Zefal Z Box M Tool Holder

Zefal Z Box M Tool Holder

The Zefal Z Box M is a no-fuss tool storage solution that mounts directly into any standard bottle cage, keeping your tubes, tyre levers, CO2 cartridges, and other trail essentials secure and completely dry. If you'd rather free up your jersey pockets or avoid a bulky saddle bag, the Z Box M offers a clean, low-profile alternative that works on any bike with a cage mount - road, gravel, MTB, or commuter.

At 0.6L capacity across its 17cm length, there's enough room for a full emergency repair kit without adding noticeable bulk or weight to your setup. The polypropylene construction keeps the total weight down to just 80g, so you'll barely notice it's there until you need it.

Waterproof and Secure

A screw-cap closure seals the Z Box M tight against rain, puddles, and road spray - keeping CO2 cartridges, cash, and anything else inside bone dry regardless of conditions. No more arriving at a breakdown with a soaking wet tube or corroded cartridge threads.

Universal Fit

The Z Box M slides straight into any standard bottle cage, meaning there's no drilling, no straps, and no permanent modifications required. Swap it between bikes in seconds - a handy feature for riders running multiple builds or sharing gear between a road bike and a gravel rig.
