A rebuild it is...
It's going to be one of those jobs to put on the back-burner, but I will get it done the next time I get the shock serviced.

Do you find that the sports riders (non offroad) who have Ohlins rear shocks get them serviced regularly (every couple of years or 40,000 km) or do they:
1. Not hold on to their bikes long enough
2. Think that an Ohlins on the rear says it all (and that's all you need to do)
