JimBob, It depends on the rod size. Naturally a 9 foot 2 piece would take a 4'7"+ long rod tube which would be difficult to secure to a mountain bike. I know a guy who uses his mt. bike to transport all his fishing gear, including a float tube, to a high mountain lake at the end of a 3 mile trail. He has added racks, saddle bags and other things to help him. He mostly pushes the bike. Also he uses a 5 piece travel rod in a tube that fits in a backpack. Jim
