ISIS bottom bracket - drive side 'cap'
#1
Hey guys,

Trying to remove an ISIS bottom bracket from a '06 Trek 1200. Bought the 8-notched cup removal tool (similar to http://harriscyclery.net/merchant/370/images/large/bbt18.jpg), removed the non-drive side no problems, loosened the drive side cup fine. But no matter how much I try to unscrew it, it won't come off! It seems to be on the last thread, but not catching on to 'exit' the screw hole..

Anyone have any idea what's going on here? Also sorry if i'm misusing terminology here, feel free to correct me. Thanks. (:

There is nothing to keep the thread itself from continuing to exit, so there must be something else impeding movement, probably the end of the screw that holds the cable guide to the BB shell is catching on the end of the cartridge. Remove the screw and see if that solves the problem.
