PDQ Developments in Slough talked me into buying a Nitron shock. Decided not to buy through them in the end, bought direct from Nitron and I fitted it myself.

They asked me a few questions, regarding my height and weight (single rider, luggage or pillion), then chose a shock for me. It was delivered ready to go.

Can't remember which model I have, but it's very similar to the Sachs shock, with only a ring to adjust preload.
