Sometimes when it gets HOT and HEAVY and you are delivering regular elephants each and every day, then the front headset can get loosey goosey. Normally it never happens. But this locking love-ring is for that time when it does.
ONLY for replacing the normal headset cap on an Integrated (newer models) front Omnium Cargo headset.
NOT for Omnium Mini-Max or Mini or another other damn thing.
