I bought & installed the chrome Rack with the Pannier side loops to hold the bags away from the rear wheel. Each of the horizontal cross rungs of the rack slide over smaller pipe stubs on the side pieces, the rear having tabs to screw sides to. I used JB weld to permanently mount all the cross rungs, while installing. I also made 2 mounting plates so I could use the rear Seat Rail with this Rack. The Rack is very strong, & good looking, it suits me & my purposes very well. I have carried a heavy top bag Bungied to it, & am working on bags over the winter months. I would recommend this Rack, especially if using different directional signals.
