Free up your frame with the revolutionary Fidlock TWIST 550 system: compact 550 ml magnetic bottle and magneto-mechanical base that permanently replace the traditional bottle cage. German design, intuitive ergonomics, cage-free mounting for optimal space saving on the most demanding geometries.

Summary: the bottle that revolutionizes cycling hydration

The Fidlock TWIST 550 embodies a radically new approach to cycling hydration. This system combines a 550 ml bottle in compact format (same footprint as the 450 ml model) with a magneto-mechanical base weighing only 16 grams that screws onto the standard inserts of the frame. No more bulky bottle cages: thanks to TWIST technology patented by Fidlock, the bottle attaches and detaches with a simple rotational movement, guided by powerful magnets and mechanically locked for absolute security, even on rough terrain. The total system weight (128 g) and its sleek design allow equipping the narrowest frames, where a traditional bottle cage would not fit. Designed in Germany with over 400 patents to its credit, Fidlock offers a standard that is gradually establishing itself in the world of MTB, gravel and bikepacking.

Technical highlights

• TWIST magneto-mechanical system: high-power magnets for automatic guidance + mechanical locking for maximum security. One-handed attachment and removal by clockwise rotation.
• Optimized 550 ml capacity: generous volume in a compact format (86 × 166 × 82 mm), ideal for tight frames and long rides without compromising on bulk.
• Featherweight: 112 g for the bottle, 16 g for the bike base, for a total of only 128 g — exceptional performance for a complete system.
• High-flow valve: self-sealing membrane ensuring high flow and total leak-proofing, with removable dust cap to protect the spout in extreme conditions.
• Studied ergonomics: ergonomic shape facilitating grip and compression of the bottle (flexible BPA-free polyethylene), even with gloves or while riding.
• Simplified maintenance: wide opening for cleaning, dishwasher safe up to 50°C, durable and UV-resistant materials.
• Universal compatibility: the bike base mounts on all standard threaded inserts (stainless steel screws included). Compatible with all TWIST bases (Uni Base, Tex Base) and all Fidlock connectors.

Geometry and mounting standards

The Fidlock TWIST bike base (106 × 25 × 14 mm, 16 g) mounts on standard bottle cage inserts (64 mm spacing) found on virtually all road, gravel, MTB and bikepacking frames. Its ultra-flat and discreet profile integrates visually with the frame without protruding. The system is designed to free up maximum space: lateral bottle removal by rotation, allowing the base to be positioned in areas where a traditional bottle cage would make the bottle inaccessible (sloping frames, rear suspensions, tight front triangles). The compact 550 bottle maintains exactly the same footprint dimensions as a 450 ml model, but exploits height to offer 100 ml of additional capacity — a valuable gain without lateral bulk penalty.

Available variants

• Smoke variant (translucent smoked): Ref. 09743-P00002(TBL) — most popular finish, allows visualizing water level.
• Black variant (opaque black): Ref. 09743-P00002(BLK) — maximum discretion, ideal for integration with dark frames.
• Clear variant (transparent): available — total content visibility, easier cleaning.
• Antibacterial variant (antibacterial smoked): Ref. AB-09743-P00002(TBL) — integrates FIDGUARD technology that inhibits bacterial proliferation in residual moisture inside the bottle, limits odors, derived from medical and food sectors.

All variants share the same technical characteristics (550 ml capacity, 112 g weight, full compatibility) and are supplied with the magnetic bike base, the TWIST connector and stainless steel mounting screws. The modular Fidlock system allows purchasing replacement bottles or adding additional bases (Uni Base for backpack, Tex Base for textile straps) without repurchasing the complete set.

Ecosystem and scalability

The TWIST 550 system is part of a complete range of Fidlock bottles (450, 550, 590, 600, 700, 750, 800 ml) and magnetic accessories (TWIST toolbox, VACUUM smartphone mounts). All TWIST modules are intercompatible: a single bike base can accommodate different bottles, and a 550 bottle can mount on any TWIST base. This unique modularity allows adapting hydration to each ride (compact 450 bottle for XC racing, 750 for a long gravel ride) without changing the base fixed to the frame. Fidlock, a German company founded in 2007 in Hanover, holds over 1,200 worldwide patents and has established itself as a reference in magneto-mechanical closure systems for cycling, outdoor and sports equipment.
