Is the RC520 suitable 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 RC520 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.

Our commitments

Test Product When it came to testing this new RC520 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.
Guarantee : Lifetime warranty on the frame, 2 years on the fork, 2 years on peripheral components.
