I already ride SRAM and have for quite a long time. I've been very impressed by their quality. I use their brake levers (lighter than XTR and like 1/3 of the cost), shifters, rear derailler, cassette. If they'd make a full gruppo of high end stuff, I'd be riding a completely SRAM bike. For the most part their stuff is top notch. Good quality, and reasonably priced. Unfortunately SRAM isn't making any disc hubs either, because my Shimano XT rear hub crapped out on me after less than 6 months of use. The axle was bent, and all the pawls inside had been broken out. I weigh 130 pounds and ride cross country, so I have no idea how I broke the hub. I've only recently had problems with Shimano. I hate their new 9 speed stuff, but I'll have to admit that their stuff back in the day was top notch. But now I just think for the price you can get better stuff. And stuff from a company that's willing to make compromises with the consumers about what they want. We'll see how Shimano fares after they completely move to the integrated shifting/braking.
