Turbine Riser Bar - 31.8mm

RaceFace Turbine Riser Bar - 31.8mm is a purpose-built mountain bike riser handlebar for riders who want a precise, dependable cockpit without the weight and fragility tradeoffs of carbon. Built from cold drawn, seamless, butted, shot peened Air Alloy aluminum, it’s engineered to handle hard trail use while keeping steering feel direct and consistent.

The 31.8mm clamp diameter fits the most common modern MTB stems, making it an easy performance-minded upgrade or replacement for trail, all-mountain, and enduro builds. Like most alloy bars, it can also be trimmed to fine-tune fit and control for different shoulder widths, riding styles, or tight terrain.

• Cold drawn, seamless Air Alloy aluminum - consistent material quality for reliable strength and predictable ride feel
• Butted construction - targets material where it’s needed to balance durability with a competitive weight for an aluminum MTB handlebar
• Shot peened finish - improves fatigue resistance for long-term durability under repeated trail impacts
• 31.8mm bar clamp - broad compatibility with modern mountain bike stems and straightforward setup
• Cut-to-fit width - can be trimmed to match rider preference, terrain, and steering leverage needs
