Is it possible to just buy a new rear wheel and move the existing one to the front ? Or does that have to be done in pairs?
My bike+rider+stuff weight is over 250#. I am using the Dura-Ace wheels that came with my women's bike. 7500 miles no spoke issues despite some crappy roads that will launch water bottles from the bike cages. I am careful to avoid potholes etc and to unweight when going over bumps. YMMV if you are strong enough to put more torque on the wheels with faster accelleration or higher overall speed.
