Is that the same product as the SF-MX30? I shot JensonUSA an email and they gave me a very [s]uneducated[/s] unsatisfying reply.
They told me that the 2 products are different, but didn't back up their statement. But on Amazon, the product is listed as Shimano SF-MX30 DX Single Freewheel.The mx and the dx are different. Thanks and please let me know if you have anymore questions.
So now I am super confused.
