The Fidlock TWIST 800 ml replacement bottle embodies German excellence in the service of long-distance cycling hydration. Designed for demanding rides and endurance raids, this large capacity bottle stands out for its universal compatibility with the TWIST ecosystem and its modular system that extends the lifespan of your equipment. Manufactured in Italy with premium BPA-free materials, it guarantees healthy hydration and optimal performance.

TWIST Belt-Only System: innovation at the heart of the 800 ml bottle

The TWIST 800 ml bottle adopts Belt-Only technology, a major evolution of the Fidlock magneto-mechanical system. Unlike smaller capacity models, this version integrates a flexible and resistant strap screwed onto a special connector, ensuring ultra-secure hold even on rough terrain. The magnetic connector attaches and detaches with a simple lateral twist in the clockwise direction—an intuitive gesture, accessible with one hand while riding.

Design and ergonomics: the bottle for long escapes

• Generous 800 ml capacity: Ideal for rides over 3 hours, sportives or bikepacking where water points are spaced out.
• Soft BPA-free polyethylene material: Excellent compressibility for optimized flow, even at low pressure. The body deforms easily to facilitate liquid extraction.
• Self-sealing high-flow valve: Watertight membrane with large water passage. Removable dust cap to protect the spout when mounted under the down tube.
• Dimensions compatible with wide frames: 77 mm width, 256 mm height—the bottle integrates on modern geometries (gravel, MTB, large road bikes).
• Featherweight 104 g: Italian performance—remarkable lightness for a bottle of this capacity.

Modularity and ecology: the principle of intelligent replacement

Fidlock designed the TWIST 800 with a circular economy logic. When your bottle shows signs of wear—clouding, scratches, residual odors—no need to repurchase the entire system. Simply unscrew the Belt-Only strap from the connector (using a coin), transfer the magnetic connector to the new bottle, reposition the strap, then tighten the screws. In a few seconds, you're back with a like-new bottle, while preserving resources and your initial investment.

Available variants

• Black: EAN 4251207402678 / Ref. 09651-P01002(BLK)—sober and elegant matte finish.
• Smoke (translucent smoky grey): EAN 4251207402661 / Ref. 09651-P01002(TBL)—allows visualization of remaining hydration level.
• Clear (Transparent): Ref. 09651-P01002(CLR)—maximum content visibility for optimal control.

All three colors share the same technical characteristics, dimensions and compatibility. The choice is based solely on your aesthetic and functional preferences.

Compatibility and maintenance

This replacement bottle fits all TWIST bases: TWIST bike base (standard frame mount), TWIST uni base (universal mount), TWIST tex base (backpack/bag straps). Thanks to this versatility, you can use the same bottle on different bikes or supports without constraint. Dishwasher safe (without the connector), it simplifies maintenance after each muddy or dusty ride. Fidlock also integrates FIDGUARD technology which inhibits bacterial growth in residual moisture inside the bottle.
