My current CS-7800 12-23 is configured as follows:12-13-14-15-16-17-18-19-21-23t
Would it make sense to pop-out the 16t on my cassette and make it 11-12-13-14-15-17-18-19-21-23?
Can the 18t be removed or is it part of a fixed cluster? That would be cool since it would be than a standard 11-23 configuration at 11-12-13-14-15-16-17-19-21-23t.
Thanks for any advice!
