Stan’s Crest MK4 Tubeless Rims – 27.5" & 29"

A true icon in mountain biking history, the Crest rim debuted in 2005 and evolved from Stan’s earliest designs, including the legendary 355 rims. Built to be light, durable, and tubeless-ready, the original Crest set the standard for fast, reliable wheels. Today’s Crest MK4 pushes that legacy forward with lightweight 6069 aluminum, welded joints, and an asymmetric design that balances spoke tension for a stronger, more reliable wheel while keeping the spirit of the original: fast, serviceable, and flat-resistant.
