For modellers wanting precise ratio adjustments, the XRAY 385702 Composite Pinion Gear Set provides a compact solution. The pack contains four moulded gears with 9T, 10T, 11T and 12T tooth counts to suit varied setups.
These pinions use a quality composite to deliver predictable tooth engagement and resist premature wear. The moulded finish helps maintain consistent mesh across repeated runs.
From 9T to 12T you can balance top speed against torque to match track layout or surface type. Changing pinions is a simple way to tweak acceleration and top speed for specific sessions.
