Product Information

If you need more than one bottle - particularly on half-ironman courses and longer, you're likely going to be using it for a concentrated solution with a bunch of calories in it. Many top athletes like this solution. With your swappable BTA bottle up front for water or course drinks, you're best off using the downtube (or seat tube) bottle for a good 1,000 calorie or so mix. You take small sips from this every now and again, and a steady stream from your BTA bottle, which is easier to get to. Since you won't be swapping this bottle, it makes sense to make it as aero as possible, and that means one of several choices. Specialized, Arundel, Bontrager, and Profile Design all make good bottles, some of them integrate better with certain frames than others. If you have a Specialized bike, get the Specialized bottle and mount it on the downtube. If you have a Trek, get the Bontrager and mount it on the seat tube (it fits better there). The general rule is to put it where it better "completes" the shape of your bike without leaving gaps. With the Mini Wing 105, this design combined with its other features makes this the best dual rear mount we came across, though it does come with some caveats not often seen with XLAB hydration systems. Up and Down For the two applications above, cage selection isn't critical - any decent cage will keep your bottles in place, because you aren't putting them on a rear-mounted bottle launcher. But if you really want a rear bottle, mount up a single one Chris Lieto style, right behind the saddle. You can do it with zip ties for the el cheapo solution (that's how Chris does it). But with a bottle behind the saddle, you'll want a good cage. The best cages have a solid lip that fits into the bottle's choke point. For bling factor, I like Arundel's Trident cages. They're pricey, but I've had a pair of them for six years, and they're still going strong. They've followed me from bike to bike. On the cheap, get a Specialized Rib Cage. They're fantastic. And if you're a Dash Saddles acolyte, they make the very snazzy TT9 with integrated cage bosses so you can skip the zip ties. 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 balanced answer would be to evaluate different people's needs, and evaluating the merits of different systems in different scenarios. But my gut can't let me do that. Well, not completely. Ideal storage will indeed depend on distance (a 5-mile ride won't require any, while a 112-mile ride will need a lot). But I have some pretty solidified opinions about hydration storage, and I'm gonna give 'em to you. In the end, that's why you're reading this anyway, right?

Since the RZ2 has to compete with the XLAB, it might seem like it falls a bit short, but this is still an incredibly capable hydration system. Carbon fiber is great for hydration cages because not only is it incredibly lightweight, but it is also incredibly strong for its weight. Finally, this hydration system maximizes its design with an aerodynamic profile as well as a non-slip grip. XLAB is the other company primarily known for manufacturing hydration systems which can be found in numerous Winner’s Circles from a wide variety of different triathlons. In fact, were it not for the fact that it does not come with a cage or mount and is heavier than the competing XLAB model, this would be the best performing frame mounted hydration system.Considering that their products are top-notch no matter what decision you make, it should only make sense that we include one such component that is featured on one of their larger systems. Because of this, we recommend that you use the Speedfil as a practice hydration system rather than for competition.

It is a pretty secure system. If you tighten to correct torque, you will have no problems. I got the Bontrager one to be higher up. The X-Lab Delta is more in the wind. (possibly due to shape of long Dash saddle.The biggest difference between the Mini Wing 105 and most of XLAB’s other rear mounted hydration systems comes down to materials. I have chosen to have just one bottle cage. It’s fairly easy to set up and fairly sturdy. (It weighed 170gram with one water bottle. This is great in case you want to keep your hydration and your nutrition separate, or if you prefer to have a bottle for cooling off mid-race. The first two have little aero drag. Some claim that having a bottle between the arms on the tribars reduces aerodrag. On the downtube, aero drag could cost 45g for a standard water bottle (according to tri-radar) For those of you who do not want to have to squeeze extra hard while riding, the RZ2 comes with a bottle that is much easier to squeeze than some.
