Bullmoose bars... they were invented by Tom Ritchey back in 1980 and for a time they were the bar to have on an mtb and they are friggin' tough.

New ones will set you back $150.00... bet I have a few used sets up here I could send for the cost of postage if you can't find them anywhere else.

They are really nice bars but there is only a vertical adjustment to them as they are fixed.
