Ok noob question - what do you mean with the 1:1 and 2:1

One convention' date=' used by Shimano, is one-to-two (1:2). A unit of cable moved in causes about twice as much movement of the derailleur.

Another convention, used by SRAM mountain bike rear derailleurs, is one-to-one (1:1). A unit of cable moved in the shifter causes about an equal amount to be moved in the derailleur. SRAM claims that this makes their systems more robust: more accepting of contamination. ^[11']  "

 

 

Hope this helps explain it.
