Here is my situation:
-Broke a spoke three weeks ago. Rear wheel, right side. Replace, trued, back riding.

- Broke a spoke yesterday. Rear wheel, left side.

After going through the hassle of replacing one spoke only to have another break, I'm going to replace all of the spokes on the rear wheel.

My question - a mechanic suggested it might be a hub issue as well. Anyone think this could be true? Or, was he just being precautionary?

The spokes broke on different sides and different places (one at the hub flange, one 4" from the flange, where the spoke tapered)

Specifics: wheel is 5 years old, Formula track hub, DT spokes, Mavic cxp-22 rim. I replaced the cartridge bearings last year, but no other issues. Have around 9000 miles on this wheel.

As I said, I'm going to replace all the spokes and I am also going to move up to a nicer Mavic rim. I was going to reuse the hubs, but now am wondering if I should get a new hub. This is not a race wheelset, and Formula hubs are certainly of good quality. I'd rather not spend too much on this project. I wouldn't want to just sidestep and get another set of Formulas/equal quality...but jumping up to something nicer (Dura Ace, etc) would really push up the costs.
