I recently swapped my SRAM Red 11-28 Cassette for an Ultegra 12-27 (much quieter with a DA chain). I noticed that the inside ring - a thin hollow cylindrical metal piece – of the SRAM cassette, which I'd like to sell, is lose. This is not the case for an 11-23 I have as well. Does this matter? Is it defective or broken? Can this piece be retightened? I'm wondering if this was the primary source of my noise.
On another note, I decided to install this cassette on a DTSwiss DT-240 shimano hub I have on another wheelset. It does not fit, but got terribly stuck. When I put some muscle into pulling it off, the entire free hub assembly came apart. Still had to tap the free hub off of the cassette gently using a hammer and flat head screwdriver. What a mess! Do these things go back together??
