Hmmm somebody should mention that to Lance... he's always wearing earbuds when he rides. I wonder if it helps him to pedal faster? I guess if one is riding in heavy traffic then it might be wise to pop out the earbuds or headphones until in a better place to be safe. That's a good point and I usually do that... but if there is a nice wide shoulder or bike path... I am all over the loud music... and hammering the pedals...
