Collection: 51 Speed ​​shop

When it comes to precision, comfort and aerodynamics, 51 Speedshop is among the absolute leading brands on the market. Founded by physiotherapist and biomechanics expert Mat Steinmetz, 51 Speedshop draws on decades of experience with professional athletes, bike fitting and aero optimization. Their mission is clear: to deliver components that create the most efficient and comfortable position for triathletes and time trial riders.

At Transition Zone you will find a carefully selected range from 51 Speedshop, including arm cups, extensions and spacers – all developed with a focus on detail, function and performance. The equipment is designed to give you better support, more adjustment options and a more natural body position in aero – regardless of your level.

Arm cups from 51 Speedshop are known for their uncompromising quality and well-thought-out ergonomics. Here you don't just get a pair of elbow cups, but a precision tool to keep you stable, relaxed and aerodynamic for hours. They are available in different shapes and depths, so you can choose between maximum support or more freedom of movement, depending on your needs.

Many triathletes experience tension and fatigue in their arms, shoulders and neck after long rides – often as a result of poorly designed arm cups. 51 Speedshop addresses this problem with their well-padded and anatomically correct designs, which are developed based on hundreds of bike fits and feedback from professional athletes.

At the same time, the materials and wide surface provide even pressure distribution that prevents soreness – perfect for both training and racing. This makes arm cups from 51 Speedshop an obvious choice for anyone who takes comfort and performance seriously.

A good aerodynamic position must be efficient – but also sustainable over time. With extensions and spacers from 51 Speedshop you have the opportunity to tailor your cockpit setup with an unprecedented degree of precision. Extensions are available in several variants, both with and without ergonomic angles, so you can choose the grip that feels most natural and saves effort.

Their ergonomically curved extensions are particularly popular with triathletes who want a more relaxed and aerodynamic grip that reduces strain on the wrists and forearms. This results in better blood flow, less muscle fatigue and thus a more efficient line.

Spacers from 51 Speedshop allow you to raise or lower the arm cups and extensions exactly to your liking. This is essential to finding the balance between a low aero position and the comfort that allows you to keep up the pace all the way into T2. At Transition Zone we have several of their customization components that can be easily integrated with existing cockpit systems.

There are many cockpit components on the market, but 51 Speedshop stands out by being developed with an uncompromising approach to fit, biomechanics and quality. Each product is tested in real conditions – by both amateurs and professionals – and further developed based on concrete feedback.

This means that you as a customer get equipment that doesn't just promise something, but actually delivers in terms of comfort, function and speed.

At Transition Zone, we recommend 51 Speedshop for triathletes and time trial riders who don't want to compromise. The products are easy to install, compatible with most systems and can be adjusted down to the smallest detail. At the same time, they are made of durable materials that will last for many hours of use - in rain, sun and sweat.

Whether you're looking for a more ergonomic cockpit, want to improve your aerodynamics or just want more comfort on your bike, 51 Speedshop is an obvious choice. With their arm cups, spacers and extensions, you get a solution that takes your position and your performance to the next level – and we're ready to help you with the right setup.
