Compatible with Specialized thread bottles of 621ml and 710ml, it integrates seamlessly with aero bars and Speedfil’s Z4/Z4+ cages, offering rapid refills and aerodynamic efficiency to keep competitive cyclists and triathletes hydrated without losing speed or focus. ## Description The Speedfil A2 Hydration system includes a bottle but the threaded drinker section can work with any Specialized thread compatible water bottle in both 500ml & 750ml sizes. The wind tunnel developed A2 model 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 patent pending 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. Review: Excellent kit for my bike with many ways to mount ... - 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. Review: A big improvement for training rides - 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. ## Features - HIGH PERFORMANCE HYDRATION ACCESSORIES – Speedfil hydration systems and accessories are designed to meet the demands of triathlon, Ironman & cycling competition.

F2 is similar to A2 meaning it uses a standard Specialized "Purist" style bottle so you can use a different bottle if you want (larger, insulated, etc). The F1 is aero, fills the center triangle of your bike and had a large capacity. Both F1 and F2 can be used with a road bike. **Q: Does the A2 threaded cap work with Elite Fly bottles?** A: Thanks your interest in the Speedfil A2. Due to the thinner walls and different cap profile of the Elite Fly bottle we do not consider this to be compatible with the A2. If you are looking for an alternate bottle to use with the A2 a Specialized branded Wide Mouth bottle is compatible. **Q: Can one use other generic bike bottles or do you have to use the proprietary one? Trying to get a larger capacity bottle, many thanks and good racing** A: Thanks for your interest in our Speedfil products. Yes you can use other bottles as long as they have the same threads. Any Specialized brand bottle will work and you can use a 21oz bottle or the larger 24 oz. There might be a few other bottle brands out there that will work. We do know that Polar brand bottles do not fit. I hope this helps Speedfil. **Q: How do you attach the water bottle to your aerobars? Do you have to buy the Z4 cage?** A: I did buy the cage. I think there may be several renditions of a cage system for this bottle but the easiest and most highly recommended was the Z4. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Excellent kit for my bike with many ways to mount ... *by D***N on 28 September 2017* 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).

Happy with the product. ### ⭐⭐⭐ XLAB Torpedo Versa 200と比べて *by T***N on 18 June 2017* 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。 ## Frequently Bought Together - Speedfil A2 Bicycle Water Bottle, Between the Arms Hands-Free Hydration System with Refill Port - Speedfil F1 Bicycle Water Bottle, Hands-Free Frame Mounted Hydration System with Refill Port - Speedfil Z4/Z4+ Between-The-Arms (BTA) Water Bottle Cage with Computer Mount. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.hr/products/260156355-hands-free-bicycle-water-bottle-lid-and-drink-tube-adaptor](https://www.desertcart.hr/products/260156355-hands-free-bicycle-water-bottle-lid-and-drink-tube-adaptor) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-07-22*
