With our Burra Burra Stabilizer Seatpack 10 you can say goodbye to the cumbersome weight and handling of integrated rear racks. Instead it affixes to your seatpost via an engineered aluminum stabilizer arm that minimizes any bouncing or side-to-side swaying under load. The pack itself features a welded roll closure design that's highly resistant to inclement weather while its smaller size (50x16x10cm) makes it ideal for smaller frames with tight wheel clearances.
