I'm pretty new to biking and don't know much about repairs (yet). I tried Googling this one, but there seems to be no easy way to tell what size nipples (my rims) have.
Apparently I like going off curbs, as today was the second wheel true I had in less than 40 miles, so I'm thinking of getting a spoke wrench so I can do it myself. These are the rims I have:
Is it even worth buying a spoke wrench or can I just use needle-nose pliers?
