|Computer Mounts on 31 mm bars||Fini|

|This may have been talked about before, but I just purchased a new bike with the funky Cinelli bars that are 31 mm at the stem mount. My question is, has anyone tried mounting a computer to some of these bars..in particular a VDO?

|get one of those aerobar "knob" things (Profile, Sigma, etc)... a little knob mounts to stem, and you mount computer to this. All the major MO houses have these or your LBS should have/can order|

|I ran into this issue last weekend when I built my new bike. I went down to my local hardware store and bought a strip of stainless steel the approximate width of the computer mounting strap (and about .020" thick). I chose stainless steel for its' ability to resist corrosion (in a high sweat environment).
Next I fitted the computer mount to the bars and made a pattern out of heavy construction paper that accurately spanned the gap between the ends of the mount. The resulting pattern looked like a flat strip with 90 degree angles at each end. I then figured where to drill the holes. With the flattened pattern now placed over the stainless steel strip, I marked the bend locations and hole locations with a scribe and cut the piece to length. Stainless does not lend it self very well to drilling so be patient and use plenty of coolant (cutting oil) when creating the holes. With the piece in hand, use pliers to bend one of the ends into position (less than 90 degrees). Be sure to use your good eye when you guesstimate the angle, just go a little at a time until it looks right. Now bend the other end and deburr with a file. The really fun part is next: find something round and hard about the same diameter as your Deda handle bar (garden tool handles work great) and use this as a 'form' to press the bracket aginst. The bracket should be shaped to duplicate the curve of the bar.
This sounds like a lot of work but it actually took about 15 minutes (swearing time included).
I'll be fabricating another bracket for a friend who saw mine and has Deda bars. If anybody is interested I could work up a drawing (for you do-it-yourselfers) or build a few extra.
|how much is your time worth?||js|

|not much, apparently... those plastic things are lighter, and last time I checked plastic was corrosion resistant too|

|I used zip ties to attach my computer to my Deda Newton bar. The fix was fast, cheap and easy.|

|Transferring the Sigma 800 cyclocomputer from my ATB to my new road bike I found that I could not use the same zip locks because the handlebar diameter was a tad bigger on the road bike. So instead of the zip locks I used a two sided foam tape. The adhesive on the tape is like super glue but you can peel it off if need be. It works great but the Sigma has to held more firmly when switching functions as the tape has more play.|

|Thanks for the wisdom. I went to my LBS and picked up an aerobar computer mount. It was actually large enough to fir around my stem. At any rate, it worked out perfect. I think I like it better off the stem, than on the bars.
