Review on Docooler® Handlebar Extension Extender Speedometer by Bill Schlag

Originally wanted to return this product as many other people have stated it doesn't fit fully when installed, probably less than 1mm off. I used a washer on each side of the bracket and that fixed the problem. I put a loop of tape on the handlebars where the mount will be to keep it from slipping (and to keep the brace from scratching my bike), but it's not necessary. Other than that no problem, I've used this to center mount a flashlight on an electric bike (Sondors) and it turned out to be the perfect width to fit around the LCD screen mounts, perfect size for someone with Sondor.
