i don't see the point of dropping a lot of coin on things like handlebars, stems, and seatposts, hell even cranks. fit first, price second. a cheap pair of handlebars that fits you is better than the $90 nittos that look nice but feel terrible.
i'd put money first into bearings. bb, hubs, and maybe headset. then i'll put down good money for a saddle that feels good. from there it's kinda whatever i can get a great deal on easily
