My current project couples a Mavic 840 rear derailleur with 821 DT shifters and a 556 rear hub (126mm -7spd). Could someone help me with what freewheels this get-up will index. This is my first go at the Mavic components. What beautiful stuff. Is there somewhere out there on the web that'll help me with the history and all of these groupo's. Thanks in advance for your time.
