xtr rebuildable?

Hey everyone. My question is that I have a xtr fh 950 rear hub and I want to build it back up, I bought it used and the guy I bought it from said he kept breaking spokes. After examining the hub it has some pretty worn spots where the spokes pull through(lines showing the direction the spoke was going, not big but still there). Is this hub still usable? I don't want to waste the money and the effort if I am going to be busting spokes constantly. Any info would be super helpful.

thanks,
joe

Broken spokes are ususally caused by defective spokes of bad wheelbuilding.

I agree.
More often then not it is because the wheel was not built properly. After that I would consider what type of spokes were being used.
My question is, where are the spokes breaking? By the hub, in the middle or at the rim?

It's normal (and desirable) for the hub flange to have grooves worn where the spokes have bedded into it (flange is aluminum, spokes are steel). As long as there are no cracks in the hub flange (very unlikely unless it was radial laced), it should be fine.

You should follow the existing pattern when lacing the hub up again. Most likely it was three cross but you should verify this.

Make sure that whoever builds the wheel is familiar with the idea of stress relieving so that your new wheel doesn't break spokes too.

thanks everyone for the info. Unfortunately I have no idea where the spokes were breaking. I bought the hubs used. The only one still laced up is the front. There are no cracks in the flange though so I guess it's time to build em up.

thanks again,

joe
