Seat Rail mount with saddle bag

Hi,

I did in the past installed it under the seat bag at the bottom of the seat post. It did worked, but felt not to be as much efficient than what I did instead.

I  unscrewed the varia locking part from the part toward the rubber mount and, after piercing 2 holes at the back my seat bag, screw it back there, with 2 washers to increase the contacting surface. It's higher and free from possible interference with the bag and mainly with the rear wheel.

Its working fine on my 1030+ and my 1050.
