Best. Seatpost. Bag. EVER.

The Ortlieb Seatpost mounted bag is great for people who don’t want or can’t install saddle mounted bags because you can switch the bag between bikes frequently.

The Ortlieb Seatpost Bag medium has the integrated ratchet mount that allows you to quickly install and remove the bag from your bike and A fixing for a rear light or reflector.

Please note that this product is not recommended for carbon fiber seatposts.

The waterproof PU coated nylon and Cordura fabric paired with the roll closure will ensure that your gear stays dry. The Small Ortlieb Seatpost bag can hold just about 1.5L

These bags stick out just enough to help minimize the dreaded rooster tail from dirt and water.
