"I travelled around 300km, including 220km on the Camino de Compostela (Lorgues to Arles). I didn't spare it anything: paths that weren't passable at all, its flexible structure that took the natural steps, puddles, etc... It held up well, with traces of wear on the tyres.
Conclusion: a great product that allows you to be self-sufficient, i.e. around 13kg that you can barely feel on the flat or going downhill. It's not as hard on climbs as it is on your back.
