Cycle computer wire broke - can it be fixed?

how did you splice them together?

Try stripping back about an inch and a half of insulation from each lead, then lay them parallel with 1/2" overlap  so that the wire continues in a straight line (not like you would if using a wire nut).  Make sense?  Put a long shrink wrap tube on one wire and slide it away from the cut so you have room to work.  Gently twist the two overlapping sections together just enough to hold them in one place.  Use a soldering gun (okay), soldering iron (better) or pencil torch (best) to heat the wires, then apply soldier to the joint, making sure it coats and infuses into the joint.  The final product shouldn't look like a gob of solder on it, but rather it should appear tinned.  Slip the shrink wrap tube over the bare wire and shrink with a heat gun, making sure not to melt anything.

That joint should be better then the origional wire, so if that doesn't fix it, then nothing will.

Yep, just replace the mounting unit. It's not a big deal. Cateye's run about 15-20 bucks for the mount. It's cheaper than a tire. I expect my wiring to go south once in a while. I have the same mounts on all my bikes and just move the computer between them. I use an Enduro which has two wheel diameter settings.

The fact that these things are easy and cheap to replace (and interchangable) is why I use wired bike computers. I work with computers all day and expect them to break on occassion.

Wow, 2006 thread!  I'm guessing it's a 50-50 chance.  Try one way -- if it works, you're set.  If not, detach and try the other.

Also, if you're reading this thread at work, don't google images for Sigma 906.  You'll get a NSFW result not too far down the screen.
