Is the RC500 bike designed for bikepacking?

Yes, this bike was designed for bicycle touring on roads, including bikepacking. That means you can install light bags, for example on the saddle, on the frame, and on the handlebars. Thanks to its comfort, the RC500 is the perfect companion for long journeys in the saddle.
This bike is not however a bike for travelling. We do not recommend overloading it with larger travel bags on the pannier rack, for example.

Store your bike in a dry, cool place. If riding or storing your bike in a salty environment, be sure to wash your bike after each use.


When it came to testing this new RC500 bike, we certainly didn't hold back.
In the lab, the bike passed all of the tests for the most demanding standards, as well as additional tests that helped guide our design choices (geometry, fork rigidity, etc.).
But that wasn't all. We also put it through its paces on the road. We tackled some legendary races (Paris-Roubaix, Tour des Flandres, the Ardéchoise, etc.) as well as our lunchtime rides and even gravel rides and long-distance rides with panniers.
