The running distance is approximately 250km. ・No air unit punctures ・Used frequently in races ・Shows wear and tear, scuffs, and dirt from use ・Doesn't have the same level of responsiveness as when new, but still provides some rebound While past its peak performance, it's still perfectly usable for race training, speed training, and interval training. Please check the photos for the condition. Please purchase only if you understand that this is a used item with signs of wear. Instant purchase OK Please comment if you have any questions.
