Bontrager announced a major change to its warranty program for carbon wheels recently, upgrading the program to include a lifetime warranty against defect while keeping the Carbon Care Wheel Loyalty Program, which offers free replacement or repair of any Bontrager carbon wheels that sustain damage from riding within the first two years of ownership. This new lifetime warranty covers all Bontrager carbon wheels for road and mountain bikes and comes at no additional cost to the purchaser. It includes all Bontrager carbon wheels purchased aftermarket as well as those that come stock on Trek bikes. This program applies to the original owner only.
