A bicycle pump is a must for every cyclist. Just pump up the camera or replace the punched one with a new one on the way, you cannot do without a bicycle pump. To choose a pump for a bicycle, it is worth determining what type of nipple is on your cameras (auto or presto). Most modern pumps have an adapter for both types of nipples, but if you have a French nipple, the adapter is worth paying attention to. It is also worth choosing pumps with a metal casing, such as an aluminum alloy. This bike pump will be lightweight, sturdy and won't rust. All pumps have frame fasteners - plastic holder and screws. There can also be pumps with a pressure gauge and without a pressure gauge. The pump should always be with the bike, as it can come in handy at any moment.
