Stan's Flow EX3 Rim - 29 Disc Black 32H

The Flow EX3 is the most reliable tubeless rim made for handling faster speeds on the most demanding trails. If you’re looking for the ultimate rim for Enduro and DH racing something to handle the increased weight and added speed of an E-bike or just want the most durable rim possible this is it. 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 perfectly balances radial compliance with lateral stiffness and sets an entirely new benchmark for durability and impact resistance.

Patented low-profile tubeless rim design balances lateral stiffness with radial compliance

Designed tested and raced to victories on the World Cup DH and Enduro World Series circuits

Built to handle the added speeds and increased forces of today’s longer travel trail enduro DH and E-bikes
