Rear Armstrong Red 620 dampers

[JasonJ]

Gents,

I’m overhauling the rear suspension on my +2 due to it having old repaired calliper fixing points on both side from possible Rotoflex failure, I was alway unhappy with these repairs, so i managed to source hubs with adjustable threaded( Elantrkbits damper tubes)

Since I have taken the dampers out that I believe were only fitted 3 years ago with new old stock Armstrong Red 620 dampers.

1 damper seems to be leaking ever so slightly and producing air bubbles ( please see pic attached)

My question is since I’m in the position to fit new dampers should leave out the newish old stock and fit new, which I’m pretty sure I will.

Can anyone suggest which damper would go well with this Elantrikbit conversion running with standard springs, my plan was only to adjust spring marginally tighter.

Any advice welcome.

Regards
Jason
