Review: I lost my Garmin Varia RTL515 rear light/radar to a 3D printed mount that failed mid-ride and I didn't realise until I was nearly home. I should have used a simple lanyard to attach the light to my seatpost, but these Tusita mounts are so well made and such good value that I got one for both my bikes, replacing the Garmin rubber band mounts, which always felt wobbly. The construction is top notch and they come with a range of spacers for different diameter seatposts. The bracket is hinged on one side and uses an Allen bolt (key included) to secure it. Mounting a light feels so positive and can be done one-handed, whereas with rubberband mounts, I found I had to hold the mount to prevent it from turning as I inserted or removed the light. I highly recommend the Tusita seatpost mount. Five stars...well, ten if you count both mounts :)
Review: Fits my round saddle post & is a secure attachment for any Garmin or other quarter turn device.
