Secure your smartphone to your bicycle as you ride with the Universal Quick Plug Mobile Phone Clip for Bicycles from TELESIN. When used in conjunction with the Quick-Insertion Interface Fixture (required but not included), this clip will let you mount your phone on 0.67-1.38' diameter handlebars. Together they give you the ability to use a phone for GPS navigation or to play music as you ride. Two adjustable clamp arms with an anti-skid pad use highly elastic silicone straps to hold your phone securely in place at each corner. They can stretch to support phones from 3.5 to 6.5' in size.
