Well made and well worth it
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 :)

Very secure attachment for the Garmin radar
Fits my round saddle post & is a secure attachment for any Garmin or other quarter turn device.

Stabile e robusto
Ottimo prodotto, ne ho acquistato due per poter utilizzare il Garmin Varia su due differenti biciclette. Mi sembra decisamente meglio del supporto originale Garmin, sia come robustezza che come stabilità.

Ook goed voor Garmin Achterlicht op ovalen zadelpen
De originele Garmin houder werkt echt niet op een ovale zadelpen, deze wel!
