Race Face Atlas 30 27. 5" Wheel World Cup Proven, Freeride Tested The Race Face Atlas line honors the company's freeride roots. It's a product line specifically designed for the rigors of freeride and downhill racing. Designed alongside Devinci Global Racing, the Race Face Atlas wheels are built for the most demanding riding in the world. Every aspect of the wheels were created with strength and durability in mind. The hub and bearing system is designed for longevity, smoothness, low drag, and zero play. The 6069 Aluminum rim connects to an oversized hub via brass nipples and 28 straight pull spokes to increase overall strength of the wheel and decrease unwanted flex. Like most modern mountain wheels, the Atlas rims come tubeless ready with rim strips already installed for easy tubeless setup. To top it off, the stealthy matte black paint finish with water transfer white graphics will look amazing on any bike setup. Whether you are a high level downhill racer, bike park slayer, or cliff dropping free rider, the Race Face Atlas wheels will provide the strength and durability needed to accompany your riding style.
