SOME parts are NEARLY universal.
Almost all modern pedals will work with any modern cranks.
And almost all modern two-rail saddles will work with any modern two-rail seatpost.
Many parts, however, are not universal.
-Seatposts come in a number of different sizes (tubing diameter) and using the wrong size is very bad.
-Handlebars / stems come in a number of different "clamp sizes", and using the wrong size is bad.
-Cranks come in a number of different spindle types, and using the wrong type is bad or impossible.
These are the ones you're probably most likely to run into problems with.

The original poster who is a newbie should check the geometry of the bikes he is looking at and see if he could find a bike with similar geometry at a store and test ride it. If it fits, get the bike online. Geometry has to be close though. Within .5 or 1cm. and .5 degrees for the seat tube/head angle. Also, to complicate matters a little, compare the trail on both bikes. See
http://yojimg.net/bike/web_tools/trailcalc.php Plug in the numbers for the head angle, fork offset(rake), diameter of the tire you will be riding, and tire width. The trail on the bikes you are comparing should be within 2-3mm of each other. That should give you a good indication on the handling similarities. A lot of bike companies don't list their fork offset, sometimes you have to call them directly or email them for this, but if you can get the fork aftermarket online, they usually list the fork offset(rake).
You misunderstood what Seau Grateau (and I) were saying.
We weren't implying that he shouldn't buy the bike.
We were saying:
"Don't buy anything (to upgrade the bike) until you ride (the bike)."
He's talking about buying a bunch of new saddles and bars and wheels before his new bike even arrives. Which is silly.
