I had A-20s installed at Traxxion and have since put on a few hundred miles. Outstanding! Tracks so much better over the sometimes rough two lane north Georgia roads I usually ride. I also took it out on the Interstate this morning and it feels so much more solid (planted?) than before. It's hard to verbalize.
Wednesday I'll be up in the North Carolina and Tennessee mountains and expect I'll be delighted with how the bike (04DL650) handles.
The only potential problem I see is the temptation to fiddle with all the now possible adjustments, damp, rebound,and preload. Traxxion set it up for my weight and riding style and it seems fine, but you know, just like Madstad,
there's always "let's try a little more/less of this or that".
For now I really like it just the way it's set up.
