Using this Ibera Alloy Rear Carrier is easy. First, adjust the length of the carrier according to your needs. Then, attach it to your bicycle's seatpost. Make sure the seatpost diameter is between 27.2 and 31.8 mm and use the included rubber sizing shims for a snug fit. You can quickly clip on your PakRak bags or other strap-attached bags to the carrier. If you want, attach a reflector or taillight for better visibility. When it comes to maintenance, keep it clean and dry. Avoid exposing it to extreme weather conditions. If it gets dirty, you can wipe it with a damp cloth. Don't overload it as it can only carry up to 10 kg (22 lb). That's all you need to know to enjoy using your carrier.
