I came across a wheelset (which I didn't even know I had!!) in the attic, and as I'm still doing "spring cleaning" they are now for sale. New/Never Used, but I didn't build them. Here are the particulars: Mavic Sport Rims (36o - polished -with perfect decals), these are tubular rims (390gm) and were built with steel rim washers - 14ga spokes - laced 4x to Maillard low flange hubs. No model number listed on the hubs, but perhaps 600?? 126mm spacing. Whenever/wherever I got these, they did not come with QR's (I always zip tie the QR's to the spokes on complete wheels) but I will provide QR's (something suitable!!) with the wheelset. My guess on these is early '80's (possibly late 70's). I've trued them and they are ready to roll (just add glue, tires and air!!). $80 (shipped w/QR's).
