One of the clients on our French grand tour kindly sent this in:
“Picked this up on eBay for £30 when planning a tour to France.
My bike has a plastic tank cover so bought the ‘strap on’ (!) version.
Fitted very easily on the bike and very secure. All round zip on zip off works well, 30 sec to remove or refit the bag. Been on and off at least 100 times now and still ok. Expanding to double size very easy and useful. Clear Map pocket and sat nav pouch too. Only down side is the rain cover , clearly the same cover as the magnetic version. No holes for the straps. O just cut 2 slots then backed with duct tape, passed straps through works fine. Easy to roll on and off and waterproof.
Recommended to store all your valuable stuff, so you can carry around when off the bike. Even has rucksack straps too.
Overall a Bargain !”
Both our guides also use these and I can highly recommend them if your in the market for a tank bag, decent capacity and lots of bargain to be found online…
