I rent bikes most weeks so am constantly attaching and removing my Samsung phone holder from a rental bike, with different size handlebars and places to attach the bracket this has become a pain in the neck. Any suggestions on a phone holder that is very easy to attach and remove, or a dedicated GPS device that I can access ridewithgps that is also easy to attach? Currently, I use a Minoura iH-520-STD.
Thanks in advance.
