The K-Edge TT mount for Garmin offers a few advantages over the other products on the market. It is made well from alloy which perhaps adds a few grams over plastic but the difference is not significant. Unlike the normal riding position on the road bike where one has numerous hand positions on the bars and can move your head freely, when in the aero position on the TT bike vision is limited primarily to looking forward and a glance down at your head unit to see your metrics. The K-Edge mount also positions the head unit (computer) slightly below the upper plane of the aero bars which may slightly decrease wind drag. It took a few try to find the exact position that worked best for me while on the aero bars. Once that was established however it is second nature to glance down to see the display. Access to the side buttons on the Garmin Edge 520 is restricted compared to when the unit is mounted on my road bike but that too is a minor issue. Overall I find that the K-Edge mount is well suited for the intended application.
