Pro Bike Holder is Cellularline’s strong and resistant handlebar holder that’s compatible with smartphones measuring 4 to 6.5 inches. Fitted with an adjustable clamp, Pro Bike Holder can be installed on handlebars from 2 to 3 cm in diameter. The holder’s base rotates 360°, while it can be released from the clamp and removed from the handlebars, so you can stow it away when it’s not in use. To provide your smartphone with the best protection, Pro Bike Holder is also covered with soft, scratchproof silicone.
