  Steel and Ceramic Bottom Brackets: Durability and Performance for All Cyclists

  Welcome to our category dedicated to steel and ceramic bottom brackets. We have carefully organized our products to help you make the right choice, based on material type (steel or ceramic) and your bike's frame standard. Before selecting your bottom bracket, make sure you know your frame standard. This will allow you to choose the perfect bottom bracket for your crankset, compatible with its spindle (24 mm, 30 mm, GXP, or DUB). Our selection includes steel and ceramic models from the renowned brands Rotor and CyclingCeramic.

  Steel Bottom Brackets: Durable and Affordable (35 to 100€)

  Steel bottom brackets are ideal for cyclists on a budget, offering good durability and solid performance. Their robustness makes them a reliable option for those looking for a quality solution without breaking the bank. They are especially suitable for everyday use and various road conditions.

  Ceramic Bottom Brackets: Smoother and Superior Performance (120 to 200€)

  For cyclists seeking optimal performance, ceramic bottom brackets are the ideal solution. These brackets provide smoother rotation, reducing friction and offering up to 2 watts of efficiency gain, particularly with press-fit models. If you frequently replace your steel bottom bracket or wish to eliminate friction noise, ceramic is a smart choice for extended longevity and consistent performance.

  How to Choose Between a Steel or Ceramic Bottom Bracket?

  • Opt for a steel bottom bracket if you are on a budget or need a simple, robust solution.
  • Choose a ceramic bottom bracket if your steel bracket lacks smoothness, requires frequent replacements, or if you want to maximize your cycling efficiency.

  Benefits of Ceramic Bottom Brackets

  • Improved smoothness, reducing friction.
  • Extended lifespan, even in demanding conditions.
  • Potential performance gains, especially for press-fit models.

  Maintenance and Longevity of Bottom Brackets

  All our bottom brackets can be maintained to ensure maximum longevity. Clean, grease, and regularly check your bracket to maintain smooth rotation and optimal performance on every ride.

  A Tested and Approved Selection

  We test all our products and consider cyclist feedback to offer you a complete range of steel and ceramic bottom brackets, compatible with all frame standards on the market. Whether you ride with a Shimano, Rotor, or Sram crankset, you will find the ideal bottom bracket to improve your comfort and performance.

  Explore our selection and choose the bottom bracket that meets your needs, for an optimized riding experience on every ride.

  Derailleur cages improve chain stability and reduce friction for smoother and faster gear changes. Our derailleur cages, including carbon models with CyclingCeramic bearings, offer reduced weight and superior durability, ideal for competitors and performance enthusiasts.

  Chains

  Our chains are categorized by brand – SRAM, Shimano, Campagnolo – and by number of speeds. They are suitable for road, gravel, and MTB transmissions. The range also includes chains treated by CyclingCeramic for enhanced efficiency from the very first kilometers, ensuring a smoother transmission and greater durability.

  Cassettes

  Our selection of cassettes mainly includes Rotor models with 11, 12, and 13 speeds. These cassettes offer a remarkable weight savings compared to standard cassettes while providing gearing options suitable for every type of terrain, whether in the mountains or on flat ground.

  Derailleur Pulleys

  Often overlooked, derailleur pulleys can significantly improve the efficiency of your transmission. Our aluminum pulleys with ceramic bearings ensure low rolling resistance, maximizing your pedaling power and extending your chain's lifespan.

  Bearings

  Our bearings are available individually or in kits for bicycle wheels, with a wide range of ceramic bearings. Designed to offer optimal efficiency and extended durability, our bearings withstand harsh conditions (mud, rain, heat) and ensure exceptional smoothness.

  By choosing quality transmission components, you maximize not only your bike’s performance but also your enjoyment of riding. Explore our full range of cages, chains, cassettes, pulleys, and bearings, and make each pedal stroke a step closer to your goals. Our experts are available to advise you and guide you to the best options for optimizing your bike’s transmission.
