Having driven over 400 miles back from Ullapool, with one front damper disconnected over every conceivable type of road and surface, what I do know now is that your choice of damper on a Trad, certainly at the front, will make little difference to how your Trad drives.

The single setting Spax on my 2016 Plus 4 were very good. I couldn't resist changing them for AVOs, but the difference really is marginal. Whether they are better is subjective, and what really is "better"?

Although I've ordered replacement parts for the AVO, I decided to fit some Spax gas adjustable on the front. Another probably futile experiment but we'll see.

The bottom mounting..the AVOs have two bushes with a steel tube inside. The fixing stub has a raised section beyond the threads, so I tighten the nylock until the penny washer seats on the raised section.
The Spax just have two bushes, without a steel insert

At the top, the AVOs have a dished washer, then a bush with a raised lip to locate in the hole in the bracket on the crosshead. Next another bush with a raised lip then a dished washer on top, plus nut.

The Spax have two smaller but thicker bushes, each has a dished washer both sides, and one of each washer is shaped to locate in the fixing hole. Interestingly the Spax have a nut and locknut, rather than a nylock. There is no metal sleeve in the bushes supplied.
I'll nip the nuts up until they look right and feel right on the spanner.

That's a long-winded way of saying it really won't make a lot of difference.

The Spax have 28 clicks, so I'm starting out at 12. See how we go.

Now I'm tempted to fit Spax adjustables to the rear........ grin2
