I have a Talon hub in my extra rear wheel for the 690. I do not like the design of the rubbers exposed to dust and moist. You have to grease them but I like to keep them dry to prevent dust glue-ing to it and making sandpaper. I prefer the KTM design which is more like our Tenere hub.

I tried Tubeless but I do not like it. At home (sand mut but no stones) it works fine. But at rally speeds in Marocco both front and rear started leaking.
