GU Flask (Holds 5 Servings)

cycling

I use this every ride, no matter hard or easy.

I use this on long runs. I usually only put two GUs in it. Unless I thin it a bit with water I have a hard time getting it out. Even then, its still hard to squeeze all the air out from the bottom to get all the GU, while running. I also dont care for the hard plastic nozzle. I feel like Im going to break my teeth when running and jamming it in my mouth. I wanted to love it since there arent many alternatives, but I just dont. At least it wasnt very expensive.

This beats the GU flask in every imaginable way. First, it has a bigger mouth, so it's easier to load, 2nd, it's soft. Really, really soft, and pliable. Not only will it not leave you with a spinal injury if you take a fall, but you can twist & wring it to get ALL of the ride fuel out of it. It's also very easy to clean, in part because of the pliable (silicone?) flask material, but also because of it's pliability, and large mouth.

Best of all though is the valve can be twisted open & closed by holding it between your teeth while squeezing, so on timed events you don't have to stop to feed. With Powerbars no longer in production, a reusable system is more important than ever. This makes the gel system workable enough you won't mind leaving bars behind.

A nice option to other flasks, well made and easy to squeeze everything out. Only complaint is the cap screws off to open valve, so you gotta pay attention. I have another with a bite valve that solves this issue, still a good product.

Purchased for gravel riding (to minimize waste and optimize gel use) but nozzle flow required concentrated pressure which distracted from riding and did not provide adequate quantity. Flow was negligible when temps were 45 deg or lower using GU roctane.

I love this dispenser, it is a little hard to clean out but it the best way to dispense your Gel. Buying the Gel by the larger container vs. the packets is really good way to save packaging, pay less for the gel and not cut your mouth on those metallic packets. Plus you can swallow a little or swallow alot and no messy packet to deal with later.

Have used several times on my training rides. I make my own GU. Issue for me is that it is not easy to use one-handed. Taking two hands presents some additional risks while cycling. Furthermore a few times the entire top rotated, vs just the spout. Thus I will continue to use on training rides but in other rides will likely continue to use the packets that I can open with my teeth.

Bought 2 of these to use for easier nutrition consumption. A great decision with no mess or trash to worry about during extending rides.

Be careful and don't over tighten! Extremely hard to get open to fill if cap is too tight. Otherwise a very good product. Very pliable and easy to squeeze. Has doseage marks. I like it better than the Hammer flask.

Other than the hard-to-loosen nozzle, the other serious downside is if you don't work thru the batch in your flask relatively fast, then the gel hardens in the flask corners and along the bottom edge. Short window to work through 5 packs' worth. So back to the individual eco-insensitive packs I go ,)
