If you have a power seat and can't find space for your Varia radar, this could be the perfect option. I noticed that another reviewer had a saddlebag that he didn't want to part with and found a creative solution with a GoPro under-saddle mount. In my case the power seat has a bracket in the back that it screws into and it works much better for me. With this mount, a GoPro quarter turn extender and a Garmin flange mount, I was able to mount the Varia with ease. Knock off the chainring because it doesn't fit snugly into the flange, so you may find the GoPro or other device moves a little when you hit a bump.
