Speedfill A2
The patented Speedfil A2 system works with any Specialized thread compatible water bottle in both 21 fl oz. (621 ml) and 24 fl oz. (710 ml) sizes.
The wind tunnel developed A2 is designed to be used with triathlon/TT aerobars. The A2 achieves its superior aerodynamics by it’s key location within the riders cockpit. The athlete’s arms shield the device, thus becoming invisible to the wind.
The patented Zerosplash technology virtually eliminates fluid splashing so wet and sticky handlebars are a thing of the past. The design allows for rapid refilling on the fly, hands free drinking and easy cleaning.
The A2 can be used with any standard water bottle cage and any BTA (between-the arms) mount available on the market today. Speedfil recommends using the A2 with our signature Z4/Z4+ cage for the ultimate Speedfil experience.

Used it 3 times now and everytime my bike is covered in the sticky liquid I drink because the bottle leaks in spite of being screwed in tight with both rubber rings….unfortunately can’t return it cause I’ve already cut the straws.

Had bought one of these on E-bay in the spring and after 1 or 2 uses the thin gasket sealing ring in the cap broke rendering it useless as it constantly leaked. Rolled the dice on this one as I have a Full Ironman coming up and needed the ease of drinking on the fly. Very happy to see that the new one is much improved with the sealing area molded in a larger profile and in a more durable plastic. Mounts perfectly between the Aero bars for easy hydration.

Before acquiring this product I found it difficult to maintain pace and form on training rides when having to pause to take in water. This product fixed that problem by having water available without having to reach for bottles or change positions. Water whenever i needed was a big improvement. Some minor adjustments with the straps holding the bottle and to position and steady the tube position helped cutomize for my preferences. Also fits other bottle sizes so can be changed out. Happy with the product.

I previously wrote a review and my product arrived missing a part. I emailed amazon and the manufacturer. The manufacturer emailed me in less than 24 hrs and shipped the part immediately. I was very impressed. So far the product works great with my existing holder.

Fits great on aerobars. Doesn’t splash back during refill. Also, valve opens easy.

Leaks! The elbow joint leaks, the straw leaks, the bite valve leaks. I had one for awhile and it leaked so badly it corroded my headset bearing. Bought a new setup and switched the mounting direction, and the new one leaks just as badly. I lost so much fluid on my ride and was a sticky mess. I have called and emailed and Facebook messaged this company asking for replacement parts or assistance and have received nothing at all in response. Poor customer service and a cheap product that I really wished worked. Love the way it’s mounted and the way it fills, just wish it didn’t leak. Ridiculous that they don’t even care to contact you back. Super angry!

It fits well/easy to access BUT....once you take one sip, the straw isn’t submerged in the water. Seems to only work well when it its totally full. Not efficient/you have the twist the straw in weird ways to get water. Not easy while riding.

Excellent kit for my bike with many ways to mount (bought the bar mount as well). Also makes it easy to tape CO2 cartridges and gel packs to it. Love the Garmin clip on (required slight modification to work). Does not seem to work with other bottles very well, must use the one that it comes with. I was oping to use a larger one but did not have any luck. Refilling works quite well. The velcro holds the bottle in solid. Use a large rubber band to hold the straw in perfect position while riding.

XLAB Torpedo Versa 200のボトルをレース中に落としてしまい、代替えにこちらを購入しました。形状が普通のボトルと同じため、ボトルにドリンクや水を入れて持ち運びやすいです。蓋は、スペシャライズドと同じ形状のため、スペシャの蓋を付けて持ち運んでいます。Torpedoは独特のエアロ形状の為、別ボトルでドリンクを運ぶ必要があります。トライアスロンのバイクセッティングでは、Speedfilの方が便利です。Torpedoはストローを保持するステイがボトルについているので、ストローが邪魔になりませんが、Speedfilは、これがありません。慣れれば気にならなくなりますが、結構邪魔になります。ストローからの水漏れは、どちらも似たようなものですが、Speedfilの方が多い気がします。とくに、ストローの先端からは、Speedfilはちょっとした段差のしょっくでも飛び散ります。飲み口を前後することである程度調整できますが、それでも飛び散ります。Torpedoの方が、Speedfilよりもややましで、ストローも吸いやすい形状です。ボトルの注入口からの水漏れは、どちらも似たようなものですが、Speedfilの方が多いです。一見しっかり蓋が締められるように見えますが、結構隙間が大きいのでよく漏れます。Torpedoはバルブタイプと蓋タイプの二つが附属しますが、バルブタイプは数回使用すると駄々漏れです。蓋タイプの方が簡便で漏れないと思いますので、お勧めです。総合すると、Torpedpの方がいいと思います。

I have used other hydration systems that fit between the aero bars but on a small frame, they don't always fit well. I have a small women's tri bike. This one fit perfectly, did not obstruct the grip of my hands on the bars and did not slosh liquid when going over uneven surfaces. It was easy to fill. A bit pricey for a few plastic bits and a water bottle, but it works. One suggestion would be to have a stiffer straw so it doesn't flop around. Or maybe even a way to clip it into place. I ended up using the Velcro strap that comes with it to hold the straw in place such that I can sip in aero position.

It's okay. Does a better job than some other aero bottles at keeping fluid inside but it still leaks some. It's also heavy by itself even without fluid in it. More convenient than most other refillable alternatives being interchangeable with the collection of bottles we all have. Like i said, it leas a little but not as much as the others i've had.
