General on carbon bottle cages. Sizing and holding in place is no problem. But they tend to really tend to shift paint/resin on water bottles. At least on gravel bike. While on road bike the bottles stay mostly clean, on gravel bike is a no-go. If bopttles are not black, they look ugly as hell after few rides.
Does anybody have similar experiance on gravel bikes?
Would expensive carbon botle cage be any different?
