K-Edge’s Garmin Mount is designed to fit EDGE 520 25 20 and other compact Garmin cycling computers. CNC’d 6061 T6 Aluminum construction is lightweight and strong and a hinged clamp mechanism makes installation easy. The replaceable locking mechanism is secure and reliable thanks to an extensively tested copolymer insert that’s designed to breakaway in case of a crash instead of damaging the mounting points on the computer body.
