Serpent 977 low-friction pulley set
Serpent have introduced a low-friction belt pulley set for the 977 1/8th on-road car. Made using a new composite material that creates a super-smooth surface the pulleys make for a more efficient drivetrain and thus overall improved performance. Due to the material being a bit softer than the standard black parts the wear rate is slightly increased. Included in the set come all needed front, side and rear pulleys.
