I bought a trek Fx 7.1 back in October since then I've had to have the wheel "rebuilt" because the ppl at the bike shop said the spokes were "like spagetti strings", went to get a tune up and they told me that spoke was broken and yesterday I had a flat and they told me that another spoke was broken. Please bear in mind that I wasn't riding in the winter. I live in NYC and some of the roads are crappy but for the most part I try and avoid pot holes and usually only carry gym stuff on the rack. Could this just be a bad wheel or am I doing something wrong?
