TUSITASeat Rail Mount Kit Compatible with Garmin Varia Rearview Radar

Works fine, allows RCT715 to be mounted at correct height and angle. Bike has a dropper post and Garmin supplied mount has no angle control and with dropper post RCT715 would have been too low. I have carbon seat with carbon rails, supplier suggest only using with metal seat rails. I added neoprene rubber to each side of clamp to prevent crushing seat rail but not really necessary since clamping no different to seat post clamp.

I know you can get lighter, 3D printed brackets for the Garmin varia units, but the build quality of this item (metal not plastic), and even the quality of the threads and hex bolts is exceptional.The flexibility of this mount allows you to fully extend the RCT715 to beyond the back of your saddle and still have a bag behind it.

Having been impressed with other TUSITA garmin mount kits, I bought this. It fixed easily in place, was easy to adjust, locking mechanism works smoothly and it feels nice and solid. Great purchase, verry happy.

As described

works just fine and seems to be very robust. A good design.
