The CrossRack seatpost bike rack allows you to mount a standard bicycle bag to almost any bicycle. Your cargo is centered on your bike and mounted in your slipstream to reduce wind resistance. The CrossRack bicycle seatpost rack system takes advantage of the ample space right behind you, especially on bicycles with small wheels, and puts your bag just where you want it. The CrossRack system is the result of more than three years of testing and refinement by our engineers who commute by bicycle and who sought the best everyday cargo solution.
The CrossRack seatpost bike rack works best with bicycles (folders and standard frames) that have sufficient clearance between the seat and the top of the rear tire. A minimum of 5 inches (125 mm) between the top of the bike's seatpost and top of the rear tire is required.
