I bought this to help me in Ironman 70.3 Weymouth. So glad I did. Compared to similar products with other brands this represents excellent value and the quality, look, design, ease of fitting, ease of use, ease to clean, ease to refill in race or training on the go in first class. An essential for any triathlon when using tri bars. The product fits to the bars easily, is adjustable for when you adjust your tribar position. It has more than one cap solution so you can choose which way, one of which suits bumpier terrain than the other. Although marking 5* I would estimate the filling capacity is more like 750ml before spillages rather than suggested 800 ml plus, and would recommend when fixing to aerobars to use a little rubber under the Velcro strap to stop the unit sliding forward along your aero bars. The reality is this is very minor, the time saving and safety positives this products gives far outweigh any minor negatives to the hundredth degree. Final tip, missing instruction, to get your drink through the straw, gently bite on the end of it first, and ride out a few times with it before you decide to cut the straw to your fitting just so you can be sure.

Bought for Copenhagen Ironman. You can install it on the tri bars on the topside or bottom giving a better fit for your bike. Flat bottom for easy filling at the sink. Refills mid race were perfect thanks to port. It doesn’t spill if you don’t overfill it, if you do it will soak you... trim straw to ideal length.
