The Grail MK3 Disc Brake Rim was designed for rolling on fresh asphalt, crushing big gravel miles, or racing Cyclocross.
Light, strong, and laterally stiff, the patented shape and 6069 series aluminum construction of the Grail MK3 makes it ideal for longer and more difficult rides both on and off the pavement. Stan’s patented tubeless technology can seal most punctures while you ride, for unmatched durability and peace of mind on every ride. The Grail rim’s versatile BST-R design is compatible with tubeless road tires, low-pressure tubeless converted tires, and conventional tires and tubes. The rim’s patented shape offers a more secure connection and airtight seal with tubeless tires and improves tire stability for superior handling in all conditions.
