Hi Alain,

I'm planning a solo RTW trip with the Giant Loop Great Basin too on my R12GSA. To secure the bag to the bike I have removed my pillion seat, which requires the key to remove it, and replaced it with an Alum. plate that attaches into the same mechanism. The plan is to insert a plate in the base of the bag that bolts to the seat plate. That way it needs the key to remove the bag.

This still doesn't secure the zip and contents, so I am trying to find travel suitcase zipper tabs that allow a padlock to feed through the tabs. I am also anticipating the zip failing eventually and looking at using the 3M heavy velcro used for attaching helmet cams etc., to supplement the zip for closure.

I will also be carrying a 49L Ortlieb waterproof bag with a 12L Pacsafe portable safe inside for electrical goods. This can be cabled and padlocked to the bike in a way that secures the Ortlieb bag also. I carry that bag virtually empty so I can put my riding gear inside when I stop and walk in comfy clothes. 95% of my gear will be in the Giant Loop.

I use the shoulder strap from the Ortlieb bag to carry my tank bag around when stepping away from the bike for a meal or sightsee.

Like you I have read widely about the beneficial use of a bike cover and use one that covers bike and gear completely and can be padlocked at the bottom.

I figure that if they really want my gear they will get it but making it a little more difficult will prevent impulsive theft a bit.
