I did a search and didn't come up with much informtion about these and we all know how us hipsters LOVE bullhorns, so I thought I'd post up some pics.
I went for these because they've got a nice deep drop and they're different. And different = expensive. I paid $60 + 5 shipping (they cost $10 to ship BTW, thanks King Kog).
They seem nice so far, but I've yet to ride them because my bike doesn't have wheels. I know I shouldn't let something stupid like that stop me, but I don't think my bike stand will support the extra weight.
Anyhoo, another bullhorn option for ya.
