This isn't really a TDF item, but this seemed like the best location. I will be in Bourg d'Oisans for 4 days of riding in late July - my biking trip of a lifetime. Unfortunately, I will need to rent a bike. The only shop I could locate in the town does not accomodate reservations. I don't want to roll the dice on getting a high-quality bike that fits. Any advice? Rent in Grenoble? Any leads? I'd also be grateful for other advice on where to stay, etc.
