Ohlins shock bumper 2011

[Neil E.]

I notice my shock bumper is a very loose fit on the shock rod (just had the unit serviced). Does anyone ever do anything to anchor the bumper at the bottom of the rod? I suppose the ID will just fill up with dirt and the bumper will stay in place.

I have a feeling that after a couple hard bottoming events the bumper will be inclined to star down - just go ride and tell us what you find.

Lift the bumper up and put a blob of RTV silicon on the base to hold it down.

I considered that, but it might be too much of a water trap if it's sealed off at the bottom only. Maybe filling the ID completely with silicone seal is better.

Not in the bore around the shaft, on the flat part of the base.
