Rene Herse Randonneur 25.4 Ø Handlebars


Our most comfortable handlebar 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. We refined it so the shape ‘just right’ (unlike many similar bars that only raise your hands, but don’t really add comfort). Once you have ridden these, you won’t want to use any other bars for long rides.

Pro Tip: Angle your Randonneur bars upward so the ramps are approximately flat. It’s key to enjoying the supreme hand comfort for which these handlebars are famous.

25.4 mm clamp. Also available with 31.8 mm clamp diameter. For 26.0 mm stems, use a handlebar shim.

Handlebar widths are center-to-center.
