TUSITASeat Post Quarter Turn Mount Compatible with Garmin Varia Rearview Bike Radar Tail Light RTL510 RTL515 RVR315 - Cycling 27.2mm 30.9mm 31.6mm bars Seatpost Mounts - Bicycle Road MTB Accessories

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 :)

Put this on my bike for the Garmin Varia radar, it is a secure and stable mount for it. It would only fit just about the rear wheel but that is due to the bike seat post being too large to mount it higher.

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.

I bought one of these for my road bike, thinking I'd just use the mount supplied with the Varia attached with rubber bands on my hybrid bike but it is so easy clipping the Varia on and off this mount with one hand compared to needing two hands on the supplied mount to stop it shifting. So I bought another 2!The rubber grommets supplied were enough to fit the seatposts on my current bikes, except the folder which has a 34.9mm post. So I keep the original mount for this bike.On the road bike I clamped it onto the seat tube so it didn't get in the way of the seat tube rack I was going to use. I

Having accidently snapped the rubber bands on my Garmin Varia Rear View Radar on numerous times by putting the OEM supplied bracket on my bike, I sought to find a more robust seat post mount for my device. The Tusita mount is ideal for my bike and gives me great confidence that it wont fall off while I'm riding and risk losing an important piece of bike safety kit. Well designed and great quality item.

Been on my bike for lots of rides and I can now say what a quality bit of kit this is. Garmin Varia is still attached and that's the most important thing. Highly recommended.

This bracket does not not fit tight and kerps movingWould I buy this item again NO

Excellent quality product easy to fit.
