Hydration just got smarter.

The latest Muc-Off x FIDLOCK bottle range combines secure magnetic-mechanical mounting, bold new graphics and two size options to suit different rides.

At the heart of the system is FIDLOCK’s clever mounting technology. Powerful magnets guide the bottle into place, while a mechanical lock keeps it secure when the terrain gets rough. When it’s time for a drink, simply twist the bottle to release it.

No traditional cage. No awkward reach. Just a clean, low-profile setup that’s quick and easy to use.

Two Sizes for Every Ride

The compact 450ml bottle is ideal for shorter rides, quick laps and bikes with limited frame space. For longer days in the saddle, the new 600ml version offers extra capacity without compromising on the secure, cage-free design.

The 600ml bottle also features a protective cap to help keep mud, dust and trail grime away from the mouthpiece, making it a great option for mountain biking, gravel riding and mixed-weather adventures.

Built to Ride

Made from durable, BPA-free material, the bottles are designed for regular use across everything from daily commutes to technical trail sessions.
