Hello Greg,
thanks for the info about the US shipping, I didn’t know that.
Please note that I’m neither a dealer, nor interested to make money with Strida parts, I just want to supply support as far as possible.
Of course, I would beg for refund of all costs (parts cost, shipping and maybe paypal fees).
You will find the amounts in a private mail (upper left)…and you might be surprised.
As already mentioned above, it would be the Aluminium version.
You did know that there is also a special tool needed to change the freewheel?
Descriptions are here, please scroll down to tool “T”.
Be careful when purchasing these tools, the prices at the web are strongly different (Shimano was seen from ~ 12,50 up to 78 US$ !)
Sorry, I’m unable to recommend Strida France due to very bad personal experience…
