The ISIS BB for a double has a shorter spindle than for the triple. ISIS BBs for doubles are still 'out there', as are ISIS cranksets for double BUT this system was crappy and I recommend a shimano crank and BB 'system' that will thread into your english threaded BB w/o issue..and it won't cost much..go see a decent LBS and talk to them.
Your BB shell is threaded and the specs-68mm wide and 1.37by 24..BB30 is a 42mm diameter 'system', without threads..a system not compatible with your frame and no advantage anyway.
