I thought that was pretty darned nice of someone. I currently have 105 with an 11-25 that has caused me a bit of knee issue going up hills. They cared enough as well as paid attention enough during a ride to notice and hook me up.
This is
seriously awesome.
I recently installed the same setup on one of my bikes, replacing the DA 7800 RD/12-27 that was on there previously. (I tried the cassette by itself first - close, but no cigar.) You'll find it works fine in all 20 combinations.
Like the others have said - pass it on. Good begets good.
