skewers: a universal fit?

I have a mid/early 90's specialized hard rock that I use for just about everything but mostly just riding around. Yesterday, after changing a flat tire i was retightening the rear wheel and closing the clasp on the skewer when the skewer rod broke...about 1/8th of the way down the rod. So i'm going to pick one up today, and just want to see if they are universal. Any help? Thanks!

The skewer diameter is universal but the rod length will vary. Front wheel skewers are sized for a 100 mm OLD hub plus dropout thickness and aren't long enough for rear wheel use.

Rear wheel skewers are currently made for 130 mm (road) or 135 mm (MTB) hubs but the MTB skewers are usually threaded far enough down to fit both hub widths. You probably need a skewer long enough for 135 mm dropout spacing.

Some MTBs were/are 130mm. Your hard rock is likely 135mm, but it doesn't hurt to measure it yourself: http://sheldonbrown.com/gloss_sp-ss.html#spacing .

By the mid-90's I expect 135 mm was almost universal. My '92 Trek 7000 is 135 mm.

As noted, most 135 mm skewers will tighten down to work on 130 mm hubs and, if needed, the excess rod can be sawed off and the end filed smooth.
