When I got a Scott Scale 925 mountain bike with a Fox 32 allround cross country suspension fork, I purchased the Brunox Deo for suspension forks to keep the fork seals protected and the workhorse suspension fork operating smoothly in the muddy winter season (in the Netherlands).
I’ve added a Fox Transfer Dropper Post to the bike set-up and keep the sliding post operating smoothly as well with Brunox Deo für die Federgabel.
