I was inspecting my bike and noticed that the rubber rings at the top of the rear tire shock absorber spring are split. I don't know how long these have been this way but and it doesn't appear to be hurting how the bike rides or handles.
Does anyone know what these are called or the part-number if I want to replace them? My keyword search internet kung-fu is failing me.
The bike has been kept up on maintenance with its most recent being last September 2019. They changed the rear-tire then and didn't say anything about the shocks or other systems on the bike needing repair.
It looks relatively harmless as these are just simple rubber rings and don't appear to be structural.
