Ok, I have a question about $500ish bikes. I am looking at the Trek 4500 and 4500 disc. I have been reading, mostly posted by Raiyn, that when bikes like this have disc brakes it takes away from other components. This seems completely logical, but when looking at the specs b/t the 4500 and the disc version, you'll see that there is no other difference in components, don't believe me? check it out:

So, is that line of thought just a relic of mountain biking history? Or am I missing something?
