I have been running some heavy tires for a while and I like them, but when I saw these Continental Mountain King 2.4's come into the shop I decided to try out a new set up. I was running Kenda Kinetics with a 2.6 in the front and a 2.35 in the rear. With the Mountain Kings I am going to try a 2.4 in front and a 2.2 in the rear. While I haven't been able to ride with these yet I can say that these tire dropped 3 lbs from the Marauder. When I combine this weight loss with the weight loss from the addition of Avid Elixer 3 brakes The bike has gone from 42.3 lbs to 37.1 lbs. If these tires hold up they will probably become a permant addition, if they don't I will go back to the Kendas. Look forward to a full review soon!
