I have noticed this odd noise when pedaling in the lowest gear at a low cadence. I thought it was chain rub, but today I was oiling my chain when I noticed that my rear wheel seem out of true. I have never trued a wheel, but I spun it near the brakes a few times and grabbed a spoke, it was lose. Very little tension.
I tightened it and then trued it by bringing the brakes closer and closer. It seems true, but some of the spokes are still somewhat lose (like two and just not really high tension). They are tighter then they were, but still not immovable like the other spokes. Is that normal, or have I done something wrong.
Wanted to go on a ride today, but am not sure it is safe now. What do you think?
Also, could this (lose spokes) have been the noise I was hearing?
