The Serpent 909245 25T pulley and integrated flange delivers tight tooth spacing and robust mounting for dependable drivetrain operation. It is a practical upgrade for vehicles that need consistent engagement under load.
The 25T design promotes even meshing and helps avoid jump or skip under sudden throttle. That stability benefits both straight line acceleration and technical sections.
Compatibility spans a wide range of hobby chassis when matching shaft and bore specs. Use it as a direct replacement or as part of a staged upgrade path to improve drivetrain response.
