Our lanyards keep you safe while riding, jumping fences, or leaning back. Compatible only with triggers from 2012 onwards, they provide strong safety and security, and an instruction manual is provided for easy installation and operation. With our upgrade program, you can equip your vest with the newest technology in triggers and maximize your safety. It is very important that you make regular checks for wear & tear on your lanyard and replace your lanyard every 2 years dependent on how long and how often you ride for. (not just on how many inflations it has had.)
