I find it a very useful skill; allows me to stretch my back, shoulders and neck on long rides, allows me to peel an orange or take the wrapper off a candy bar or energy bar while riding, allows me to move number 2 water bottle to the number 1 position when number 1 is empty without having to grip number one between my teeth, allows me to remove the windbreaker and put it in my pocket as the day warms up. Of course I could stop and get off the bike to do all these things but I enjoy the long nonstop miles in the saddle.
