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

BST TECHNOLOGY:
BST rims are designed to match the shape of your tire's bead to create a safer and more secure air tight interface
Bead Socket Technology rims are designed to match the shape of your tire's bead to create a safer and more secure air tight interface. Unlike the secure "socket" of a BST design, conventional rim shapes drive the bead of the tire down deeper into the rim, putting pressure on sidewalls that causes friction, restricts tire volume, and keeps the interface from forming a sufficient seal for tubeless use. BST rims secure the bead of the tire, not the sidewall, creating an air tight seal while allowing the tire's sidewall to expand to its true, rounder, more effective profile. The result is more traction and less rolling resistance. With lower-profile, less vulnerable sidewalls, our BST rims are also lighter and stronger by design, and accelerate more quickly
WIDERIGHT TECHNOLOGY:
We all know the most important piece to the bicycle-terrain interaction is the contact patch between the tire and terrain, so tire profile and tire pressure play huge roles in bicycle performance and overall handling. But many rims just don't work well with the tires we're all using. Rims that are too narrow fail to offer sufficient sidewall support and protection to your tires and create a less stable shape. The result is less control in the corners, less traction on climbs, and more rolling resistance. Rims that are too wide also distort the tire profile, decreasing traction and control and driving impacts directly into the rim, negating the impact absorbing advantages of a tire's volume. Our WideRight rim widths are designed to strike the perfect balance between tire volume and sidewall function
Though its roots can be traced back to the original Flow and Crest rim designs, we officially began the WideRight design philosophy with the introduction of our carbon rim shapes. With our new MK3 (always pronounced Mark 3) series, WideRight expands to our aluminum rims.
WideRight rim profiles allow the tire to achieve its proper shape, and that's the foundation for a great handling, fast-rolling, and responsive bike.
Our WideRight system makes it easy to find the perfect rim width for the tire size and volume you ride. Too narrow of an internal rim mixed with a high sidewall design gives you a "light bulb" tire profile while an ultra wide rim on a narrower tire will give you a flat to "bell shaped" tire profile. Neither of these scenarios give optimal tire profiles nor allows the tire to perform as intended.
WideRight profiles provide the optimal volume without distorting the tread pattern or the side knobs so each part of the tire is in the correct position for rolling and cornering, allowing for maximum traction and control as well as offering minimal rolling resistance. The WideRight profile advantages don't stop there. Proper tire profiles not only allow for optimal tire performance but also allow the tire to do its secondary job of protecting the rim as well as the tire's sidewall. A flat or bell-shaped tire profile leaves the tire exposed to sidewall cuts and creates undue chances for rim damage
