I don't want to step on your thread but I have a Shimano cassette question....
Just purchased new wheels from a reputable and noteworthy BF'er and am awaiting delivery. I want to purchase a new cassette. I currently have a 10spd 12/23 105. A 10spd DA CS7800 12/21 is about $110 and an Ultegra CS6700 12/23 is about $100. Would there be any significant/noticeable changes upgrading to the DA?
Thanks, Mike
