I am trying to work on endurance in the hopes of one day touring the GDMBR in a reasonable amount of time and after watching Ride the Divide, I noticed a lot of the riders are using aerobars. When I am training, I can ride close to 40 miles on my bike with a Specialized flat bar but I am noticing significant pain in my back, tailbone, wrists and shoulders.
Are aerobars the answer to my pain problems? My assumption (from purely a comfort viewpoint) is that aerobars allow you to shift your weight occasionally and distribute your weight differently without stopping. If so, is there a certain type of handlebar I should be looking at for a mountain bike? I would prefer an easy to install/uninstall solution because I am not always looking to have these handlebars on. Also, is adding an aerobar the proper solution or am I looking at it wrong? I am questioning bikes at the moment and would be grateful on any tips.
I have never used any other type of handlebar other than a flat bar, so please include anything that may seem incredibly obvious.
Note: I looked at this answer but those look incredibly uncomfortable for long distances and seem pointless for what I am doing.
