The Fidlock TWIST Bike Base Adapter is the essential accessory for optimizing the positioning of your TWIST magnetic system on compact frames or when space is limited by the use of frame bags. Thanks to its precision-machined oblong slots, this aluminum adapter allows fine adjustment of your TWIST bike base position for perfect ergonomics.

Technical Highlights

• Exceptional travel: Move the TWIST bike base 26.5 mm up or down, providing a total adjustment range of 53 mm to adapt to all frame geometries.
• Robust aerospace aluminum construction: Machined from 6063-T6 aluminum alloy and black anodized, it combines lightweight (151 g) and strength while supporting a maximum load of 1000 g.
• Simple and universal installation: Mounts between the frame and the TWIST bike base on standard threaded bottle cage inserts. Four mounting screws included (2× M5×8 mm and 2× M5×16 mm).
• Full compatibility: Works with all Fidlock TWIST bike bases and fits all frames equipped with standard bottle cage threads.

Geometry and Design

With its compact dimensions of 105 × 15 × 6 mm, the adapter remains discreet while offering optimal structural rigidity. The oblong slots allow progressive position adjustment without requiring additional drilling. This elegant solution preserves the frame's aesthetics while providing unmatched mounting flexibility.

Recommended Applications

• Compact geometry frames: Optimize available space on small frame sizes where standard mounting points do not allow bottle installation.
• Use with frame bags: Avoid interference between your TWIST hydration system and your bikepacking bags or frame tools.
• Suspended frames: Adjust the position to clear rear suspension travel or avoid contact with the rear triangle.
• Dual bottle mounting: Install two aerodynamic bottles on the down tube and seat tube simultaneously, regardless of frame size.

TWIST System: Magneto-Mechanical Innovation

This adapter integrates perfectly into the Fidlock TWIST ecosystem, the revolutionary system that combines magnetic attraction and mechanical locking for intuitive and ultra-secure attachment. By finely adjusting your magnetic base position, you enjoy custom ergonomics adapted to your body type and riding style.
