Using your Surly Rear Disc Rack is easy. First, make sure your bike has seatstay - mounted disc brakes like the Straggler, Krampus, or Karate Monkey. Adjust the height of the rack according to your wheel size, which can be from 26 to 29 inches. Once it's adjusted, use the stainless - steel hardware from the reusable Surly Tool Bag to attach the rack securely to your bike. When loading items, ensure they are well - secured and don't exceed the 30kg (66 lb) weight limit. As for maintenance, regularly check the hardware for tightness. If the rack gets dirty, you can clean it with a mild soap and water. Avoid using abrasive cleaners that could damage the tubular CroMoly steel. Also, remember that the 'RK' part numbers RK013, RK0121, RK0134 won't work with this new rack, so don't try to use them.
