Rene Herse Randonneur Handlebars

Unlike standard bars that often have a flatter transition, these feature a gentle, upward-sloping ramp. This shape is designed to cradle your palms, distributing weight more evenly across your hands to reduce the pressure points that typically cause numbness on long rides.

Yes, they were specifically developed to handle the vibrations and demands of rough road cycling. The ergonomic shape provides a stable, comfortable platform that helps absorb road chatter, making them an excellent choice for endurance gravel or mixed-terrain adventures.

These handlebars use a 31.8mm clamp diameter, which is the standard size for most modern road and gravel stems. As long as your current stem is designed for 31.8mm bars, they will be compatible.

The 460mm width is relatively wide, which is intentional for this design. This extra width provides better leverage and stability when navigating rough terrain or riding fully loaded, while also offering a more open chest position for easier breathing during long-distance efforts.

Because of the unique ramp curve and reach, you may find that your hand position sits slightly differently than on a traditional drop bar. You might need to make minor adjustments to your stem length or saddle position to dial in your reach and drop, so plan for a bit of fine-tuning during installation.
