Profile started producing 3-piece cranks right in 1979. Since their introduction, Profile has offered a “Limited Lifetime Warranty” to the original purchaser.
What does that mean?
If you buy a set of Profile Cranks, inside the box is a warranty card. Fill it out, get it back here to Profile and we’ll put it on file.
The warranty card will entitle the original purchaser to a lifetime warranty covering bending or breaking of either the crank arms or CrMo (steel) spindle (granted the damage has been done under normal riding conditions).
If you do not have a warranty card on file, your receipt can also be used for a proof-of-purchase, so it’s a good idea to save both the stub of your warranty card, as well as your receipt.
