I had a rear wheel 2014 Reynolds Attack rebuilt about a month ago at a reputable shop nearby that specializes in servicing (they don't sell bikes etc). Some of the nipples were corroding hence the rebuild... I haven't ridden it much since the rebuild but noticed a few days ago it had gone out of true. When I took a look at it, I saw some bulging around the spoke holes in the area it had gone out of true. Strange that some are on the non-drive side but I'm guessing it's toast. Was wondering if this could be the result of something during a ride or whether the rebuild either used the wrong materials or wrong tension. Wanted some opinions of various scenarios before I take it back to the shop. What failure modes are there for carbon rims around spoke holes other than spoke tension etc.?
