has become one of the quietest gearsets, even at high FPS (Feet Per Second) and ROF (Rate of Fire).
Tested by Prometheus on an 11.1v 20c lipo battery with a high-torque 40k motor and on an MS135 spring (400+ FPS), the EG Hard Gear set withstood more than 10,000 rounds of continuous use with no visible wear.
