Carbon is incredibly strong and more than suitable for carrying heavy loads over rough terrain. A high-quality carbon gravel bike or MTB makes for some of the best bikepacking bikes, the only issue being that if you damage the frame, it’s difficult and expensive to fix. If you’re stuck out in a remote area of a foreign country, you may have to ship the bike abroad to get repaired. Every bike has a load limit, so if you do plan to bikepack with a carbon frame. check the manufacturer’s guide before adding extra weight to it. Carbon bikes also have fewer mount points than aluminum or steel-framed bikes as these weaken the frame.
