The new Flow EX3 is an incredibly strong rim developed for enduro, downhill, and more demanding trail riding. Still lighter than competitors (580g for 27.5), the Flow EX3 is the ultimate rim for riders who push limits.
With slacker angles and better suspension, today’s “trail bikes” are more capable than many downhill bikes were only a few years ago. Factor in e-bikes, and it is clear riders are riding heavier, more capable bikes, and riding those bikes faster than ever. This rim can handle the fastest and most aggressive riders out there.
The Flow MK3 remains one of the best rims made for aggressive trail and all mountain riding, but the Flow EX3 is built to handle even more.
The specific position of the brace inside this triple cavity rim lets it withstand far more impact force than any alloy rim Stans have ever tested. The patented low sidewalls and stronger 6069 alloy construction together with a new bead-blasted finish and stronger overall rim shape make this the rim everyone is going to want in 2019.
This is the rim used by GT Factory’s Martin Maes to win both the Crankworx Whistler Enduro World Series and La Bresse World Cup DH last year. It enters the market with a proven track record of performance.

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 tyre insert, huge impacts can cause the sidewall of most rims to fold, causing air loss and eventual failure. 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 aluminium and WideRight 29mm inner width optimised for 2.35” to 2.8” tyres, 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.
