The Stan's Flow EX3 is the evolution of the Flow line for aggressive riding on today’s faster and more capable bikes. It's made for handling faster speeds on the most demanding trails. The Flow EX3 combines the 29mm internal width and durable 6069 aluminum construction of the Flow MK3 with the incredibly strong triple cavity design of the classic Flow EX rim. The result is a new rim shape that balances radial compliance with lateral stiffness, and sets a new standard for durability and impact resistance.

The Tiebeam inner bridge lets it withstand impacts that would deform most rims to the point of air loss and structural failure. Combined with the added durability of 6069 aluminum and WideRight 29mm inner width optimized for 2.35” to 2.8” tires, the Flow EX3 is the evolution of the Flow line for aggressive riding on today’s faster and more capable bikes.
