Corrective action "spoke-hole plugs"

Replacing spoke-hole plugs by rim tape

DURA-ACE clincher tyre wheel sets 
WH-7850-C24-CL and WH-7850-C50-CL


We have found that there is a greater likelihood of a puncture in DURA-ACE clincher tyre wheels WH-7850-C24-CL and WH-7850-C50-CL. This is due to the surface texture of the rim in combination with the use of spoke-hole plugs.

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