That's a common limitation. Litespeed, Trek and many others are very clear that their warranty obligation is to the original purchaser only. That's one reason to be certain you retain your sales receipt and, better yet, return the warranty card or register the purchase on-line.

Many years ago a friend bought a Litespeed from a dealer who promised to send in the registration card for him but never did and then went out of business. When the frame developed a minor crack 50,000 miles later, Litespeed refused to repair it under warranty since he didn't have a sales receipt, the bike was never registered and the dealer wasn't around to support his claim.
