Loved by cyclists worldwide

The Seatpacker rack totally eliminates side to side movement (Tail Wag). Plus it works with dropper posts! Its slim front design and reinforced front panels completely eliminate thigh rub.

    I am very happy with this bag. I was looking for something stealthy enough to use on my racing style road bike for day rides, including sprinting out of the saddle and long out of the saddle clmbs, yet with sufficient room to not worry about extra clothes, food, water and the like. Zero thigh rub, even sitting back on long descents, and no detectable sway or movement whatsoever. Because the nose of the bag, where it is closest to the saddle, is rigid, stuffing it is easy. No worries about what goes where. The outside top pocket was an added bonus, fitting my exactly 6 inch phone just right, with enough room for a Powerbar left over. Keep in mind that the outside pocket’s seams are not sealed, and therefore not waterproof, according to Kevin at Arkel, who was very responsive to questions over email. It shipped and arrived much quicker than stated in the ordering process. Great product from a great company. Thank you!

    I have three bikes with not so very long seat posts. It fits to all of them without anly problems. Because of the frame the bag is very stable. No problem with riding out of the saddle. I would highly recommend it. Shipping to Germany was very fast, around 4 working days.

    Sweet bag . Just off the Columbia – Western Rail Trail. This seat bag was awesome, providing the storage needed along with great stability. Highly recommend this product..

    A great product.
    I’d highly recommend this seat pack to anyone who owns a carbon framed bike and wants the extra storage capability.
    Super easy to put on or take off, but the bag does sit higher than the seat, so it’s easy to clip the bag with your leg when getting on or off your bike.
    A big thumbs up.
