Speedfil F2 Bicycle Water Bottle Hands-Free All Purpose Hydration System with Refill Port (F2)

This saved me on my Ironman 70.3. As someone who is terrible at riding with one hand and grabbing my water bottle, this was a gamechanger. I didn't want to get the bigger size as I still wanted to keep the water bottle cages on my bike so this was a fine compromise. I will say though - make sure your water bottle cage is the right size for this bottle before your ride or race. The race was the first time I used it and because I have a open water bottle cage - it sometimes would pop out if I hit a bump and dangle. Luckily because the tube was strapped down, it wasn't too bad and I just popped it back in. This is a pricey bottle and I think it came be done as a DIY. But if you rather have convenience - I recommend biting the bullet and getting it. Not too bad to clean, installing it was easy - I did it the morning of my race in 10 minutes by myself.

This system is a bit pricey but works great.

I used this on a 55 mile bike ride today and have to say that it surpassed my expectations. I love not having to fumble around for a water bottle out of the cage attached to my bike or the ones on my aero wings. I found that I am more consistent at taking in liquid throughout the ride. Simply bite down on the mouthpiece and boom...I am hydrated! Love it, love it! The best thing about this bottle though is the ability to quickly refill by inserting a full bottle to the quick cap and squeeze! Nothing to remove and can be done while riding. The kit comes with a plastic tube that is extra long and can be trimmed to fit. I found the quality to be high and worth the price.

This saved my life on the bike. I decided buy a bike and race a Half Ironman Triathlon (bike is 56 miles) in the span of about 6 months, most of which was over the winter. In the 5 or 6 outside rides I was able to do, I was definitely not comfortable enough to take my hands off the handle bars and drink from a water bottle. I found this device, and it really helped. I put the bottle in my back water bottle holder, and I use the velcro straps to run the tubing along my top bar. The spout comes out between my handle bars. It is very easy to put on and take off. I am able to lean forward and drink without taking my eyes off the road or my hands off the handle bars. I don't usually use the speedfill function during training sessions, but it was very helpful during the race. It saved a lot of time when I needed to refill the bottle at the aid station. Cleaning the hose can be annoying. I have a hose cleaning brush for my hiking hydration pack that works well, but cleaning without any brush would be hard. Overall, I definitely recommend this product.

Overall the product is a fantastic idea, use a standard water bottle and fit a straw up so you can easily drink when riding a triathlon bike in the aero position. Unfortunately, the product falls short, as if you try and fit any other standard water bottle to the top, they don't fit, as the threading is different "specialized"

Super convenient and easy to refill. However, it is very small. I run out on a 31 mile ride even with an extra refill from a full-sized water bottle.

Despite how difficult it was to put this together, the bottle itself works fabulous. I don't have aero bars and did a 70.3 in Georgia and it was very hot.

The bottle itself it small, so I can see the need for the "rapid refill". The threading on the cap doesn't fit my normal water bottle so I can't swap it over. It would have been nice if the tube came with the sleeve/cover already on it... it was a PITA to get on. It takes quite a bit of sucking with the long tube to get water up, but it seems to hold it in the tube if you stop drinking and release the valve before air and gravity put it back in the bottle. Overall, not horrible. It'll take some tweaking and it'll never be perfect.

When I received the speedfil F2 aero bottle system the end of March 2024 I took it out of the packaging and washed it all as it had a slight odour to it. I then set it aside and tried to use it for the first time this past weekend on my first long ride. I had to throw out all my water as it tasted and smelled like oil. I brought it home and rewashed it all again filled the bottle with fresh water and let it sit for 30 minutes and tried a drink again, it was absolutely disgusting. It both smells and tastes of oil. I tried a different bottle with the drinking hose and lid and the water again was undrinkable. It seems whatever the hose is made of is polluting the water. Sadly disappointed as I was looking forward to using this for my long training rides and my upcoming 1/2 swim/bike. Also the wire is poking out of the base of the black material. Unfortunately I am also way past my return window so I am stuck with a $95 dud.

This is a great system. It saves me from reaching down to grab a water bottle. My only complaint is that the tube doesn't always stay in its spot. There is a wire that runs along the tube that keeps it fairly steady but it isn't strong enough to keep it exactly where I want it.
