Carrying around a backpack full of water, tools and spare parts has been the choice of mountain bike riders for years. The reason for this was because there were minimal options for anything else, especially when it came to full suspension bikes. Bikes had very little room left for carrying water bottles and often only went to a single place to fit a small bottle, sometimes in very difficult to reach places.
Today there is a trend with riders who want the freedom from carrying around a backpack and instead prefer to carry everything on their bike. The riders have been brilliant strapping and hiding the stuff on the bike. With the Machine, we have made room to fit three bottles (or something else) on the frame, two inside and one outside the front triangle. Now you can carry hours of water and even use one of them nifty water bottle toolboxes.
