Hey there, Just a quick question. I bought a second hand Profile hub off Ebay, and was told the driver is naffed. So i'm buying a new one and i need 16t to match my 24t sprocket. They're out of stock on Tarty at the moment and I need right now. So could someone please tell me because I have no idea, are these the same thing? http://www.alansbmx.com/product_info.php?p...s_id=2189{4}174 http://www.tartybikes.co.uk/product.php?pr...;category_id=28 Or if they're not the same thing, would they both screw on to the Profile hub? Thanks, James.
