The System CC tube is a special built large diameter thin wall thickness tube that is developed for a bigger sized tire but helps keep the weight down on the tube. In between the EX and the CC Lite, this tube works great.
The EX Medium weight tubes were tailor made for our EX line. The EX tubes have a thinner wall thickness that helps bring the weight down but still provides excellent flat protection.
The FRO heavy-duty downhill tubes offer maximum protection for the toughest conditions you will encounter. With 4 different sizes, you can get the correct size for your needs. Matched with FRO tires, you can't get much better downhill flat protection from a conventional tire and tube combo.
Each tube can save you over an ounce over a standard tube. The Race Lite Tubes are lighter than all other tubes, so this can be the least expensive way to loose weight off of your race bike.
