Minimalism to the max is a good description of the ultra-lightweight seat pack for road bikes and mountain bikes. The Ortlieb Micro Two Seat Bag was specially designed for those demanding tours when every gram counts. In addition to being 100% waterproof, the pack offers you space enough for a few critical items such a replacement tube, a bike kit or first aid materials. Its roll closure and elastic drawstrings allow you to collapse its size down to a minimum. And thanks to its extremely small dimensions, it can be mounted to your bike in an extremely space-saving manner. Simply attach the mounting bracket to your seat rails. Then attach or detach the pack with a single hand using the snap buckle. While the snap-on system was again enhanced for user friendliness, the Micro Two remains compatible all predecessor models. Not suitable for carbon seat posts and carbon saddles!
