Hi Nick,
I bought one for my 520 and when i got the 690 it had one on it already. It’s the only damper i have used so nothing to compare it too. I think there is other brands that have a few more adjustments as TB mentioned but in the end it’s not something i play around with all the time while riding.
I have never had an issue with the one i had on the 520 but my current one on the 690 has an issue with the dial not reflecting what the dampening is. The only time i adjust it is high speed on the tar. I use it at max to take out any front wobble and then i back it off to around 3 for the trails. I usually don’t ride single trail so i find 3 is pretty good. I like it because it’s a under bar mount and is out of the way. I did however have dramas trying to find bar risers for it as nobody makes any.
Any other questions just let me know.
