Stock wheels on a low end roadie won't last long. All salesmen will say it's good enough cuae he wants to make the sale. Best thing is to ride them till they fail (which won't be long if you ride alot) then invest ina good handbuilt rear wheel. The front usually lasts a bit longer.
Get a Deep V or similar 30 mm high rim cheap online. WHne the rear fails, have it built with the currnt 32 hole hub if you want to save money!
