The chainring is one of the most important components on your bike. This is where your power is transferred to the chain and then to the rear wheel – and thus all the propulsion in your line. Whether you cycle on the road, gravel or for triathlon, the right chainring is crucial for both performance, comfort and gear shifting. A worn or incorrectly sized chainring can lead to poor gear shifting, unnecessary wear on the chain and cassette, and loss of power when it matters.

At Transition Zone, we have put together a sharp selection of chainrings that suit both the discerning road rider and the aerodynamics-obsessed triathlete. We offer chainrings in different tooth sizes, bolt circle diameters (BCD) and designs – so you can find the exact setup that suits your crankset, your legs and your measurements. We emphasize durability, functionality and low weight – and that is why we only sell quality products that meet the highest standards.

Among our selection you will find blades from Drag2Zero – a manufacturer with deep roots in the world of triathlon and time trial. Drag2Zero develops components with one thing in mind: to reduce air resistance as much as possible. Their blades are optimized to cut through the wind, so you can pedal efficiently and save watts, kilometer after kilometer.

Drag2Zero chains are typically CNC milled for maximum precision and are designed to work optimally with electronic and mechanical groupsets. They are ideal for those looking to take the next step in their pursuit of marginal gains – whether you’re racing an Ironman, 70.3 or just looking to PR your local time trial. With a variety of sizes and gearing options, it’s easy to find a configuration that matches your strength and cadence.

When choosing a new chainring, it’s important to consider both your drivetrain and your riding preferences. The number of teeth on the chainring affects how hard you pedal. A 55T chainring requires more force than a 50T, but also allows you to go faster – perfect for fast, flat routes. If you often ride in hilly terrain, a smaller chainring can give you better cadence and less strain.

You should also pay attention to the BCD – the bolt-to-bolt distance on your crankset. Not all chainrings fit all cranksets, so it’s important to choose a model that is compatible with your setup. If you have electronic gears, you should also make sure that the chainring profile is designed for precise and smooth shifting – something most of our models are optimized for.

At Transition Zone we are happy to help you find the right setup. We have tested many of the products ourselves during competition and training, so we know what works in practice. If you are in doubt, you can always contact us for guidance.

At Transition Zone you will find a selection of carefully selected blades that cover the needs of both recreational riders and elite athletes. We do not compromise on quality – so you can count on the blades we carry to deliver long-lasting durability and reliable performance. Whether you are looking for a replacement blade or need to upgrade to a more aerodynamic solution, we have the right products on the shelf.

Our range is constantly expanding, and we keep up with developments in gear components and performance optimization. When you shop with us, you don't just get access to quality products - you also get advice, fast delivery and good service from people who are passionate about triathlon and road cycling themselves.
