The weight capacity is very high and worth having. That is, it is only 36 grams. It places no additional burden on you while riding, allowing you to travel with ease. FLEXIBLE DESIGN: The bike water bottle cage has arms that wrap around the bottle to hold it securely and tightly, so you don't have to worry about it falling out while riding. Ensure a full water bottle is securely fastened while riding, whether you're cruising fast on the road or on bumpy trails. 3) EASY INSTALLATION: It takes less than 60 seconds to install this bike water bottle cage. Use a 3mm hex wrench to secure the stainless steel bolts to the bike rack. Easy to install and remove. IMPORTANT: Please check your frame for threaded holes (for mountain bike bottle cage mounting) before purchasing. 4) UNIVERSAL FIT: This lightweight MTB bottle cage is designed to fit most bike bottle sizes. Specifically designed for a single cyclist, it allows you to easily access your bike drink holder at all times while riding. Mount both cages on your bike for maximum hydration.
