Bearing Spacers ?

Hi can anyone help me ? I am replacing the bearings on my 36" Oracle and i am unsure if there is supposed to be a spacer on both sides of the bearing or just on the crank side?
Thanks in advance
Phil

It may vary depending exactly what axle. I’d replace what was there originally.

This is what was on my Nimbus 36er with an aluminum hub:

Bearing spacers

Hi Jim thanks for the reply i have a different hub than that, but i called Roger at UDC and he said that my hub only has a Spacer on the crank side.

Do a dry fit and measure before installing the wheel. For a 36" Oracle the bearings should be 125mm centre to centre.
