So a couple of months ago, I bought a new front wheel from the local bike shop. It's a 28 spoke wheel, rims are the DT Swiss RR465 and the hub is a 240s.
I put 500-600 km on it and noticed a rattle after a ride. After isolating it to the wheel, I noticed that 3 of the spokes were extremely loose with one of them basically hanging. (The nipple/screw thing appears to be inside the rim somewhere.
Anyhow, I'm pretty sure I didn't hit anything and I'm not a terribly large guy. Are there things that can happen to new wheels/spokes, stretching or coming loose? Or is this a case of the LBS basically doing a crap job of building the wheel?
I'm nearly positive I didn't do anything wrong here, but I'd like to know if there was any possible user error.
