yesterday I changed the drive belt and found that a glider (pos. 33) was defective and therefore the cam disc was incorporated into the drive disc. the weights are also down. when I just looked for a new vario fell on parts 36, 37 and 38 were not at all present!? it can be that I only need the just in this vario, that it varies a little from manufacturer to manufacturer?http://www.si-zweirad.de/…/index.php?… since a sp ortvario just 10eur more expensive than the original one is I thought to buy such a one. does the performance tech (below by me preferred for hilly against) really bring what or can one forget the underscore? it should be this:http://cgi.ebay.de/…egoryZ82225QQrdZ1QsssPageNameZWD1VQQcmdZViewItem or this:http://cgi.ebay.de/…yZ65343QQrdZ1QsssPageNameZWD1VQcmdZViewItem?… or this:http://cgi.ebay.de/…egoryZ65343QsssPageNameZWDVQQrdZ1QcmdZViewItem
