Ohlins Electronic Shock Rebuild ??

Seems to me that someone did a manual conversion for the Ohlins many years ago.
Possibly Bjowett, not sure. I know he used to sell replacement solenoids. Again, many years ago.

And BTW Hygear has always rebuilt my Ohlins (and other shocks) with a decent turnaround and pricing.
