Stan's No Tubes S1 wheels use the same design principles as the Stan''s MK3 line, but with an emphasis on value and durability. 
Stan''s S1 wheels are built in the USA using 
Stan''s Neo Hubs, 
Sapim Race Spokes and Secure Lock Nipples.
The 
Baron S1 rim is designed for plus bikes. The 
Baron S1 rim features 
Stan''s BST for easy tubeless set-up and 
WideRight design for increased tire width without affecting the tread shape or side wall height. 
Baron S1 rims work best with tires from 2.8-3.2" wide.  
Baron S1 rims are made from 6061 Alloy and feature stainless steel eyelets.
Stan''s Baron S1 wheels come pre-taped  with tubeless tape. Just add some of your 
favorite sealant, valves and tubeless ready tire.
Stan''s S1 wheels do not include additional end caps but are compatible with any of the Neo end caps. Boost hubs currently only work with their stock configuration.
