I wanted a bike bag that is more a "bag" a "briefcase" to carry provisions for a walk and keep the design "road bike" (Scott Sub 40). This bag is very responsive to what I was looking for: the width of the rack and just enough volume for a bottle of water, some fruit and a puncture bomb. The four Velcro attachment to luggage hold well, the bag never moved. It comes with a shoulder strap, which can keep it on oneself when leaving the bike, and with a bag for rain that the content does not take water. Anyway great article for amateur road cyclists.
