BBB Bolts For Chainrings - Double Crankset

When it comes to cycling, few components have as big an impact on your efficiency and experience as your chainrings. They are what transfer the power from your legs to the drivetrain, which is why it is crucial that your chainrings fit both your bike and your riding style. With us, you will find a careful selection of chainrings from, among others, Drag2Zero and Shimano – two manufacturers that each stand for their own approach to efficiency, durability and aerodynamics. Whether you ride triathlon, road or gravel, a correctly configured chainring setup can be the difference between a good and an excellent ride. It is not only about the number of teeth, but also about gearing, material, shape and stiffness – all factors that affect your cadence, your output and your comfort.

When choosing chainrings, it’s important to consider your level, your routes and your overall setup. A larger front chainring (e.g. with many teeth) requires more watts but gives you more speed, while a smaller chainring gives you easier gearing and a higher cadence – especially uphill. Many riders choose compact setups for hilly routes and more aggressive, aerodynamic setups for time trials or triathlons. In addition, the number of chainrings in the front (single vs. double) plays a role, depending on whether you’re riding a 1x or 2x setup. Shimano is known for its precise mechanical performance and long-lasting quality, while Drag2Zero brings innovation and aerodynamic finesse to their solutions – especially for the serious triathlete chasing marginal gains. The right gear ratio also depends on your rear wheel and cassette choice, so it’s a good idea to think of it as a total transmission, where the chainring is the foundation for how you pedal and perform.

Although many people see the chainring as a static component, it is actually a part of the bike that both wears out and can be upgraded with great effect. Worn chainrings can cause poor shifting performance, chain skipping and inefficient threading – which is why it is important to check the teeth regularly, especially if you cycle a lot or ride in wet and dirty conditions. Replacing with new chainrings can give an almost new drivetrain feel and extend the life of both the chain and cassette. Many people also choose to upgrade their chainrings as part of a larger gear optimization or to save weight, improve aerodynamics or adapt gearing to new races and goals. With the right chainrings for your bike type and purpose, you can have a more efficient, comfortable and precise riding experience – and this applies regardless of whether you are new to the saddle or an experienced watt nerd. We carry chainrings from the best in the industry and are happy to help you find the setup that is perfect for you.
