The Stan's No Tubes Sentry MK3 rim is designed for riders looking for wide tire compatibility but not the weight typically associated with plus sized rims. Sentry MK3 rims are constructed from gradually tapered 6069 aluminum that is lighter and stiffer than some of the other alloys typically used for rim construction.
The Sentry 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 Sentry 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. Sentry MK3 rims are best used with 2.50-3.0" tires.
