Well, I've only heard so anecdotally (with extensive photographic documentation on these forums. Apparently, most every component of a bicycle can be easily replaced, excepting the frame (at which point it technically becomes a new bike). Personally I went with the 7.3 was because I liked most of the components and the "feel" of the bike itself. I don't buy into any of this rubbish about the ride being too rough. But then again, we have fairly well paved roads around town. I also like the styling, particularly the big 'ol wheels, the straight-bladed fork, the flat bars, and that great orange paintjob. But the flat bars are apparently (from what I hear) good for getting sore hands on long rides, and "drop bars" (the funny-shaped road bike ones) allow one to assume a more aggressive cycling position, so as to more easily and comfortably climb hills and/or get up to speed. Am I right on this? ANybody tried putting drop bars on a 7.3? Does it work?
