INNOVATIVE ONEPIECE CONSTRUCTION
One-piece, no-bond manufacturing utilizes high-grade carbon fiber and YOELEO precision layup technique to eliminate the added weight and flex found in traditionally bonded bars, handlebars are much stiffer
CRAFTED WITH PROMOLDCORE
In the same vein, the implementation of ProMoldCore in fabricating our handlebars
has earned them renown for their stiffness. Experience hassle-free cable installation
as the latex molds the bar's interior, ensuring a seamless cable routing installationwith a sleek, smooth finish inside out.
Smooth inner,Easier Cable Routing Cable routing becomes easier and smoother
with ProMoldCore technology.
Handlebar GEOMETRY
YOELEO handlebar geometry is carefully designed to balance aerodynamics, comfort, and handling precision. With optimized reach, drop, and flare, our bars provide a natural riding position that enhances control in sprints, stability on descents, and comfort on long rides—so every mile feels effortless and efficient.
Bearing Cover Adaptors
Our bearing cover adaptors ensure a perfect fit between your headset and handlebar system, providing smooth steering, improved durability, and a clean, integrated look. Engineered from high-quality materials, they reduce friction, protect bearings from dirt and moisture, and maintain optimal performance ride after ride.
Handlebar Technology
ProOne and ProMold
Our YOELEO handlebars feature ProMoldCore and ProOne Technology for unmatched performance. ProMoldCore uses an internal latex mold to shape the bar’s interior, ensuring seamless cable routing, a flawless smooth finish, and superior stiffness for precise handling. Complementing this, ProOne one-piece, no-bond manufacturing uses high-grade carbon fiber and YOELEO’s precision layup technique to eliminate excess weight and flex found in traditional bonded bars. The result is a lighter, stiffer, and more responsive handlebar—engineered for aerodynamic efficiency, easy installation, and ultimate control on every ride.
