Good news. I completely added Sram x7 shifters and der's on my bike and added an x0 cassette. My bike shifts very nicely.

Now to the problem.

My wifes mountainbike. I put on my x3 rear der and shifters. Used my old wheels. everything works well. I have the rear der working fine. The problem is her front der. it's the original one (only a year old but a real cheapie one). I can't get this thing adjusted. I can get it into the middle chainring by using the barrel adjuster but the minute I use the shifter, it goes back to skipping it. I would put my old shimano alivio on hers but hers is a bottom swing and mine is a top swing. thanks for your help
