How about all the crap tarty looking things that don't work very well like the Crank Bros Flatties that are not foot shaped,X-Lite seat clamps that don't,XTR Cranks that look five years old after one ride and those awful Nokon gear/brake cables that are made up from little metal segments that destroy your frame.
Just like the retro things we covet today such as Paul's mechs,biopace rings and really pony old forks
Form over function rules methinks
