I'm coming here for you guys collective wisdom. Here's the issue. I just bought a Specialized Rubaix Elite with SRAM Apex drivetrain. It has a compact double crankset (50/34) and a 11-32 cassette. I live in Central PA and montains are a fact of life. SRAM does not offer a triple crankset. And you cannot control one with the Apex brifter. I need more gears in the back,PERIOD.
I'm going to replace the rear deraliuer with either an X7 or X9 unit. I'll swap the cassette to 11/36 and replace the chain with a new longer one. I'll save the old bits for another project.
What I want to know is there any difference in the shift quality and durability of X7 and X9. We are talking 10 speed here. Is it wirth the coupla extra to go to the series 2 units. I'm leaning toward the X9 series2. Weight isn't really an issue. I'm not a weight weenie. Hell I weigh 190 and am pretty much a Clyde. So a few ounces don't mean diddly to me.
The bike is brand new. 2 weeks old, so calbes are not anissue. I'll be using the stock Apex brifters. Any help with which to purchase would be great.
Any suggestions on a cassette, I'm thinking a Shimano SLX or similar cassette. Any suggestions? Thanks for you're kind consideration.
