I bought an amazingly stylish VDO wireless computer from Mountain Equipment Coop, (http://www.mec.ca/Products/product_d...=1115079196555) and I took it back today after it insisted on telling me that I was going at 93 km/h. I know the new bike is fast, but that was more than a little silly. I suspect it was picking up interference from my BlackBerry, or from other people's cellphones, or from the power cables I rode under. I now have a much more basic CatEye Tomo from the LBS, which is much less beautiful. But it seemed to work just fine when I took the bike round the block this evening to check I had installed it right. Only thing I have not been able to work out is how to install the kms I had already done on the old computer onto the new one.
