I have an '89 Raleigh Technium PRE that is black and I've swapped out most of the components to black. You can find the stuff but it probably wont be standard to the BL if you cant find a donor bike. There are black chainsets/cranks over at Nashbar that look snazzy and are very reasonable in the "road double" 53/39 version. For 50.00 it was a good deal and exactly what I was looking for. If you go that route, be prepared to also swap out the BB for the ISIS integrated unit. It's easy and cheap.

Dia-Compe makes sets of black sidepull brake calipers, rims/wheels might be a little more challenging but quite available.

The other day while resting in the shade on a distance ride an older lady was staring at the black bike. She looked at me and said, "that is a pretty bike". I would have preferred "villainous" but I knew what she meant.

Black Lightnings are my dream bike but since they are so difficult to find and usually priced in the 500.00 range.....my PRE will do just fine.
