Stan's NoTubes Flow MK4 Front Wheel

The 30mm internal rim width is specifically optimized for tires between 2.3 and 2.6 inches wide. This range provides the ideal balance of tire shape, sidewall support, and traction for trail riding.

This is a 29-inch front wheel designed for a 15mm x 110mm thru-axle (Boost spacing) and uses a 6-bolt disc brake mount. Please verify your fork's axle standard and brake rotor compatibility before purchasing.

Stan's uses traditional J-bend lacing because it is the industry standard for serviceability. If you break a spoke on the trail or need a replacement, you can easily find compatible parts at almost any bike shop.

The Flow MK4 features Stan's signature BST-Asymmetric design, which is engineered specifically for easy tubeless inflation. The rim shape helps the tire bead seat quickly and securely, usually requiring only a standard floor pump.

The M-pulse hubs are built with high-quality Enduro bearings designed for ultra-low drag. This means you get a smooth, efficient ride with minimal friction, helping you maintain speed on technical terrain.

Yes, 6069 aluminum is significantly stronger than the standard 6061 alloy used in many other rims. Combined with a welded joint and a reinforced spoke bed, this wheel is built to handle the impacts of jumps and hard cornering.
