Maintenance Note: If your cable feels "stiff" rather than broken, try injecting some silicone or graphite lubricant into the cable housing. It can often save a cable that is just starting to bind.

Installation Tip: When routing the new cable, avoid tight kinks or sharp bends. The smoother the path from the lever to the latch, the longer the cable will last.

Pro Tip: Before tightening the cable at the latch, make sure the lever end is fully seated. A small amount of slack is necessary to prevent the seat from accidentally popping open while riding.
