Were the Edwins first? I believe so. The compound wasn't as hand-friendly as the basic black ones, but they were new and cool and you could put stickers on your bars that you could see through the grips. Awesome. I've actually got a pair on my fixed gear right now. They get the job done.
Then there were clear pedals.
Odyssey originally introduced the molded composite Twisted PC as a cheaper alternative to the regular aluminum Twisted pedal as well as a product for flatlanders, who have always preferred plastic. But something funny happened on the way to obsolesence. When "lightness" passed both "cleanliness" and "Godliness" in the "ness" pantheon, suddenly the lowly $12 plastic pedal became a favorite amongst slammed-seat street riders (as visions of pedal and Luc-E grinds danced in their heads) and miniramp shredders. Spindles were beefed up, basic black was joined by white, all rejoiced.
Then came clear. (Atomlab actually tried a clear Lexan pedal years ago, but they were a) expensive, and b) brittle.) At $15 a pair, the clear Odysseys became an instant staple—and helped offset the cost of things like Kevlar-beaded folding tires.
(Odyssey has continued to expand the PC line with a bunch of pastel colors and some tinted clear ones—based on the original iMac colors, which most of their would-be consumers probably don't even remember. PC? Mac? Oh, I get it. Can we just lose the red endcap next?)
Now we have clear seats.
Éclat, We The People's new parts line, is introducing the Webster seat, which doubles as a colander. A railed plastic seat full of holes—what a new concept! (Oh, that's right, they have a lot of colors now.)

Combine the clear version with a slammed post, clear pedals, clear grips, drilled-out bars and stem, a Grim Reaper frame and a tiny drivetrain, and you more or less have a bike fit for Wonder Woman.

I kind of thought the whole point of a seat was to HIDE the rails and the clamp and all that nonsense. Guess not. And I wonder what UV will do to it?
