Circa 2012-13 New/Unlaced Hed Ardennes Rim Set.  18 hole front, 24 hole rear.  Listing is for the set.  For rim brakes, 23mm width (outside to outside), 19mm (inside to inside).  Machined braking surface, 450 grams each.  24 holer ear rim can be laced 2x/2x or 2x/radial, 18 hole front is for radial lacing.  590mm ERD (for wheel building calculations) These rims weren't available individually, as you sent your wheels to Hed for rim replacement.  Fortunately, I was able to get inventory from a recent retired Hed dealer.  So, if you're happy with your wheels but need a rim replacement, this is a great opportunity normally not afforded.  I have 5-6 other Ardennes listings on Ebay, including pairs and different styles.  Check them out if you feel inclined.  Buyer to pay $30 USPS Ground Advantage shipping with tracking and insurance.  Buyers outside the Continental US to use Ebay's International Shipping service.  Feel free to ask any questions and thanks for looking.
