Truly massive bag. Perfect for everything but racing. Bought this for RAGBRAI 3 years ago and it's been on my bike since. Sure it adds some weight but the amount of stuff it will hold is just awesome! If you only go out on 20 mile out and backs it's probably overkill. If you tour, commute, or love centuries (or doubles), this is your bag.
