Compatible with Specialized thread bottles, it provides hands-free hydration through versatile mounting options. Lightweight and BPA-free, it’s easy to clean and built for serious cyclists seeking efficient, mess-free hydration on every ride. ## Description Speedfil Hydration Systems are continuously tested and refined for both profesional and amateur athletes who simply want to perform at their best. These inventive and patented systems deliver hydration, aerodynamics, safety and ease of use. 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. Speedfil branded hydration products are available for front, frame and rear configurations. Find the system that is right for you. ## Features - Aerodynamic/ Low Profile - Patented Zerosplash technology - No splashing on handlebars - Works with any Specialized thread compatible bottle - Hands free drinking with multiple mounting options. - Easy to clean ## Technical Specifications | Specification | Value | |---------------|-------| | Additional Features | Aerodynamic, Hands-free Drinking, Easy-clean, Zero-splash | | Age Range Description | Adult | | Asin | B005T3XZ0K | | Best Sellers Rank | #186,271 in Sports & Outdoors (See Top 100 in Sports & Outdoors) #146 in Bike Water Bottles #307 in Bike Water Bottle Cages | | Bottle Type | Standard Bottle | | Brand Name | Speedfil | | Capacity | 621 Milliliters | | Color | Bta Mount | | Container Type | Bottle | | Customer Reviews | 3.5 3.5 out of 5 stars (88) 3.5 out of 5 stars | | Included Components | A2 | | Item Dimensions W X H | 6"W x 6"H | | Item Type Name | Speedfil A2 Zero splash bottle adaptor + tubing/bitevalve (sfa200-03) | | Item Weight | 11.2 ounces | | Manufacturer | Speedfil | | Manufacturer Part Number | SF-A200-03 | | Material Type | Plastic | | Material Type Free | Bisphenol A (BPA) Free | | Model Name | A2 | | Model Number | SF-A200-03 | | Number Of Items | 1 | | Number Of Packs | 1 | | Product Care Instructions | Hand Wash Only | | Recommended Uses For Product | Biking | | Reusability | Reusable | | Shape | Round | | Specific Uses For Product | Triathlon, Time-trial | | Sport Type | Cycling | | Style Name | A2 Adapter | | Theme | Sport | | Unit Count | 1.0 Count | | Upc | 858712003013 | ## Product Details - **Bottle Type:** Standard Bottle - **Brand:** Speedfil - **Capacity:** 621 Milliliters - **Color:** Bta Mount - **Material:** Plastic ## Images ![A2 Bicycle Water Bottle, Between the Arms Hands-Free Hydration System with Refill Port - Image 1](https://m.media-amazon.com/images/I/61ENABmqYcL.jpg) ![A2 Bicycle Water Bottle, Between the Arms Hands-Free Hydration System with Refill Port - Image 2](https://m.media-amazon.com/images/I/6181ArdttJL.jpg) ![A2 Bicycle Water Bottle, Between the Arms Hands-Free Hydration System with Refill Port - Image 3](https://m.media-amazon.com/images/I/716-dGRZCNL.jpg) ![A2 Bicycle Water Bottle, Between the Arms Hands-Free Hydration System with Refill Port - Image 4](https://m.media-amazon.com/images/I/519N59ElgzL.jpg) ![A2 Bicycle Water Bottle, Between the Arms Hands-Free Hydration System with Refill Port - Image 5](https://m.media-amazon.com/images/I/81IW7pwpu9L.jpg) ## Available Options This product comes in different **Style** options. ## Questions & Answers **Q: Is there a speedfil system bottle you can attach to bike if you dont have aero bars?** A: Yes, you will want to get either the F1 or F2 system depending on your preference. 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 on Reviewed in the United States September 28, 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). 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. ### ⭐ Defective from the start *by on Reviewed in the United States May 9, 2026* Zero stars the elbow leaks immediately ### ⭐⭐⭐⭐⭐ Great product *by on Reviewed in the United States December 4, 2020* Fits great on aerobars. Doesn’t splash back during refill. Also, valve opens easy. ## 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.uy/products/6012597-a2-bicycle-water-bottle-between-the-arms-hands-free-hydration](https://www.desertcart.uy/products/6012597-a2-bicycle-water-bottle-between-the-arms-hands-free-hydration) --- *Product available on Desertcart Uruguay* *Store origin: UY* *Last updated: 2026-06-02*
