Buyer’s Guide to Buy Triathlon Hydration Systems

Buyer’s Guide to Buy Triathlon Hydration Systems


The selection of the kind of hydration system mostly depends upon the personal preferences of the athletes. But for every athlete, the proper hydration system is essential to keep the body hydrated all the time during competition. 

Contained – This is the easiest to use a hydration system, but it also comes with some issues. A contained hydration system is usually a front mounted hydration system. The only problem with a contained hydration system is that it takes quite a long time to refill.

Cage – This is a straightforward hydration system to use, and it can hold any liquid in it. This cage system does not aid the transfer of water in any way as it does not come with any automatic way of distribution. The main advantage of this cage system is that it is effortless to refill. The main issue with this System is that it does not hold the bottle securely. 


The mount of a hydration system defines how easy it is to use and carry. Just like the type of hydration system, the selection of mount also depends upon the personal preferences of the athletes. But it is essential that it always five the most comfortable and natural feel. There are three primary mounts where the front divided into two different sub-mounts. 

Front – This is the most widely used mount for the hydration systems because it offers effortless access to everything. This is a cage type of System that you can fix at the front of the bike. This provides a high level of convenience to the bikers they can easily and quickly grab the bottle. This mount does not create much vibration, but the bottle can easily slip away from it on rough terrain. 

Torpedo – This is a contained system, and a type of modified front mounted hydration system. The main benefit of this mount is that there is no need to carry and hold the bottle to drink water. You can sip the water through its extended feeder tube. The only trouble with this mount is that it takes more time to refill and the feeder tube can also cause leakage. 

Frame – This type of mount included both cages and contained a kind of hydration system. The frame mounts are less prone to damage than others, especially during crash and fall. This type of mount is straightforward and quick to refill, and also offers ease of reach. The main problem with this System is that it creates more vibration. 

Rear – This is a cage type of mount for the hydration system. The main benefit of this System is that it looks familiar to most of the bikers. This is because most of the bikes come with a rear cage, and thus it does not feel anything like new. The main problem with this rear mount is that it takes more time to use, and it also creates more vibration. 


The weight of the hydration system is also a significant factor to consider while buying. You have to choose the right weight according to the needs of your body. Choosing an inadequate hydration system will not be worth spending money as it will not fulfil the desired task. On the other hand, selecting a heavyweight system will consume your more energy that can put effects on your race. Thus, choose the weight carefully by considering all the essential factors.
