This is a spare or service part rather than an assembled hub, so Chris King covers it against manufacturing defects rather than under the assembled-hub King Lifetime Warranty; Australian Consumer Law guarantees also apply. For warranty support, return the product to Tune Cycles and we'll manage the claim with Chris King's Australian distributor.
