So for the record, I'm in the no bar bag camp, but the aero argument won't hold in this sub forum since the bag is used in training. Like I don't care how fast I'm going in training, I ride a TCR with box rims, butyl tubes and a lightweight non aero helmet. Training is for building fitness. When I race I care about aero - speed/skinsuit, Venge, aero road helmet, fast wheels/tires etc
