I am trying to find some carriers or even individual cogs for my cassette and have been told by numerous LBS and websites that shimano doesnt make or sell carriers or cogs for the 7700 dura ace cassettes. I would like to change my 12-13-14-15-16-17-19-21-23 to a 12-13-14-15-17-19-21-23-27.
I think I need one carrier with a 17-19 and another with a 21-23-27. Is this right? Or even possible? Can someone please point me in the right direction as to where I can find the carriers or order these individually?
thanks in advance
