Whatchamacollars are a new Xtracycle technology that serve three primary purposes:
1. They give you the flexibility to run one rack (V-rack or Adventure Rack) alone, without a snap deck, with no rattle.
2. They provide a theft deterrent, by making it challenging to disassemble the Xtracycle platform without tools.
3. Using an o-ring inside of the collar, they block water from penetrating into your Xtracycle or Big Dummy Uprights.
Whatchamacollars also may serve to increase pressure on Snap Decks that are not secured by the existing V-rack tension.
