This coincides with what can be regarded as the absolute cut off for what&#39;s offered in stocked spares, etc.Peterhttp://www.blogger.com/profile/15956486255735768304noreply@blogger.comtag:blogger.com,1999:blog-17091441.post-68656122325783680142009-10-28T15:11:57.632-04:002009-10-28T15:11:57.632-04:00Good thing I&#39;m still in 9-speed land on my &quot;modern&quot; bike (2003 LOOK KG281). Everything got simple once DA started toeing the line with regard to shifter and derailleur geometry. <br /><br />It goes without saying, of course, that I&#39;d be happy to work up some 7800/7900 compatibility charts for you. Just send some 10s goodness my way.<br /><br />(and it really goes without saying, if the good folks at Shimano want to send me any late 80&#39;s/early 90&#39;s marketing/sales material, I&#39;d love to scan &#39;em and make them available)Jeremyhttp://www.blogger.com/profile/17461713472346310708noreply@blogger.comtag:blogger.com,1999:blog-17091441.post-22270670251470545122009-10-28T14:30:52.048-04:002009-10-28T14:30:52.048-04:00It might be related to the fact that i work for Shimano, but I found the compatability chart to be very straight forward. You should see the doozy of a chart in the 2010 OE-manuals showing cross compatability between 7800, 7900 AND 6600, 6700 series components. (I&#39;m still not perfectly certain wether 7800 and 7900 cassettes are regarded as &quot;A compatible&quot; or not :-)Peterhttp://www.blogger.com/profile/15956486255735768304noreply@blogger.com
