If you look on www.bikegear.co.za, you will see Trax panniers on a GSA using the original frames.
I then contacted SW Motech in Germany and they make an adapter plate which fits the original frames.
For what its worth, the frames with the attachments look very Heath Robinson (IMHO) and not as versatile as the Motech QD frames.
You can get a full set through NN although there are cheaper suppliers.
If you do go ahead, please post pictures on here. I am test riding the 2010 model in a couple of weeks, and if I take the plunge I like the look of Trax panniers.
