Hi again! Thanks for answers about "first carbtops". However, I have looked them through thourougly and compared with the kind with 6 mm cables. The differences Iīve noticed are as following: first kind-41,5 mm slides, later kind-46,5 mm slides. first kind-tops marked 28 and lower top screw, later kind-non marked tops and higher top screw. first kind-small cable adjusters to be adjusted with a 7 mm tool-later kind-bigger cable adjusters to be adjusted with a 10 mm tool. first kind-5 mm cables and a thinner devider(1 to 4 cables), later kind-6 mm cables and a thicker devider. First model top screw look similar as the one from K1 and K2 but it isnīt ecact the same. Iīm pretty sure no one else will notice the diference, if someone has mounted the K1 top screw, eccept the mounter himself. Regards, Bo from Sweden.
