This Spacer is used for measuring the precise length of the spacer that each wheel suits, which could help to get the best spin.
How to measure the perfect length of each wheel:
-Place the disk under the meter, press and set the display readout to zero.
- press a bearing into the hub, and put the meter into another side, press it till the readout is stable.
- Choose spacers of proper lengths for your wheels. It's suggested to add 0.02~0.03mm to the readout.
- Use Rigour torque wrench with proper torque to fix the axles.
