Lemme 'splain it to ya in simple terms,.............I cant trust a wireless,...alright???

seriously, I dont mean to be mean, but for some strange reason I've had nothing but problems with wireless computers, especially with Cateye. The first one I bought five years ago was a Cateye "Cordless". It never could give me a straight reading. Mileage varied as much as 4 miles on a measured course, and sometimes it would give me 55 mph speeds when I was going 20. Totally unreliable. I've had similar issues with VDO. Same thing, total unreliability, only this one would "zero" out for miles at a time every time a Fed-ex truck passed me. It was strange. Their so-called "digital transmission" was crap, so I sh't canned it and went back to wired.

The Blackburn 'Delphi 3.0' may be wired, but it's the coolest bike computer I ever used. It also has Blackburns lifetime warranty.
