OSX Riser Bar - 31.8mm Clamp

Chromag OSX Riser Bar with a 31.8mm clamp is a stiffness-to-control upgrade for riders who want confident steering without turning the front end harsh. Its custom-drawn 7050-series aluminum and carefully tuned tube shaping target durability where bars see the highest loads, while preserving the subtle flex that helps reduce hand fatigue on longer, rougher rides.

• 7050-series alloy construction - High strength-to-weight material choice for a dependable riser handlebar that doesn’t add unnecessary mass
• Custom-drawn tubing - Consistent material quality and shaping aimed at real-world durability under hard riding and frequent impacts
• Variable butted wall thickness - Reinforces high-stress zones while trimming weight in lower-stress areas for a more efficient build
• Tuned ride feel - Designed to maintain controlled flex for comfort and traction feedback instead of an overly rigid, fatiguing front end
• 31.8mm clamp diameter - Common stem interface for straightforward compatibility and modern cockpit setup
