Do I need new spokes?
So I was riding on a set of wheels that I bought off of CL a couple days ago and broke a spoke. My fault, the wheel is probably 20 years old and the spokes were not at tension. So I bought a new spoke and took the opportunity to de and re-tension the wheel and true it all up. However, when I had it just about up to tension, another spoke broke. Both spokes broke right at the head. I do not have a tensionometer but I sure didn't think that the wheel was at that high of tension and this type of thing has never happened to me before.
So the question is, do you guys think that all the spokes may have been damaged in the past and I am in need of a new set, or can I just replace this second spoke?
Thanks in advance for your replies.
