Stan's Grail S1 Wheels are based on Stan''s Grail rim with a more wallet friendly build. The Stan''s Grail Rim is a modern road rim that is compatible with road tubeless, low pressure tubeless converted and tubed tires. If you are using a 32mm road tubeless tire, air pressures can be run as high as 70psi.
Along with Stan''s tubeless technology, part of what sets Stan''s wheels apart from other companies is their WideRight rim profiles. For each rim Stan''s makes they tune the rim width to work with an optimal tire width range. For the Grail S1 Rim, Stan''s recommends that you use a 25-40mm tire.
Setting up the Grail S1 Wheels tubeless couldn''t be easier, Stan''s preinstalls a double layer of their 21mm tape. All you will need to add is a 44mm tubeless valve and your favorite tire sealant.
Stan''s Grail S1 Wheels pair the Grail S1 Tubeless Ready Rim to Stan''s Neo sealed bearing hub with Sapim Force Leader spokes and Sapim SecureLock brass nipples.
Grail S1 Rear Wheels use Stan''s latest version of the Neo hub with DuraSync 6-pawl freehub body. DuraSync freehubs have 6-pawls to provide a super quick engagement of 10-degrees and 36 points of contact. For better durability and to help carry load forces better, DuraSync hubs use 3 sealed bearing vs the 1 or 2 in a traditional hub.
