It seemed like a progressive city having bikes to borrow - promising for my chances of finally finding a professional bike shop. On the way into town, I stopped a guy on a Trek bike assuming he knew - he did and despite the language barrier, he managed to direct me to a street with several shops. 1, 2 and 3 bike shops with no proper equipment before the fourth and last turned out to be a success. Nice people and getting 4 tubes and extra patches/glue, for the first time since my good wheel broke, I felt confident I would make to Istanbul...
