I just bought a bike that came with the magnificent Shimano Altus group
, while it's enough for my needs "towing kid around", I wanted to try the hype of SRAM and see how does it works. I heard it requires less cabling, never misses a shift, shifts quicker, more reliable, can work even if you forget to put the cables, weights less then 1g... you know, all the things you can read around. I just got a pair of X7 shifters on ebay for cheap now I need the RD, cassette and chain. From the Altus group you can figure out that the bike also have a cheap frame and probably not worth of upgrades so I'm looking to spend the least.
So back to my question, if I go with the X7 shifters and a 9sp X4 RD, am I going to be missing anything in the SRAM Hype experience? or should it perform as good as a pair of X7's? I've always heard that it's the snifter that matters and the RD is of little importance. What do you think?
