Recommended sag at the shock is 13-15 mm. This equates to 27-30% sag. Note that because the link is more progressive it sags a larger percent at the wheel than it does at the shock. It is not advised to run more sag than this because the bike will sit in a region of its travel where anti-squat is lower. This link does not require excess amounts of sag to achieve small bump sensitivity. Please set your sag at around 14 mm at the shock and let the link do its work.
