CX Tape is a double-sided tape used in addition to high quality tubular glue to ensure the best bond possible between cyclocross tubular tires and tubular bicycle rims. CX Tape can be used on either carbon or alloy rims, the special formula adhesive found in the tape reacts with tubular glue to fill voids between the base tape and the rim bed. CX Tape should be installed by a professional mechanic or experienced individuals only.
