Surly 24-PACK Rack Made of cromoly steel with stainless hardware, the Surly 24-PACK Rack is a front rack done right. When bolted to a compatible Surly fork, it yields a sturdy linkage to the mid-blade and crown eyelet, and it won't budge from there. Behold the 30 pound carrying capacity, and realize now why the front is ideal for carrying heavier loads. This is perfect for fat bikes and 29+ rides. Note: Not recommended for use with forks that have a single mounting point in the fork crown.
