Shimano issues wheel advisory
Shimano found that the spoke plugs shipped in lieu of rim strips with its Dura-Ace WH-7850-C24-CL wheels have a greater likelihood of producing a puncture due to the surface texture of the rim and the spoke holes coming in contact with the tube. Therefore, Shimano has issued a voluntary recall of the spoke hole plugs. The wheelset will not be recalled. The fix is to remove the spoke hole plugs and replace them with a 18mm high-pressure rim strip.
