Cracked rim .. whos to blame?
...putting on a new rear tire on my 2016 Masi, noticed the rim is cracked on most of the spokes on the chain side. Took it to the LBS where I bought it; they will get back to me, but probably new wheel w/existing cassette, which is in good shape. It has happened once before in my 25 yrs of riding as an adult, that was caused, I think, by riding over those 1" construction plates on the road. NP w/front rim. I weigh bout 175#. btw, this wheel broke a spoke several months ago. I got the bike Feb2016; has bout 6K miles. Tires are 38mm wide; bout 70psi. The spokes seem tight, but rear wheel spokes always seem tight to me. So, my ?s- How/why did this happen? How to prevent it from happening again? When ya buy a new bike, are the wheels shipped assembled, or does the LBS build them? I trust the guy @ my shop.
