600 ml Fidlock Twist Bottle with Gravity bike base mount.
The bottle twist was specifically engineered to do away with conventional bottle cages, to take up as little space on the bike as possible. Thanks to its minimalistic design, the bottle twist can fit even the tightest bike frame. The Gravity Kit includes a stainless steel band that surrounds the bottle for additional security.
Fidlock's Bottle Twist system has been upgraded with a "Gravity Kit" which is a slim, screw-on strap that encircles the bottle and better secures it to the latch.
