Product Information

Full details

The Fidlock Twist 550 Compact is ideal for cyclists with narrow bike frame geometries who need a streamlined, clutter-free hydration solution. Its primary benefit is the innovative magnet-mechanical mounting system that replaces bulky traditional cages, allowing for effortless one-handed removal and secure attachment; however, users should note that the system requires a bike frame equipped with standard threaded mounting points.

FAQs

Is the bottle dishwasher safe?

Yes, the bottle is dishwasher safe at temperatures up to 50°C.

Can I use this on a bike without mounting holes?

The system is designed for frames with standard threaded bushings; use on frames without mounts is not supported.

Does it come with the bike base?

Yes, this set includes both the 550ml bottle and the matching bike frame base.

Is the material BPA-free?

Yes, the bottle is manufactured from BPA-free polyethylene.

Will the bottle fall off on bumpy trails?

The combination of high-strength magnets and a mechanical locking mechanism provides a very secure hold, even on rough terrain.

Troubleshooting

Bottle feels loose when attached

Check that the base is screwed tightly to the frame and ensure there is no mud or debris trapped between the magnets on the base and the bottle.

Bottle is difficult to remove

Ensure you are twisting in the correct direction; the system is designed to release with a specific clockwise or counter-clockwise twist motion rather than pulling directly outward.

Pros and Cons

Pros

  • Extremely secure connection on rough terrain
  • Perfect for bikes with limited space inside the frame triangle
  • Minimalist aesthetic with no bulky bottle cage
  • Easy one-handed operation while riding
  • Dishwasher safe up to 50°C

Cons

  • Not compatible with frames lacking standard threaded bottle bosses
  • Proprietary mounting system requires Fidlock bases
  • Smaller 550ml volume may require more frequent refills on long rides

Setup, Compatibility & Care

Installation requires a standard bike frame with M5 threaded bushings. Simply align the Fidlock bike base with your frame's cage mounts and secure it using the provided hardware. The system is compatible with all other Fidlock Twist base mounts, allowing you to swap bottles between different bikes if equipped with the same system. For care, the bottle is dishwasher safe up to 50°C. Ensure the mouthpiece is rinsed regularly to maintain hygiene, especially when using sugary drink mixes. The dirt cap should be cleaned periodically to prevent debris from reaching the nozzle.
