What's a water bottle? Oh...I remember...they're those things roadies use. I don't know Tarekith, water bottle mounts and many of the modern FS designs just don't seem to mix well. For me, I find a Camelback to be about as easy to use as the old water bottles. Plus I never like to be without the few tools and other emergency fix-it items that are in my pack. I notice many of the FS bikes at least have cage mounts on the front of the downtube, but this is one of the dustiest and/or muddiest parts of the frame. I have seen some trick and compact fanny packs that will hold one or two water bottles that would also work, and most of these have some small storage for a tube and those small tools.
