Zipp 900 and Super 9 Compatible Disc Valve Hole Covers
This cover replaces the standard sticker or black tape that tends to be used to cover the valve hole on most Zipp disc wheels. However, not only does it cover the hole it also houses a magnet to work with rear mounted speed sensors. It is installed simply by locating both halves into the hole in the disc and then fastening with the supplied hex key bolt.
***** PLEASE NOTE WE HAVE THESE IN TWO SIZES THE LARGER SUPER 9 FIT HOLE OPENINGS OF 27MM X 58MM AND THE 900 FITS 52MM X 25MM*****
