Collection: Number Belt

A good bib belt – also known as a race belt – is a small piece of equipment that makes a huge difference on race day. It makes it quick and easy to attach your bib without the need for safety pins, and it can be worn throughout a triathlon or used for individual runs and bike races. At Transition Zone you will find a carefully selected range of bib belts, which are designed with comfort, function and quick changes in mind. Whether you are a new triathlete, experienced runner or gravel rider, a bib belt will give you freedom and flexibility during competition.

With a number belt, you don't have to make holes in your clothes with pins, and you can easily turn the number from back to front – for example when you go from bike to run in a triathlon. This means faster changes, less stress and more focus on what counts: your race. Our selection consists of lightweight, adjustable and sweat-wicking models that fit securely – even over long distances and at high speeds.

Number belts are typically associated with triathlons, where they are a fixed part of the T1 and T2 transition. But also in regular fitness races, cycling races and adventure races, a number belt is a practical solution. You don't have to think about safety pins, and you avoid damaging your expensive running or cycling clothes. The belt is easily fastened around the waist and keeps the starting number in place without it flapping or getting in the way.

Many of the models we sell at Transition Zone are also equipped with extra features such as elastic holders for gels, reflective details or silicone inserts that prevent the belt from slipping. This makes them ideal for both short and long distances, where energy products and visibility also play a role.

Race belts are easy to adjust and can be used by both men and women. Whether you're competing in a sprint triathlon, marathon or gravel race, you'll get a belt that works – and will quickly become a permanent part of your race kit.

A running belt should not only be practical – it should also be comfortable to wear. That's why at Transition Zone we only choose models that combine low weight with high comfort. The belts are typically made of elastic materials that adapt to the body without tightening or chafing. Most have flat buckles and flexible adjustment systems that make it easy to find the right fit – even if you are wearing changing layers of clothing along the way.

The actual attachment of the starting number is usually done with elastic cords or snaps, which keep the number secure, whether you are running, cycling or sweating in the summer heat. At the same time, you can easily remove or change the number without any hassle. Several models are also washable, which is practical if you use your number belt again and again in both training and competition.

At Transition Zone, we only sell race number belts that we can vouch for ourselves. This means products that are developed for serious use – and that meet the demands you as a triathlete or runner make. In our range you will find both simple and advanced race belts, so you can choose based on your needs and your level of ambition.

Whether you need an ultra-light belt with a focus on speed and minimalism, or a model with space for gels and extra features, you'll find it here. A good number belt gives you the freedom to focus on performance and rhythm, without having to think about your starting number along the way.

We are happy to help you choose the right product – and are ready to advise on everything from placement and adjustment to use in competitions. A number belt may seem like a small detail, but it makes a big difference on the day when it all counts.
