NSR 7315 15-tooth low-friction plastic anglewinder pinions, 7.5 mm diameter, THREE per pack.

These are the tall-ratio end of NSR's 7.5 mm anglewinder plastic pinion range. The molded plastic construction runs quietly and with very little rotating mass, making it useful when you want a free-revving drivetrain and more straight-line speed.

Race use

• 15 teeth for taller gearing and higher potential top speed
• 7.5 mm diameter for NSR anglewinder gear systems
• Low rotating mass reduces drivetrain inertia
• Plastic-to-plastic mesh can be exceptionally smooth and quiet when set correctly

Pro tip: A 15T pinion is best where the motor has enough torque and the track rewards speed. Check mesh carefully—too tight creates heat and robs speed; too loose damages teeth.
