The
Stan's No Tubes Grail MK3 Rim is their latest generation rim designed for road, gravel, and cross use. The Grail MK3 Rim upgrades from a 6061 alloy to the same 6069 alloy found on the Stan''s MK3 mountain rims. The 6069 alloy drops the weight of the
Grail MK3 Rim by 20g to 440g and improves the ride quality.
The
Grail MK3 Rim like the rest of Stan''s rim line use their patented BST and WideRight technologies. BST rim beads all you to easily set up your
Grail MK3 rims tubeless and in some cases depending on the tire, even without an air compressor. Stan''s WideRight technology, optimizes the tire width to be paired with the rim to make the most out of the sidewall and tread shape.
Grail MK3 rims are best used with 700x25-40mm tires.
Setting up the
Grail MK3 Rim tubeless, you will need
Stan''s 25mm tubeless tape and
44mm tubeless valve. For tire pressures over 40psi you will need to install 2 layers of Stan''s Tubeless Tape.
