Bike Saddle Dual Bottle Cage Extension Holder

Keep Hydration Close on Every Ride

The Bicycle Saddle Water Bottle Cage Extender is designed for riders who want secure, easy access to hydration without cluttering the frame or handlebars. Mounted behind or under the saddle, it creates a stable platform for one or two standard bottle cages, making it especially useful for MTB, gravel, road, and long-distance rides where extra fluids matter.

Crafted from durable PC material, this saddle mount adapter offers a rigid yet lightweight structure that withstands regular off-road vibration and everyday commuting. The compact bracket (approx. 105mm x 85mm x 75mm) fits neatly under most standard saddles, using the included hardware set for straightforward installation. Once fitted, it provides mounting points for up to two bottle cages, accommodating a wide range of common cycling water bottles and drink cups. The design also allows you to utilize the space behind the saddle for additional light accessories such as small saddle bags, mini pumps, or repair kits, helping you organize essential gear without interfering with pedaling or steering.

The low overall weight (approx. 72.5g for the holder) helps maintain bike performance while redistributing the weight of your bottles closer to the bike's center line, which can contribute to more balanced handling compared with loading the handlebar area. This makes the extender suitable for mountain biking, training rides, touring, and endurance events where stability and access to fluids are important. The package includes one Bicycle Saddle Bottle Cage Extension Holder and a matching accessory hardware set for mounting. Bottle cages and bottles are not included. Please note that minor color variations and small measurement deviations may occur due to manufacturing and display differences.

Why It's a Smart Choice

• Increases hydration capacity by allowing one or two rear-mounted bottle cages.
• Uses otherwise unused saddle space to keep the frame and cockpit clear.
• Lightweight yet sturdy construction supports regular MTB and road use.
