The Fidlock TWIST Bottle 550 Compact Single revolutionizes bike hydration by combining generous capacity (550 ml) and ultra-compact format. Thanks to its optimized voluminous design, this bottle takes up no more space than a standard 450 ml, while offering 100 ml extra for long rides. Ideal for frames with tight geometries or minimalist setups, it combines ergonomics, magnetic security and high flow rate.

TWIST patented magneto-mechanical system

The Fidlock TWIST system frees the bottle from its traditional bottle cage: a powerful magnetic connection combined with a mechanical lock ensures firm and intuitive attachment. The bottle clips magnetically onto its base then unlocks with a simple twist movement. No more bottles lost on technical singletrack! This Single version includes the bottle with its magnetic connector; the Bike Base mount is sold separately or in the complete pack.

Technical highlights

• Optimized capacity: 550 ml in the footprint of a 450 ml, perfect for tight frames or frame-bag configurations.
• Featherweight: Only 112 g with integrated connector.
• High-flow self-sealing valve: Self-sealing membrane guaranteeing generous water flow without accidental leakage.
• Removable dust cap: Protects the nozzle during muddy or dusty rides.
• Proven ergonomics: Textured shape for natural grip, intuitive one-handed operation.
• Premium BPA/BPS-free materials: Food-grade polyethylene, dishwasher safe up to 50 °C (remove connector).
• Universal TWIST compatibility: Works with all Fidlock bases (Bike Base, Uni Base, Tex Base Multi) for modular mounting.

Dimensions and geometry

Height 166 mm, width 86 mm, depth 82 mm: these reduced proportions allow equipping modern bikes with wide tubes and shortened frames (full-suspension MTB, aero gravel, e-bikes) without compromising triangle space or bag placement. The compact format avoids interference with knees, oversized front wheels or onboard equipment.
