Collection: Arm Cups

Arm cups – or arm pads – are one of the most underrated elements of an aerodynamic cockpit. This is where your forearms rest for hours during both training and competition, and the comfort of the arm cups can be directly critical to your ability to maintain an efficient and aero position. It’s not just about softness, but about support, stability and fit.

At Transition Zone we stock arm cups from gebioMized, Drag2Zero and AeroCoach – three of the most respected names in aerodynamic optimization and ergonomic cycling gear. Whether you’re a triathlete, time trial rider or just a position geek, you can find arm pads here that will make a real difference to your performance.

When you spend hours in an aero position, comfort is not a luxury – it’s a performance factor. Ill-fitting arm cups can lead to shoulder and neck tension, unstable posture, and, in the worst case, a reduced ability to maintain cadence and pedal pressure. That’s why brands like gebioMized have developed ergonomically shaped arm cups that follow the body’s natural structure and support in the right places.

Drag2Zero and AeroCoach offer several different shapes and sizes, so you can find the solution that best suits your position, width and forearm length. Some prefer deep cups for maximum support and comfort, while others go for lower, flatter designs for more freedom of movement. Common to all models is a focus on functionality and comfort – even when going fast.

One of the great advantages of quality arm cups is the adjustability. The best systems let you adjust the angle, width, height and length, so you can fine-tune your cockpit setup down to the millimeter. At Transition Zone, we sell, for example, Drag2Zero arm cups, which are known for their modular design and flexibility.

If you are looking for the ultimate in personal fit, gebioMized arm cups are a strong choice. Their products are developed based on bike fit analyses and used by professional riders and triathletes who place extremely high demands on both aerodynamics and comfort. With AeroCoach you get ultralight and stiff solutions that also ensure good pressure distribution – ideal for those who are chasing marginal gains over both short and long distances.

A good set of arm cups can be the final piece of the puzzle that gives you peace of mind in your position and enough stability to stay on track and focused throughout your cycling – especially in triathlons, where it's important to save energy for the race.

It can be tempting to focus on the more visible components when upgrading your bike. But often it's the small touchpoints, like arm cups, that make the biggest difference to your experience and performance. A good position is not just about aerodynamics, but also about being able to hold the position without feeling uncomfortable, shaking, or having to constantly adjust.

Arm cups from AeroCoach, Drag2Zero and gebioMized are designed with that in mind – to support your body so you can perform at your best and maintain your energy for longer. This applies both during training and competition, where every watt and every second counts.

At Transition Zone, we help you find the right arm cups for your cockpit. Whether you're looking for stiffer cups for racing or softer, more ergonomic solutions for long training sessions, we have something for you. And we know what works – because we're part of the triathlon and cycling community ourselves.
