warranty card label
The space below is reserved for your bike's "Warranty Card." It is a peel-off label, attached to a hangtag on
every frame or frameset we ship (placed here by your Cannondale Dealer).
The "Warranty Card" includes a variety of printed product information numbers. The bike serial number is
one of them. You'll use the serial number when you register your warranty The serial number should match
the barcode label located on the underside of your bike's bottom bracket. The other numbers on the card can
be helpful later in the event of a product recall or other important safety information.
Please Note: The actual numbers printed on your warranty card may not be arranged in the format depicted
in the example.
