Saddlebags / Saddle bags / Saddlebag / Saddle bag

So Skive, do you use a Bagman support for your large bag? If so, how do you attach it?

Looking into something around a 15 litre, but no strap hoops on my Rolls saddle, so I'm looking at options for attachment.

one of these.
straps go through the metal loops.
unit attaches to the saddle rails.

you can get the cheaper one and run the loops straight through the rails.

there are a ton of mods on the net that people have come up with.
