Drag Manual Primary Chain Adjuster
The 2006 and current bikes come with a automatic primary chain adjuster. It does a great job increasing tension as you bike chains age, but there is no reverse to loosen up if it over adjusts. That’s where the manual tensioners come in the clutch for easy fine tooth adjustments.
