As bikes go, a stock Disc Trucker is not light weight at about 28 lbs. Obviously, this frame is not designed to win races. On the other hand, it is known for being a sure-footed bike, designed for rider comfort, that can carry a load and has the stopping power of disc brakes.
I am not a bicycle weight weenie. In fact, I believe that it would be a better investment in time, effort and money to lose a few extra pounds of body fat than pay to shave weight off a bicycle.
I just hope I am strong enough to pedal the beast.
