- The number one thing a water bottle cage needs to be is secure. When riding the single-track trails and hitting berms your water bottle must not fall out. This applies to the road as well when you're going 20-30 mph. To ensure a secure water bottle cage Corki Cycles designed the bottle cage using a side entry mechanism. With most bottle cages they are attached centrally and over bumps your bottle falls out. Using a side entry water bottle holder is greatly reduced. - You can use the Cycles water bottle cage for all types of bikes. Whether you are hitting the trails, the road, or competing in triathlons, our water bottle holder will fit your bicycle. Use the water bottle cage arm to wrap almost any water bottle up to 1000ml/33 fl oz. Attach your Camelbak, Hydroflask, or classic cycling water bottle with ease. Suitable for mountain bikes, road bikes, city cruisers, and some full-suspension bikes. - The water bottle cage is made with polycarbonate. It's durable for thousands of water bottle attachments, while still being stronger than plastic, and ultralight. With the reinforced highly resilient water bottle arm, don't worry about damaging the holder even when you're reattaching your water bottle in a hurry. - The water bottle cage can be attached straight out of the packaging. Every order comes with an Allen key for immediate fitting. The bottle cage is easy to install and comes with 2 screws per bottle cage that will give it a firm hold on your bikes frame. The bottle cage is universally suitable to install on all bikes, while still protecting your frame.
