Rene Herse Randonneur 31.8 Ø Handlebars


The most comfortable handlebar, ideal for all-day rides. The gentle curve of the ramps supports your palms better than a flatter handlebar shape. This eliminates pressure points that can lead to numb hands and pain in wrists and elbows. It’s a shape that was developed when races were long and roads were rough.

To support your hands, the shape has to be “just right” – ours is based on a classic handlebar that was refined by randonneurs for their epic multi-day rides. Once you have ridden these, you won’t want to use any other bars for those long all-day rides.

Important! Set up correctly, the bars are angled upward so that the ramps are approximately flat. Only then do they provide the supreme hand comfort for which these handlebars are famous.

31.8 mm clamp. Also available with 25.4 mm clamp diameter.

Handlebar widths are ‘center-center’.

Polished (aluminum) finish. Made in Japan. 5 year warranty.

When done right, Randonneur bars provide unmatched comfort, but most current “Randonneur” bars do little except raise your handlebars by a few millimeters. After trying half a dozen Randonneur handlebars in various long-distance events, we concluded that the 1940s AVA Randonneur was simply the best shape. Instead of reinventing the wheel, we decided to offer a replica of the originals – now also available with a clamp diameter of 31.8 mm for modern stems.

Rene Herse Superlight (420 mm width) handlebars are made by Nitto to Rene Herse-exclusive specifications from extra-thinwall aluminum for the ultimate in light weight. They are heat-treated for ultimate strength. The “Superlight” specification can be used only for handlebars up to 420 mm wide.

Rene Herse Lightweight (440, 460 mm width) handlebars are made by Nitto from slightly thicker, but still very light, aluminum tubing to compensate for the longer lever arm of the wider bars. Heat-treated for ultimate strength.

All Rene Herse handlebars meet the most stringent EN “Racing Bike” standard for fatigue resistance.
