● Built to handle the added speeds and increased forces of today's longer travel trail,
enduro, DH, and E-bikes
● Tiebeam triple-cavity rim design resists damage and prevents air loss under impacts
● 29mm internal width optimized for 2.35” to 2.8” Trail, All-mountain, and DH tires
● Most trusted tubeless system for easy setup and low maintenance
● 6069 aluminum alloy is stronger than conventional 6061 alloys
● Bead Blasted “BBQ” finish for added durability

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.
The Flow EX3 rim's Tiebeam inner bridge lets it withstand impacts that would deform most rims
to the point of air loss and structural failure. Even if you use a tire insert, huge impacts can
cause the sidewall of most rims to fold, causing air loss and eventual failure. But the Tiebeam
brace and patented low sidewalls of the Flow EX3 resist this folding, maintaining air pressure
and structural integrity better than any other rim. 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 and E-bikes. Every World Cup DH and Enduro World Series win, every hour of testing, riding, and improving, it's all here in the Flow EX3.
