Durability and an almost uncanny feeling of control on the trail have made Flow rims the preferred choice of multiple Red Bull Rampage riders and today’s Flow goes even further. The Flow MK4’s reinforced spoke bed combined with the offset drilling of the asymmetric design builds into an incredibly durable wheel that brings added confidence to every ride. Unlike many rims the BST Asymmetric shape is designed to equalize resistance to dents and tire bead retention on both sides of the rim under extreme conditions. Combined with Stan's patented Bead Socket Technology the Flow MK4 rim offers the easiest tubeless setup and most reliable airtight performance on the trail.

Low-profile 30mm internal width optimizes tire shape traction and control for 2.3-2.6” tires

Durable 6069 aluminum with welded joint and reinforced spoke bed

BST Asymmetric design combines Stan’s legendary easy tubeless inflation with a stronger more balanced wheel build
