Frequent Questions & Answers
What is a pinion gear?
How do I choose a pinion size?
Go smaller for more acceleration and cooler running, larger for more top speed. Match the pitch to your spur gear and check temperatures.
What pitch pinion do I need?
Match the pinion pitch to your spur gear: 48dp, Mod 0.6 or Mod 1 are common. Mixing pitches will not mesh correctly.
