Your cart is empty.Stay hydrated with the patented Speedfil F2 system. The F2 works with any Specialized thread compatible water bottle in both 21 fl oz. (621 ml) and 24 fl oz. (710 ml) sizes. The F2 model enjoys many of the same benefits as our Speedfil F1 system but the F2 works with any standard cage mounted on the down tube. The dual splash resistant design allows the rider to refill the system on the fly. Only prime the Speedfil system once and you have access to your hydration immediately. The bite valve keeps fluid on demand without sucking up air after each drink. The F2 can be used by triathletes, mountain bikers, as well as recreational riders. For a complete hands-free solution Speedfil recommends combining the F2 system with our exclusive Speedfil Micro-Retractor (sold separately or included in the Off-Road Bundle). This retractor allows the rider to pull the drink tube up to 24 in. (61 cm) from the handlebars, drink, and then release. The retractor snaps back inside the keeper.

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.

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.

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"

great for anyone who wants nearly all to all hands free drinking while ride a road or a TT bike. the large diameter drinking tube is great for sucking down high volume. zip ties are pointless if the buyer ever wants to clean the straw, better option for anchoring the straw to the frame and handle bars is to use rubberized wire similar to Nite Ize product. it is reusable and durable.

Excellent hydration system on the bike! I love how it works with my existing cage and the top fits my other water bottles so that I can put a bigger bottle on the bike than the one supplied. I have had numerous people ask the brand and where I got it and one of my coaches was recommending it to his other trainees

I might run, cycle, and swim, but I'm not coordinated enough to drink from a regular water bottle and put it back in the cage. This thing never comes off my bike except when I clean it. My husband was so jealous that he made me buy one for him too.The only drawback is getting the straw into the sleeve. One of the metal sticks popped out which could be dangerous if it pokes you while cycling.

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.
