The Iron Cross disc rims are designed for superior burp resistance with low pressure tube-type cyclocross clinchers. Any other tires will be very difficult to mount. The 20mm internal rim width provides superior tire performance. 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 Iron Cross disc rims haven't taken the suffering out completely. Stan's 3.30 Disc hubs keep the wheels affordable but light while still delivering the one of a kind ride quality. Rear hub size is 135mm 10 speed. If you wish to use both Cyclocross and Road Tubeless tires, we recommend the Alpha 340 Disc wheel.
For 11 speed rear use our new Iron Cross Pro, Team or Comp 2013 models This 10 speed model can not be upgraded to 11.
