ZTR Iron Cross disc rims are designed only for use with cyclocross tubeless tires and traditional cyclocross clinchers. Sure, bringing the world's best tubeless system to cyclocross turned out a little better than we'd even planned, but we promise the new ZTR Iron Cross disc rims haven't taken the suffering out completely. Now it just goes by much, much faster.
All Stan's NoTubes ZTR rims require yellow tape for tube or tubeless use. A tubeless valve is necessary for tubeless use. Tape and valve not included with rims. Please see the individual rim description for details.
