DURA-ACE WH-7850-C24-CL clincher wheels

We have found that Shimano Dura-Ace WH-7850-C24-CL wheels
have a greater likelihood of suffering a puncture. This is due to
the surface texture of the rim and spoke-holes coming in contact with the inner tube.

The condition can be easily eliminated by replacing the spoke-hole
plugs with genuine 18 mm high pressure Shimano rim tape.

What to do?
*If you’re consumer with affected wheels, or bicycles equipped with them, stop using the bicycle, remove the wheels, and return them to their local bike dealer or retailer for a free inspection and repair.

*If you’re retailer with affected wheels in your shop, please replace the spoke hole plugs with rim tape. We will be happy to provide the required rim tape free of charge.

To obtain the rim tape or if you require more information, please contact Shimano American Corporation..
