Welcome to the forum Shoshi.
A shame there has been no response as its a question I've have need to be answered myself in the future.
Not long ago we had a knowledgeable poster "Il Padrone" who I would have steered you towards with this question.
I believe he might still be found in the Thorn cycle forums.
Another avenue might be asking the question in here: http://www.mbtc.org.au
I think he was an active member of one of the Victorian cycle touring groups but I understand that there are a few and maybe not the one above I've offered.
However, someone in there should be able to steer you in the right direction - fingers crossed.
Please come back and update us with any answer you find, so others travelling in your tire tracks might benefit.
