Hi
Like to change my cassette on 2008 Sworks
has 50 /34 chain ring with 12- 27 t ,7800 derailleur.

I would like to change too 11 - 28 ,would this work, as i have heard that it is not possible with the compact crank?

Would there be any B screw adjustment, as looking at it , there may only be 2 threads left to turn..

Would any of the sram, ultegra, 105 cassettes works..

Thanking to all those who reply

yes and yes
