My friends and I visited the Loire Valley in June 2015 and wanted to rent quality road bikes for our stay. Most of the options we found by searching online only rented cruising bikes (velos tout chemin, or "VTC") or mountain bikes (velos tout terrain, or "VTT").
Luckily, I happened across the web site for Cycles Contreau, based in Tours. I emailed the owner, Patrick Contreau, and he offered to rent us quality road bikes (Trek and Orbea) with solid components (Shimano 105) for 65E each per week. Patrick was tremendously helpful, knowledgeable about the region, and accommodating of our pick-up and delivery needs.
If you are a cyclist and want to rent a good road bike for your (amazing!) rides in the Loire Valley, look no further than Cycles Contreau. It's a top notch bike shop. read more
