I think the "defect" in these wheels could be corrected with the addition of cloth rim-tape, judging from the picture in the article:


"October 23, 2008
Shimano American Corp. is recalling Dura Ace carbon clincher wheels for bicycles. Rim surface and spoke hole plugs on the wheel can cause a puncture to the inner tube, resulting in a flat tire. This can cause the rider to lose control and fall...


....This recall involves the Shimano Dura Ace Carbon Clincher Wheel Sets with model number WH-7850 C24CL sold for road racing bicycles. The rim has labels that read 'Shimano WH-7850', 'Dura Ace', and 'Carbon 1380.' These wheels are intended for use with high-end adult road-racing bicycles.

The wheels, made in Malaysia, were sold at bicycle specialty stores and dealers nationwide from April 2008 through August 2008 for about $1,300.

Consumers should stop using the bicycles with the recalled wheels, remove the wheels, and return them to their local bike dealer or retailer for a free inspection and repair..."
