Deuter Bike Bag 1,1+0,3

This bag fits not only a spare inner tube but also a CO2 pump and other tools. Deuter’s quality holds up on two wheels as well—the brand known for its backpacks knows what it’s doing here too.

• Front attachment wraps around the seatpost
• Top attachment connects to the saddle rails
• Main compartment volume: 1.1 liters, plus an additional 0.3 liters with the expandable zipper section
• Outer fabric is made from recycled polyamide

Some cyclists protect the bike’s contact points with clear tape or protective film before using a bag like this—certain surfaces can be quite sensitive to strap contact.
