Using the Topeak Tri - Backup Pro Mount is easy. First, find the parallel rail section of your saddle. It's compatible with CrMo, Ti, and Carbon rails. Attach the mount securely to the rails. You can adjust it to two different angles according to your needs. You can place one or two bottles (up to 750cc each) on it. Just make sure the total load doesn't exceed 2.5 kg. When using it, be careful not to overload it. If you're using it with accessories like the Tri - BackUp Air Station or TubeBag, make sure they are properly installed. For maintenance, clean the mount regularly with a soft cloth. Keep it in a dry place to prevent rusting, especially since it's made of pressed aluminum. That way, it will serve you well for many races.
