When going for a bike ride it seems there is always more than fits in the pocket. Now you could stuff things down your shirt like those riders in the Tour de France, or you could use a bag or pack. The problem with the under seat bag is that it makes accessing items difficult. The Serfas Stem Clamp Bag System puts the bag on the bars, and while we don’t recommend actually riding and in motion, it is a lot easier to quickly stop and open the bag while still straddling the bike. The system includes a few attachments and options, including a large carry all bag, and even a hard case. Video after the jump
