The K-Edge Adjustable Stem Mount for Wahoo Computers caters to road cyclists and trail riders seeking a stem-mounted solution for their Wahoo cycling computer. Choose this adjustable stem mount for your Wahoo Elemnt (original), Bolt, and Mini head units. The Stem Mount replaces your standard 5-millimeter spacer and locks securely in place by the top cap's force. It's only compatible with a 1 - 1/8-inch steerer tube diameter. K-Edge recommends running it with a stem rise of zero to negative degrees.
