spacer for JRA hubs – 1,2 and 3mm
£1.40
Spacer for all older JRA hubs. Newer free hubs since about 2019 use 2mm or 3mm spacers.
This spacer fits over the axle between the freehub and the main hub bearing.
The 1mm spacer fits older freehubs with an inner bearing which is not inset at all into the freehub.
The 2mm fits most current freehubs, where the inner bearing is inset 1mm into the free hub.
The 3mm spacer fits a few freehubs with the bearing inset 2mm, and has a circlip holding the bearing in.
In all cases, when the spacer is fitted to the free hub, it needs to extend 1mm outside.
