  Rotor Vegast

  Vegast Crankset – Versatility, Durability, and Modular Performance

  The Rotor Vegast crankset is a versatile, robust, and affordable model designed to meet the needs of all cyclists, whether beginners or experienced riders. Made from forged aluminum, it guarantees excellent durability with minimal weight, making it ideal for road rides, long distances, as well as gravel or time trials (TT). The Vegast is also an excellent introduction to Rotor's modular range, allowing you to configure cranksets tailored to various uses and disciplines.

  Uses of the Vegast Crankset

  The Rotor Vegast crankset allows you to build different types of cranksets, modular according to your specific needs and discipline. With compatibility for both 24 mm and 30 mm axles, you can customize your crankset for gravel, road, track, or TT use.

  • Classic Chainrings: The 50/34, 52/36, 53/39, and 54/39 configurations are among the most popular, offering an excellent balance between performance and versatility for road cyclists. These chainring combinations are perfect for riders looking for a high-performance crankset suitable for various situations.
  • Aero Versions: For speed and aerodynamic performance enthusiasts, Vegast offers specific configurations with 54/42, 55/42, 56/44, and 58/44 chainrings. These versions provide enhanced aerodynamics, ideal for flat terrain racing and TT or triathlon competitions.
  • Micro-Compact: The Vegast also supports the 46/30 and 48/32 configurations, which are perfect for mountainous routes and long climbs.
  • Single Chainring: The Vegast crankset is compatible with single chainring setups for both road and TT, simplifying the drivetrain and offering optimal cadence.
  • Track and Gravel: With the option for an offset axle, available in both 24 mm and 30 mm, the Vegast is also perfectly suited for gravel configurations. On the track, its rigidity allows for efficient power transfer and excellent responsiveness.

  Limitations Compared to Aldhu

  The Rotor Vegast stands out for its versatility and affordability, but it does have a slight limitation compared to the Aldhu crankset in terms of available crank arm lengths. Unlike the Aldhu, specific lengths (150 mm, 155 mm, 160 mm, and 167.5 mm) are not available on the Vegast. The Vegast focuses on standard crank arm lengths: 165 mm, 170 mm, 172.5 mm, and 175 mm, which cover the needs of most cyclists.

  Which Bottom Bracket to Pair with a Vegast Crankset?

  For pairing with the Vegast crankset, it is often recommended to use a Rotor steel bottom bracket, which offers an excellent quality-to-price ratio and enhanced durability. For those seeking superior performance, a ceramic bottom bracket paired with a 30 mm axle is an ideal option, providing weight savings and improved drivetrain smoothness.

  Key Features of the Vegast Crankset

  • Forged aluminum for maximum strength.
  • Available crank arm lengths: 165 mm, 170 mm, 172.5 mm, and 175 mm.
  • Compatibility with 24 mm and 30 mm axles, with the option for offset axles for gravel setups.
  • Classic chainring configurations: 50/34, 52/36, 53/39, and 54/39, perfect for versatile road use.
  • Aero configurations: 54/42, 55/42, 56/44, and 58/44 for improved aerodynamics in TT or triathlon.
  • Micro-compact versions (46/30 and 48/32) for mountainous routes.
  • Compatible with single chainring setups for road and TT.

  The Rotor Vegast crankset is a versatile and affordable solution for cyclists looking to enjoy the modularity and performance of the Rotor range while maintaining a competitive price. It adapts to a wide variety of uses, whether on the road, in gravel, or for aero disciplines.

These cranksets come in various configurations to meet the demands of discerning cyclists, whether on the road, in time trials, triathlons, gravel riding, or track cycling.

  Available Configurations:

  Classic Cranksets: The 50/34, 52/36, 53/39, and 54/39 configurations are perfect for versatile road use.

  Aero Cranksets: For speed enthusiasts, the 54/42, 55/42, 56/44, and 58/44 versions provide optimized aerodynamics for time trials and triathlons.

  Micro-Compact Cranksets: The 46/30 and 48/32 versions are ideal for mountainous routes, allowing for smooth pedaling during long climbs.

  Single Chainring Cranksets: Single chainring configurations with options ranging from 40 to 54 teeth are perfectly suited for road, time trials, gravel, or even track competitions.

  Specific Uses:

  Track: Versions ranging from 46 to 56 teeth are ideal for track cyclists looking for an ultra-rigid and lightweight crankset to maximize power transfer.

  Gravel: Thanks to the ability to install a 30 mm offset axle, the Aldhu Carbon crankset is also an excellent option for gravel. The offset axle allows for better compatibility with gravel frames while maintaining a high level of stiffness and performance, even on rough terrain.

  Round or Ovalized (Qrings):

  All Aldhu Carbon chainrings are available in round or ovalized (Qrings) versions, with a maximum of 56 teeth for ovalized versions. These chainrings help optimize your pedaling according to your preferences and riding style.

  Compatibility and Modularity:

  The Aldhu Carbon crankset is only available with a 30 mm axle, ensuring maximum stiffness. The crank arms come in various lengths: 155 mm, 165 mm, 170 mm, 172.5 mm, and 175 mm. This crankset is fully modular, allowing for easy component changes. If you already own a Rotor Vegast or Aldhu 30 mm crankset, you can replace the crank arms in seconds with Aldhu Carbon arms to enhance your bike's overall performance.

  Bottom Bracket Recommendation:

  We strongly recommend using a ceramic bottom bracket to maximize the performance of the Aldhu Carbon crankset. The carbon crank arms provide significant weight and stiffness gains, which could be reduced by using low-efficiency steel bottom brackets. This is particularly true for 30 mm bottom brackets, where precise installation and technical expertise are required for optimal performance. All bottom brackets in our catalog have been tested and validated to ensure perfect compatibility with the Aldhu Carbon and other Rotor 30 mm cranksets.

  Performance and Experience:

  The Aldhu Carbon crankset has been used by several professional teams and has won stages in the Grand Tours. Its lightweight design (250 g for a pair of crank arms) places it among the lightest and most performant cranksets on the market. For comparison, the Aldhu 30 mm crank arms weigh 350 g, and the Vegast 30 mm crank arms weigh 380 g. This crankset is also compatible with the Inspider power meter, providing cyclists with a complete solution for monitoring and analyzing their performance.

  Key Highlights:

  • Classic cranksets: 50/34, 52/36, 53/39, 54/39
  • Aero cranksets: 54/42, 55/42, 56/44, 58/44
