Collection: Profile Design

Profile Design is one of the most recognized manufacturers of cockpit components for triathlon and time trial. For decades, the brand has been a first-mover in aerodynamic solutions and customizable handlebar and extension systems that allow riders to find the perfect position. At Transition Zone, you will find a strong selection of Profile Design products that can help you become both faster and more comfortable – whether you are racing your first triathlon or are an experienced Ironman competitor.

What sets Profile Design apart from many others is the flexibility of the setup. Regardless of body type and riding style, with the right components you can put together a cockpit that matches your exact needs. That's why Profile Design is also the preferred choice for many bike fitters who work to find millimeter-precise solutions for riders of all levels.

At Profile Design you can build your own cockpit from scratch – and customize it step by step. Their extensions are available in different shapes (J-bend, S-bend, race, ergo etc.) and materials (aluminum or carbon), so you get exactly the hand position that best suits your needs. At the same time, the brand offers a wide selection of basebars, brackets, armpads and spacers, so you can adjust both height, width and reach.

This means you're never locked into one solution. You can experiment with small adjustments and find the exact setup that balances comfort, aerodynamics and stability. Especially for triathletes and time trial riders who spend many hours in the saddle, it's a huge advantage that everything can be fine-tuned without compromising stiffness or safety.

In addition to cockpit components, Profile Design is also known for their smart and aerodynamic hydration solutions. This includes bottle systems that mount between extensions, behind the saddle or on the top tube – all designed with a focus on low wind resistance and easy access during races. Their bottles and mounts are developed in collaboration with top athletes and tested in wind tunnels to ensure optimal performance.

Profile Design also offers a number of smaller but important parts that contribute to the overall experience: arm pads in different thicknesses, adjustable brackets, adapters and spacer kits, which allow you to tailor your cockpit down to the smallest detail. For you as a triathlete, this means you can focus on your training and your race – and not on whether the equipment fits.

In triathlons and time trials, your position is one of the most important things. It’s not just about being aero – it’s about being able to maintain an aero position for hours without losing power, comfort or control. Profile Design was created with that in mind. It’s a brand for riders who want to tinker with their setup and tweak until everything works.

At Transition Zone, we recommend Profile Design to anyone who cares about their position and wants a cockpit that can be adjusted exactly to their body and riding style. We use the products ourselves and have experience with setup and adjustment – and we are happy to help you, whether you need to build from scratch or just need the last 5 mm spacer.
