AeroGain Straight BTA Spacer

AeroGain BTA Spacer is specifically designed to improve the aerodynamic profile for triathletes and time trialists by addressing one of the most critical areas on the bike: the cockpit. When you place your water bottle between your arms (BTA - Between The Arms), a void or inefficient airflow often occurs between the rider's arms and upper body. This 70 mm spacer acts as a bridge, raising your bottle cage to a position where it effectively closes the gap around your upper body. By minimizing turbulence in this area, total drag is significantly reduced, which is essential for achieving higher speeds with the same power output. AeroGain developed this product with a philosophy of marginal gains, where small technical adjustments accumulate into noticeable time savings on race day. Furthermore, the increased height helps keep your posture more stable, as you don't need to duck down or break your aerodynamic position to reach your hydration. This means you can maintain an aggressive and streamlined profile over longer distances, making you a faster and more efficient cyclist. This is not just a piece of plastic, but a carefully considered tool created through dialogue with experts and active riders who understand the importance of reducing air resistance in real-world competition situations, whether on a flat time trial or during the demanding conditions of a full Ironman.

The AeroGain BTA Spacer is constructed from advanced high-strength materials selected to withstand the extreme stresses professional triathlon equipment is subjected to. As evident from the product's finish, a robust manufacturing process has been employed, ensuring both low weight and extremely high structural integrity. To guarantee a secure and durable mounting, the spacer features integrated brass thread inserts, ensuring that bolts remain tight and do not loosen due to vibrations from uneven road surfaces or intense riding. This Danish performance brand prioritizes flawless performance in real-world conditions – not just in the lab. Consequently, the materials are tested to withstand the elements, including rain, sweat, and UV radiation, without losing strength or shape over time. The solid construction also ensures your water bottle remains stable even when full, preventing unwanted rattling or noise that can be distracting during training and competition. By selecting high-quality materials, AeroGain ensures riders can have full confidence in their gear, which is vital for mental focus when pushing to the limit. The brand combines engineering precision with a practical approach, resulting in a product built to last for many seasons, regardless of the mileage. This dedication to quality and durability makes AeroGain a favorite among both elite athletes and serious enthusiasts who demand the best for their triathlon bike.

Yes, this AeroGain Straight BTA Spacer is fully compatible with AeroGain's dedicated BTA system and is designed to provide seamless integration with your current setup. Although this specific model is a Straight version focusing on a stable 70 mm rise, it is part of a wider series of spacers that includes angles of 0, 10, 15, and 20 degrees, allowing the rider to fine-tune their cockpit to perfection. Mounting is made incredibly simple and user-friendly, so you can quickly install or adjust your bottle cage as needed without being a professional mechanic. The flexibility of the AeroGain system ensures it fits a wide range of different triathlon and time trial bikes, making it an extremely versatile solution. By raising the bottle cage by 70 mm, the bottle becomes easier to reach, minimizing the time spent out of your aerodynamic position when hydrating. This is a significant advantage during long races, where every movement away from the aero bars costs valuable seconds. The system is developed by ambitious athletes for ambitious athletes, meaning every detail regarding functionality and compatibility has been carefully considered. Whether you ride a specialized TT bike or a modified road bike for triathlon, the AeroGain BTA system and this spacer will help you create a more efficient and ergonomic cockpit. It offers the opportunity to optimize your performance without having to invest in an entirely new bike, making it one of the most cost-effective ways to achieve real improvements in your bike setup and overall riding experience.
