Looking at upgrading my shifting system from Shimano SLX to Sram X9.. Which size Derailuer should I get and why?

I've run both X7 and X9 and my recommendation would be X9 shifters (bit different technology in them than x7, feel noticeably better) and X7 rear derailleur (used both, can't tell the difference between them, it comes in black).  Short cage will probably not work, so go with either medium or long.

Price Point has the Combo X9 shifters and Derailuer for $150...

Or from the same place, you can get the X7 for $44 and the X9 shifters for $84 and only be in for $128.

Worth every penny... as we discussed last night.

so you're saying X9 is not worth $20 more?

Darrin - why do you think that is an upgrade? I admit I've never ridden SLX, but I have ridden LX, XT, XTR, X9, X0 and all have served me well...

Anyway you can determine the cage you need by this formula:

Capacity Required (T) = (BIG ring - small ring) + (BIG cog - small cog)

The SRAM tech. manual lists the capacities of the different cage lengths...

I'm running a medium cage on my 1x8 set up, with 3 links taken out of the chain it's quite crisp. I'm running a x5 shifter (same as the x7 from a year ago but the x7 isn't available in a 8-speed this year) and a x7 rear derailer. I'm loving it and getting rid of the front derailer helped me with my KISS goal.

Sram = upgrade. The word is go long when running a triple setup, but have heard of peeps going with a medium. X.9. is nice but X.0. is the bomb :) The difference being a bearing rather than a bushing in your jockey wheel and adustable shift triggers on the shifters. X.0. Derailers can be had for $100 on ebay, shifters around $140. If thats above your budget, X.9. is a nice alternative :)

Scotty loves the shift key... X0 is way out of budget..

Luis, SLX is base Deore. Sram is a much smoother shifting system in my opinion.
