The Entity BC45 Side-Pull Bottle Cage was designed to keep your water bottle in place even when bouncing down the roughest of terrain (where many bottle cages fail and your water bottle gets ejected mid ride). The Z shape of the BC45 cage ensures a positive connection with your water bottle with a broader contact area yet, with a significant diagonal opening, allows you to reach down and grab your bottle firmly and quickly.The side access makes it an ideal cage for smaller frames, dual suspension mountain bikes or with cramped bottle space or bike packing set ups where frame bags limit the ability to pull bottles out upwards. However, the BC45 is very versatile and absolutely great to use in all frame types and sizes, offering a more intuitive bottle pull action and optimal bottle security.Constructed from glass fibre-reinforced polyamide the BC45 is very durable and weighs only 35 grams.Features: Incredibly light at only 35g Glass fibre-reinforced polyamide construction is durable, supple and attractive Z shape construction adapts to bottle shapes and keeps bottle securely in place Fits all bikes with bottle cage mounts
