Didn't they only make a very few of those?
Good luck in your quest.

I almost bought one of these 4 months ago, found on Craigslist in Minneapolis. Check to see if it may still be listed. Good luck, sweet looking ride.

I used Zoomthelist and found this one for the OP if he's interested (i'm not in the market for an Arc-X):

The Denver craigslist one is a good find (not the poster nor do I know him). Glad it wasn't available a month ago when I was looking.

Hi Matt,

I have one if you're still looking. Mine was handbuilt in Colorado and has a very unique wishbone seatstay, a level toptube for more shouldering clearance, and an Alpha Q CX-20 fork painted to match the frame. It's in excellent condition. Please contact me if you'd like more information and pictures.

best regards,
Bryan
