Rims

This rim is built to let you do more. The Flow EX3 is the most reliable tubeless rim made for handling faster speeds on the most demanding trails. Durability starts with design, and Stan's patented Bead Socket Technology ensures easy inflation and the most reliable airtight seal, proven time and again on enduro and World Cup DH courses around the world. Bead blasted 6069 aluminum construction and Stan's Tiebeam triple cavity design make the Flow EX3 the ultimate rim for enduro and DH racing and a great choice for the added weight and forces of eBikes, or anyone looking for the most durable tubeless rim. 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. The Tiebeam brace and patented low walls 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 29mm inner width optimized for 2.3" to 2.6" tires, the Flow EX3 is the evolution of the Flow line for the most aggressive riding. Every World Cup DH and Enduro World Series win, every hour of testing, riding, and improving, it’s all here in the incredibly durable Flow EX3, the rim that lets you defy limitations

The Grail MK3 rim is designed to let you ride without limits. Whether you’re rolling on fresh asphalt, crushing big gravel miles, or racing cyclocross, the Grail MK3 is ready to outperform the competition.

Stan’s patented tubeless technology can seal most punctures while you ride, for unmatched durability and peace of mind on every ride. The Grail rim’s versatile BST-R design is compatible with tubeless road tires, low-pressure tubeless converted tires, and conventional tires and tubes. The rim’s patented shape offers a more secure connection and airtight seal with tubeless tires and improves tire stability for superior handling in all conditions. The Grail MK3’s internal width and patented Bead Socket Technology rim design are optimized for 25-40mm tires. The truth is out that wider is faster, and the shape of the Grail MK3 rim lets you get the most speed from your tires, while also improving tire stability at speed and control in the corners. Nothing beats Stan’s patented tubeless rim design for getting the most performance from your tires. All the advantages the Grail MK3 offers on the road are even more noticeable once the pavement ends. For cyclocross and gravel racing, the optimized tire shape and added stability offer a distinct advantage. The Grail MK3’s rim shape is even designed to avoid tire pinch flats, allowing ‘cross and gravel racers to run lower pressures that absorb impacts and improve traction. No matter where your rides take you, choose the most trusted tubeless technology in the world. With the Grail MK3, there are no limits.
