....The Mavic SSC group is bad........really bad...... don't bother looking for them in eBay, you are just wasting your time.....An Alvit can outshift an 840 0r 851 RD any day......
Seriously though, The Mavic 840 should be pretty good, based on its slant parallelogram design, seven speed capacity (I think it even goes up to 8 speeds) and indexed or friction shifting capability and the OP should check them out. I honestly cannot say the same for the older 851 SSC RD though. Better than other straight parallelogram RDs, because of it's adjustable height jockey wheels and cage, but it will never match a slant parallelogram derailleur's performance. Bonus with the 851 is the cool styling and the very light weight. It's kind of a balance of enough good things so it's my favorite C&V derailleur.
