I recently picked up Pivot Mach 6 (2019 model) and realised the DW link is basically a little rock grinder. Not the best for a carbon frame!
The online Pivot store in the States sells a protector for the lower linkage, which isn't available in New Zealand where I live, and I'm guessing many other countries. I also noticed there's no protector for the top linkage.
I've created DW link protectors for both the top and bottom linkages. You can make them yourself out of an old inner tube and some glue / high strength tape. I've also made a rear mud guard, but I'm yet to digitise that. I might get around to that in the future if there's demand.
In terms of compatibility, these templates work for the 2019 model Mach 6, although they might also work for other frames in the lineup with a DW link. Try them out and let me know!
