I currently own a 2011 Giant Rapid 3, and am thinking about converting to drop bars. One reason why I got a Rapid 3 is because it's almost Identical to the Giant Defy road bike (save for slight frame geomentry difference and obviously bar/shifter configuration), and at the time I thought I wasn't 'ready' for a road bike.

A friend of mine had a shop convert his Specialized Sirrus for something like $300. I priced out decent components (Giant drop bar, Shimano 2300 shifters, grip tape) at about $200 total, and wouldn't mind attempting the work myself (There are plenty of videos out there, and I'm very handy, hands-on and 'mechanical').

In general, do conversions require different cables and stems, and are there any other major component changes that should be taken into account? From the research I've done it seems like the Rapid drivetrain should be fine as is (derailleurs, chain, brakes, gear sets).

Also, I'm debating whether to sell the Rapid, I can probably get $450 for it (almost perfect condition, a few scratches here and there), and then just use the extra $300 to buy an actual road bike and save the time and effort of a conversion (although it may be fun!).

I know it's a common topic, but any input is appreciated! I know there are some out there who like throwing out their knowledge!
