why are some spokes longer than others??

some spokes are longer than others on my rear wheel, i am rebuilding it just to learn how to do it and kept coming up with some spokes bieng way tighter than others when i screw all the nipples down to the same spot for the base to tension them and i knew i laced it right so i started comparing spokes and some are about 1/8th longer than others, should i file them down to match with the others or should i use the longer ones on a certain hub or what?

If it's a rear wheel that your are building then the shorter spokes belong on the right(drive) side of the wheel.

The front wheel spokes are the usually the same size, if not, then get the proper size spokes.

Your 'geared' or drive side of the rear wheel uses shorter spokes because the hub flange is closer to center than the flange on the non-drive side. This is to accomodate the freewheel or cassette cluster. In other words, the rear wheel is dished. The non-drive side requires longer spokes because the flange is further out. Front wheel requires no dishing as everything is symetrical and centered. Hope this makes sense.

Yes, the REAR wheel spoke length difference makes sense.

Any idea as to why the front wheel of my set of Race Lites uses yet a *third* spoke length?? Why not use the same length as the longer of the rear spokes so you only need to keep two lengths on hand? (..and I'm sure the explaination has to do w/ weight )

Because that would be too easy.

I think that's just the way it works out. Front dropout spacing is only 100mm vs. 130 or 135mm for the rear. The front hub flange spacing just comes out where it does. I wouldn't worry too much about stocking spare spokes for the front. When's the last time you popped a front spoke?

Oops. Not one that I've done yet, but I've sure come close a couple of times. I also remember hanging around the parking lot at the end of a ride and finding a pretty darn nice front wheel just laying there. One of the other stragglers said he knew who it belonged to. I hope he wasn't lying to me.
