Calculating The Correct Axle Measurements

As a result of viewing the video above, calculate the face to face measurement.

1. Measure the offset wheel. The wheel offset is the distance between the inside of the hub and the outside of the rubber.
2. Add 50 mm to the offset. Alternatively, choose your own distance between the rubber and the chassis.
3. Multiply by 2 for both sides. Add your chassis width to the above number.

Still unsure of what measurements to take? Check out this handy guide below:

[P] - Check material specifications. What size and profile is the axle (for example, 45mm Square)
[T] - Overall axle length (tip to tip)
[F] - Hub face to hub face measurement
[A] - Chassis width
[C] - Tyre clearance
[B] - Back offset
[H] - Tyre to chassis
[G] - Axle pad centres

Identifying Bearing Combinations

You will also need to identify your bearing combination which can be done by pulling off a hub and bearings, and locating the number laser engraved onto the bearing. You will require both the inner and the outer bearing number.

Understanding the Calculation

The Face to Face measurements to calculate Tip to Tip measurement is as follows

• S/L 150mm Lazy add 100mm
• S/L 10” Electric Drum add 103mm
• 2T 205mm Lazy add 172mm
• 10” Disk Rotor add 98mm

How to calculate Face to Face measurement on your axle. Measure the wheel offset. (see video above)

The offset is the distance between the inside of the hub on the rim and the outside of the rubber. Add 25mm or the distance between the rubber and the chassis. Multiply by 2 for two sides and then add your chassis width.

Axle Flex

A wide 50mm square brakes axle assembly is your solution to axle flex from smaller axles.

Axle Flex will rapidly wear your springs due to the reverberation of vibration from the center of the axle back to the spring.

Effectively, your spring is working twice as hard as it should. Read our article about vibration fatigue.
