Bontrager GR Pro IsoCore Gravel Handlebar

The Bontrager GR Pro IsoCore Gravel is a high-end handlebar specially designed for gravel, bikepacking and adventure enthusiasts. Made from OCLV carbon with integrated IsoCore technology, it reduces additional vibrations by up to 20% compared to a conventional carbon handlebar, ensuring outstanding comfort on the most demanding terrain.

Its 15° flare significantly improves stability and control on technical sections, whilst the short 70 mm reach and 120 mm drop facilitate access to the controls and enhance manoeuvrability.

With its ‘Adventure Fit’ design, the handlebar offers optimal wrist clearance during prolonged weight shifts. Laser-cut lever guides simplify positioning, and its compatibility with clip-on extensions makes it a versatile choice for long distances.

Available from 400 to 460 mm at the top and up to 520 mm at the drops, the GR Pro IsoCore adapts to all riding styles, whilst remaining lightweight, stiff and perfectly controllable.
