Saddlebag
From Wikipedia, the free encyclopedia
In cycling, a saddlebag or seat bag is a bag attached under the saddle, used mainly to hold bicycle repair equipment, such as spare inner tubes, tube patches, glue, repair tools and waterproofs. Some cyclists also keep a first-aid kit there in case of injuries. Seat bags are common on touring and racing bicycles, but are also popular with cross country mountain bike riders.
The capacity of a seatbag may vary from tiny to large depending on the length of ride, likelihood of flat tires or other mechanical failure, or possible assistance needs of other riders in a group.
Smaller bags, often known as seat bags, wedge packs, seat packs fit completely under the saddle. Saddlebags are usually larger bags which project behind and sideways. The best-known of these larger bags is probably the Carradice Long Flap, for many years a staple of British cycle tourists.
Recumbent bicycles have much larger seats and special luggage is available which attaches to the seat; these are also called seat bags but are typically the size of small touring panniers.
