Why Use a Hydration Pack For Mountain Biking?

There are a number of reasons why hydration packs are the best choice for mountain biking including:

You can drink while keeping two hands on the handlebars

Unlike a water bottle, you don’t have to take a hand off the handlebars to drink. You can drink while navigating difficult terrain, while doing a wheelie or while moving downhill at a rapid pace. Being able to keep two hands on the handlebar makes it a safer hydration option than a water bottle.

You have less weight on your bike frame

If you have spent hundreds or thousands of dollars on a super lightweight aluminum or carbon frame, attaching 1 or 2 kilograms of water to the frame is a ridiculous idea! You want to keep your bike frame lightweight so you can handle tricky trails and perform jumps. By keeping the water on your back, your bike will remain light and agile.

It doesn’t interfere with you or your bike’s center of gravity

Having a hydration pack attached to your back keeps the weight in the middle of your center of gravity. It won’t make your bike feel imbalanced by adding kilograms of weight to a part of the frame.

You can carry more water

Hydration packs come in a variety of sizes, but 1.5 liter, 2 liter and 2.5 liter packs are common. This is a substantial amount of water that will be enough for a few hours of riding. If you tried carrying this much water in bottles you would have 3 or 4 bottles attached to your frame! Carrying extra water means you can ride further, ride harder, explore longer trails and you don’t need to find a water source to refill bottles mid-ride.

You can carry food and tools in your hydration pack

In addition to carrying a water bladder, most hydration packs have room for bananas, energy bars, spare tubes, bike tools and other items.
