Review: 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 :)

## Questions & Answers

**Q: Can the faceplate be turned round ninety degrees? I have a Magene radar/light which uses the same quarter turn fit but is perpendicular to the Garmin.**
A: No it will not fit unless you buy an adapter like Wahoo ELEMNT Quarter Turn Mount Adapter from the likes of sigma sports £11

**Q: What's the distance between screw holes?**
A: It’s 20mm, well recommended

**Q: Can this be used on d-shape saddle post?**
A: If you mean the Giant D fuse then yes. There are a couple of rubber washers that come with it that enable a tight fit.

### ⭐⭐⭐⭐⭐ Quality product recommend.
*by P***. on 13 December 2025*

Quality product works as intended

### ⭐⭐⭐⭐ Bracket runs leg
*by C***N on 30 September 2024*

Good quality and comes with different sized shims and a spare screw. The bracket on the side with the screw does stick out a bit, and can catch the inside of your leg if mounted quite high on the seat post (which is where you would like your radar mount to be). The mount is now halfway down the seat post and the radar still works fine.
