Wheel Build Spoke length info?

I recently had to change frames from a 7sp to a 9sp and I bought a new
rear wheel for it when I got the new frame. I am wanting to build a
backup 700c wheel for it. I have a velocity arrowhead rim that was
built on a 7sp 105 hub that was the backup for my 7sp frame. Its
rarely been used. Would those spokes work if I got a 9sp hub for it or
is the width change actually in the hub body? If not, where can I find
the spoke length I would need for the drive/non-drive sides of the
wheel.

I recently built a front wheel OPEN4/105 hub and with my dishing tool
and truing stand it is working great so I feel pretty good about
trying a rear wheel build.

thanks in advance

Download spocalc, an Excel spreadsheet:

Try Damon Rinard's spocalc program. Just google Damon Rinard and you
will find it easily.

Just put an 8sp hub body, which is wider, on your existing 7sp 105
hub. Leave about 2.5 mm of axel sticking out on the cassette side.
Remove 2 mm of spacers on the non drive side. Redish the wheel. It
will be pretty close if you turn each of the non drive side spokes ½
turn. Check to see that the tension on the drive side has not gotten
too high. Put on the 9sp cassette and go riding. Keep the 9sp hub on
the shelf.

Sure, they would be fine. The differences in hub center to flange for 7s and 9s
are small-

Good for you, it's how we all started, one wheel at a time-
