XLAB Aero TT Water Bottle, Black, One Size

Product Information

Frame – The frame is one of the few mounts to use both the cage and the contained types of hydration systems. Most of the frame mounted hydration systems are the cage type, but there are a few contained types to go along with them too. The frame has some distinct advantages over the other types with the main one being that it is far less likely to be damaged during a crash or fall than the other types. Custom 66 mm carbon racing rage weighs only 20 grams, contributing to a total system weight of just 70 grams This allows you to get a great price on a carbon fiber cage mounted to the frame, though it is not especially secure or durable. Reasonably Decent

According to this study, an aero water bottle can save 1.6 to 3.9 Watts compared to a normal 500mL water bottle mounted on the downtube. However, the benefits are negligible below 19mph (30km/h). The true benefits only show if you ride at 25mph (40km/h) or above. Torpedo – The torpedo mount is actually just a modified front mounted hydration system and are always a contained system. In fact, the torpedo mount is how the first contained fueling systems were made with contained frame mounted hydration systems coming a bit later. Time gain per type of hydration system over the length of an Ironman distance in comparison with standard 500mL bottle fixed on the downtube

Let’s dig into the details. We will focus on the aerodynamic gains given by aero bottles but also by looking at different options for positioning the water bottles. We will see how much time you can gain and how many watts it can save. I will also review the regulations for triathlon and also for UCI road races about aero bottles. And finally, I will give you my honest opinion about buying aero bottles. How aerodynamic is a water bottle? Taking these results into account, it would actually be much faster for Jess to carry two 500ml bottles on the bike, placing one between her arms and one behind the saddle, as this would only create a 1.9w (40kph) / 0.8w (30kph) total penalty, compared with behind the saddle for the 900ml bottle which was 2.5w (40kph and 1.1w (30kph) slower. As with all products used for a triathlon, the weight of the hydration system may be just as important as all of the other qualities combined, if not more so. This does not mean that there is one “right” answer, but it does mean that you need to have an acute understanding of your body’s needs ahead of time. Another key difference between a road bike and a time trial bike is how they handle out on the road. 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.

Arguably the best quality of the Gorilla XT is the fact that it is made of carbon fiber, though this comes with some caveats too. When it comes to frame mounted aero water bottle, XLAB once again takes our top spot, though the competition is a bit more fierce. On top of that, a frame mounted hydration system is within easy reach for a cage type and is easier to refill for the contained type of hydration system. This type also suffers less destabilization than a rear mounted hydration system but more vibration that a front mounted hydration system. The Aero TT impresses us most with the inclusion of a carbon fiber cage that is less likely to deal with some of the durability issues other carbon fiber cages demonstrate because of its frame mounted position. The exclusive bottle/bottlecage coupling system, developed ad hoc, safely and securely holds the bottle even at high speed, a common occurrence in time trials.Placing it behind the saddle was best - 2.5w at 40kph and 1.1w at 30kph, and having it on the seat tube was 3.6w (40kph) and 1.6w (30kph) slower. It wasn't possible to fit the bottle between Jess' arms as it was so big! Remember, they will likely be using a fueling system as well, so it is more important that your hydration system feel as comfortable and natural as possible. While technically there are three primary mounts, the front mount actually has two different sub-mounts. One of the biggest selling points of many rear mounted hydration systems is their ability to accommodate multiple bottles. Designed for riders that prefer the feel of a more traditional bottle the Crono TT is a narrow, 66 mm, 400 ml bottle with an aerodynamic frontal area
