I arrived in Nantes 24 hours earlier anxious to ride my bike which accompanied me, partially disassembled, on the trip from the US. My derailleur had been disconnected from the frame and the chain got hopelessly twisted; which my attempts to correct only made worse. I rolled my bike to Urban Cycle and approached Arnold who left what he was doing to help me. He immediately dropped to the floor, popped the master link, and re-threaded the chain. While working he asked about my biking plans in Nantes, provided me with a map, and suggested other sources of information concerning cycling in the Loire-Atlantique.
I was prepared to have to leave my bike while the store worked through their repair requests. Not only was the repair immediate and the advice welcome but they did not charge me. I will undoubtedly need further service since this bike will remain in France, which I visit frequently. This will be the store that I will patronize thanks to their focus on customer service and satisfaction.
