Hello Forum Members,
I'm looking for some advice on finding the right type of nut and tool to fit a bottle cage to the 2x screws that stick out of the seat tube which the internal EPS battery is mounted to?
I have recently purchased a bike which didn't have nuts that came with it and having purchased a bottle cage wondered what type of nuts and tool should be used to hold the bottle cage securely?
Any help/advice greatly appreciated!
Thanks.
