Sram 1:1 actuation derailleurs

[bobswire]

I'll be building up a cummute type all rounder using sram 10 sp bar end shifters and was wondering thoughts from those of you who are familiar with Apex and X9 sram rear derailleurs. I like the looks of the X9 for the build or would you suggest I stick with the Apex?

Maybe this can help

3. In a switch, SRAM’s 10-speed mountain bike derailleurs (XX, X0, X9 & X7) are now compatible with their 10-speed road shifters (Red, Force, Rival & Apex). So you can use Rival shifters with a XX rear derailleur and wide range X7 10-speed cassette for mountain centuries.

10s barends are compatible with only sram 10s rear ders. Like their road ones and MTB ones. X9, the 10s one, is a higher end component than Apex..more durable, IMHO.

I got a good deal on the X9 10SP med derailleur ($50) new take-off figuring it would be more durable than the Apex (as you stated).
Grazie,

I have an apex on my cross check and its not even in the same league as the X9. The Apex feels cheap and doesn't shift as well as the nicer der. I would not go with an apex.
