Collection: Stem

A stem may not be the first thing that comes to mind when you think about performance and comfort on your bike – but it should be. The stem is the crucial component that connects the frame and handlebars, and its length, angle and stiffness have a direct impact on your riding position, control and aerodynamics. Whether you’re a road rider, time trial rider or triathlete, it’s important to choose a stem that matches both your body and your riding style.

At Transition Zone, we have selected stems from FSA and Zipp, both known for their quality, precision and performance. Whether you are a casual cyclist or an elite athlete, we will help you find the optimal solution to get the most out of your training and racing.

FSA (Full Speed Ahead) is one of the most respected names in the cycling world, and their stems are a great choice for riders looking for reliability, functionality, and value for money. FSA produces stems in both aluminum and carbon fiber, and offers different lengths and angles so you can easily customize your position on the bike.

A properly installed FSA stem can help adjust your saddle-to-bar distance and make it easier to find a balanced position that provides both power transfer and comfort. FSA stems are used by road riders, triathletes, and gravel enthusiasts alike – and they deliver stable, stiff connections without adding unnecessary weight.

At Transition Zone, we have carefully selected the most popular models so that you have access to tested quality, regardless of your level and bike type.

If you're looking for marginal gains and want the ultimate in lightweight and aerodynamics, Zipp is the obvious choice. Zipp stems are known for their precision construction, low weight, and elegant design, which are perfect for both race and triathlon bikes. With roots in the world of competition and close collaboration with professional riders, Zipp stems are made for riders who don't want to compromise.

A Zipp stem doesn't just allow you to adjust your riding position - it actively contributes to a more aerodynamic front end and better stiffness in your cockpit. This means better control, especially at high speed, and a feeling of direct contact with the bike. The low weight also helps keep the overall mass of the bike down - something that's especially important when you're accelerating, climbing or shaving seconds off your split times.

At Transition Zone you will find a selection of Zipp stems that match the demands of both triathletes and road riders who want the best of the best.

Choosing the right stem isn’t just about brand and material – it’s about fit. A stem that’s too long or too short, too steep or too flat can cause poor balance, overload, and reduced performance. Conversely, a properly fitted stem can improve your position, give you better comfort, and significantly increase your efficiency on the bike.

At Transition Zone, we help you find the ideal stem for your body type, bike type and ambition level. We carry stems in multiple lengths and angles so you can achieve the right reach and drop to match the rest of your cockpit – whether it’s with flat bars, basebars or aero extensions.

The stem is a small component, but it has a big impact. It connects rider and bike, and it has a direct impact on your performance – especially over longer distances or at high intensity. That’s why you should never underestimate the impact of upgrading or adjusting this part of your setup.
