The Grail CB7 rim combines an incredibly light 300g weight with the stability, control, and reliability of the most trusted tubeless system. Today’s road and gravel tires have evolved. Yesterday’s slow-rolling 23mm tires and energy-robbing extreme air pressures have been replaced with wider, faster, and more comfortable tire designs. The Grail CB7 is the first rim built specifically around this new breed of tire.

  • Incredibly light 300g rim design optimized for tubeless tires and disc brakes
  • RiACT rim shape and carbon lay-up absorbs vibrations to give you the best ride possible
  • 21.6mm internal rim width for more stability and control with all tires
  • Tubeless ready to self-seal punctures while you ride
  • Patented BST-R tubeless rim inflates easier and offers a more secure tire fit
  • Register your rims for warranty and lifetime crash replacement
  • Optimized for 25-40mm disc road, gravel, and cyclocross tires



  • Custom built in house at Wide Open, just for you
  • Your choice of either Chris King or DT 350 hubs
  • All wheels include rim tape and tubeless valves, installed and ready to go
