How long do cyclocross bikes last?

With proper maintenance, a CX frame can last 5–10+ years. However, CX racing is hard on equipment — drivetrain components may need replacement every 1–2 race seasons, brake pads every few months during race season, and cables/housing annually. Frames can develop cracks from crashes, barrier impacts, and the cumulative stress of off-road racing. Carbon frames are surprisingly durable but should be inspected after significant crashes. The overall lifespan depends heavily on how often you race in muddy conditions and how diligently you clean and maintain the bike after each ride.
