Warranty replacements are the responsibility of the manufacturer. Full Tilt Bike Co cannot approve a warranty directly from any brand. It will be your job to contact the manufacturer of any other brand to get a claim processed. Warranty policies vary by manufacturer and only cover MFG defects. They do not include normal wear and tear, crash damage, or improper care. The manufacturer will instruct you on how to process any claim and we are not responsible for these items or their policies.
