The Stan's Flow MK4 is a wider, stronger, and laterally stiffer version of the previous Flow MK3. Today's Flow MK4 continues the progression with a 30mm wide asymmetric rim designed to build an even stronger overall wheel. Designed with input from Enduro World Series teams, the new Flow MK4 features a 30mm wide internal rim profile optimized for use with 2.35"-2.8" tires. The rim profile is slightly taller than it's predecessor with an extrusion rolled from a 6069 alloy.
This rim is fully tubeless compatible when used with Stan's Tubeless Rim Tape and a Wheelbuilder Tubeless Valve Stem.

The Stan's ZTR Arch MK3 is a wider, stronger, and stiffer version of the previous ZTR Arch EX rim. The use of 6069 alloy kept overall rim weight down despite growing in width by 24%. An entirely new rim profile adds strength and helps eliminate tire pinch flats. The Arch MK3 is optimized for use with tires ranging from 2.25-2.5"
Stan's Bead Socket Technology construction reduces the strain on the tire bead while creating a tighter seal. The curve of the rim sidewall is the same shape as the bead of the tire, like a ball and socket joint. This rim is fully tubeless compatible when used with Stan's Yellow Rim Tape and Stan's 35mm Mountain Valve Stem.
