Sometimes simple really is better. This is one of those times. The M2 Racer Wrap and Roll device is so simple that when it is lying on your desk as a pile of silicone stuff, you are hard pressed to figure out exactly what it is. But, stretch it over your handle bar and wrap it around using the little animation on the M2 Racer site, and suddenly it all makes sense, beautiful, simple, clear effective sense.
You can attach a very wide assortment of devices to your bar with absolutely no adjustment or fiddling. Merely stretch the wrap and roll around the device and settle it into position and pedal off. The non slip nature of the silicone of which it is made holds things in place securely yet to some degree appears to absorb shock.
During our test, I secured a camera, an iPod, a cell phone, and a gorilla. All of these were held reliably and they all withstood curb hops and vibration without loosening. I was shocked by how large and weighty an object could be supported. I'll allow the photos to speak for themselves, but this product is elegant in its simplicity, remarkable in its holding capacity, and relatively inexpensive.
Simple really is better.
