Fidlock TWIST Bottle Kit 450ml — Translucent Black

The complete Fidlock TWIST experience, ready to install straight out of the box. The Fidlock TWIST Bottle Kit 450ml in Translucent Black gives you the full magnetic bottle system — bottle, connector, bike base, and mounting screws — so you can go from delivery to riding in under five minutes.

Fidlock’s patented TWIST technology magnetically snaps the bottle in place and only releases when you give it a TWIST. Never lose a bottle on the trail again. As the smallest bottle, the 450 is perfect for small frames or for those who like to ride light.

The Translucent Black colourway gives a sleek, semi-opaque finish — dark enough to look considered on any build, translucent enough to monitor your hydration level mid-ride without removing the bottle.

What’s in the Kit

• TWIST Bottle 450ml — soft BPA-free polyethylene body with self-sealing high-flow valve, removable dirt cover, and translucent black finish
• TWIST Connector — the magnetic-mechanical interface that attaches the bottle to the bike base; removable before dishwashing
• TWIST Bike Base — the frame-mounted base that accepts the connector via magnetic snap-and-lock; installs using standard bottle cage screws to standard braze-ons — make sure to use the provided screws when attaching the bike base
• Mounting Screws — included; use the provided screws rather than your own for the correct installation torque and thread specification

How the TWIST System Works

Strong magnets attract, centre, and latch the bottle magnetically to the base. The mechanical locking keeps the module securely attached to the frame — ensuring comfortable and safe handling, even under strain.

Unlike traditional cages that can rattle or loosen over time, this system ensures hydration stays secure so riders can focus fully on the ride. The only way to release the bottle is a deliberate twist to the side — no accidental ejections on rough terrain, drops, or rock gardens.

Three-step operation:

• Snap: Bring the bottle near the base — magnets attract, centre, and lock it automatically with no alignment required
• Drink: Squeeze the soft polyethylene body and drink through the high-flow self-sealing valve; replace the dirt cover when not drinking
• Twist: A single side-twist releases the bottle from the base for refilling, cleaning, or switching bottles

Is the TWIST 450ml Right for My Frame?

The 450ml is the smallest TWIST bottle — perfect for small frames or riders who prefer to ride light. If your frame has tight triangle clearance or limited bottle cage space, the 450ml is the correct choice over the 600ml. Check the Fidlock Bottle Fit Template to find the right bottle for your bike — available on the Fidlock website — before ordering if you have any concerns about frame clearance.

For frames with more space where higher hydration capacity is needed, the TWIST 600ml kit is the larger alternative in the same magnetic-mechanical system.
