Mavic Askium front wheel bearings
I thought I would service the front wheel bearings this evening. When I removed the dust cover on the first bearing I saw a small plastic cover sitting on the bearings, I tried to remove it to get at the bearings, but it wouldn’t come out. So ended up pushing the grease passed it. The other side didn't have this additional plastic, it was what I expected to see once the dust cover was removed, full view of the bearings. So, what was this additional bit of plastic? Why was it only on one side?
