Lezyne Flow Tool Caddy

Yes, the Flow Tool Caddy is designed to fit standard bicycle bottle cages. It has a 73mm diameter, which is the industry standard for most cages on the market.

The semi-rigid shell and secure screw-top lid are highly water-resistant, keeping your tools and spares dry during rides in light rain or road spray. However, it is not fully submersible, so it is best to keep sensitive electronics in a sealed bag if you are riding in heavy downpours.

The rigid construction helps minimize noise, but because the interior is a hard shell, smaller items like keys or metal tools may shift on rough terrain. We recommend wrapping your tools in a rag or using a small piece of foam inside to keep everything quiet and secure.

Yes, the caddy is spacious enough to accommodate a standard road tube along with a multi-tool and a patch kit. If you ride with a larger mountain bike tube, you may need to pack it carefully to ensure the lid closes securely.

Unlike a saddlebag, the Flow Tool Caddy keeps your center of gravity lower and eliminates the risk of the bag rubbing against your seat post or thighs. It is a cleaner, more aerodynamic solution, though it does occupy one of your bottle cage mounts.
