Stan's Grail rim comes close to being the ultimate option for disc brake road and 'cross wheels. At just over 24mm-wide, and almost 25mm deep, it's aero, stiff, and ready to take the lead on the race course or on the road. Stan's own Bead Socket Technology offers unmatched tubeless setup for a wheel that's sure to please.
Stan's NoTubes BST design creates a tight tubeless seal between the rim wall and tire bead. The inner rim wall is the same size and shape as the tire bead. It's also shorter, which increases the volume of the tire.
