10mm MBS Mountainboard Aluminum Wheel Bearing Spacers – 4 Pack
Wheel bearing spacers for MBS mountainboard rims using a 10mm axle.
These aluminum spacers install between the wheel bearings inside compatible MBS hubs. They help maintain the correct spacing between the bearings and allow the axle hardware to tighten without placing excessive side load on the bearing races.
Each spacer measures approximately 10.2mm inner diameter, 14mm outer diameter, and 22.4mm long.
Compatible MBS Hubs
Designed for use with compatible MBS mountainboard rims, including:
- MBS Rockstar Pro XL hubs
- MBS Rockstar Pro II hubs
- MBS Rockstar II hubs
- Other similar wheel hubs requiring the same spacer dimensions
Compatibility should be confirmed by measuring the original spacer or hub before ordering.

- Outer diameter: 14mm
- Length: 22.4mm
- Axle size: 10mm

What’s Included
- 4x = 10mm MBS mountainboard bearing spacers
Bearings, wheels, hubs, axles, and mounting hardware are not included.
Why Bearing Spacers Matter
A correctly sized bearing spacer supports the inner bearing races when the axle hardware is tightened.
Without the correct spacer, overtightening the axle nut may place side pressure on the bearings, causing:
- Restricted wheel rotation
- Premature bearing wear
- Increased friction
- Bearing damage
- Improper hub assembly
The spacer must match the axle diameter, bearing inner diameter, hub spacing, and overall required length.
Installation Notes
Install one spacer between the two bearings inside each compatible wheel hub.
Before installation:
- Confirm the spacer dimensions match your existing setup
- Inspect the bearings and hub for wear or damage
- Make sure the spacer sits between the inner bearing races
- Verify the wheel rotates freely after tightening the axle hardware
Do not use these spacers if your wheel hub requires different dimensions.
