A friend brought me a box he found in his attic the other day and asked me to sell for him. It is a brand new, never used Aero Uni-Discs for a 27-700c road wheel in black. Basically it is 2 coated nylon disks and the hardware to mount to a road bike wheel. I have no idea how much this is worth or where to sell it but I figured this site was a good place to start for info. Thanks!
