INFORMATION

Precision-engineered for performance and reliability, the advanced ALUGEAR Thread Mount chainring delivers an exceptional balance of strength, lightweight design, and superior chain control

Featuring our signature narrow-wide tooth profile, each chainring ensures secure chain retention and smooth drivetrain operation. The self-cleaning tooth design prevents debris buildup and enhances drivetrain longevity, even in the harshest riding conditions

CNC-machined from aerospace-grade 7075-T6 aluminum and anodized for maximum surface durability, ALUGEAR Thread Mount chainrings combine exceptional wear resistance with a premium finish and refined tactile feel

The thread-mount interface provides the most rigid and secure connection without adding unnecessary weight, making it the ultimate choice for serious riders seeking uncompromising performance

Available in sizes from 32T to 62T, this range allows for precise drivetrain tuning, whether you’re building a lightweight road setup or preparing for long-distance gravel marathons

The 32T - 36T versions are ideal for riders with lower power output or those using power meters that require compact gearing. The larger 54T - 62T sizes are a unique choice for Time Trial and Triathlon applications

If you seek a chainring that blends cutting-edge engineering with distinctive ALUGEAR design - this is it. No compromises

We do not offer an Oval version of this chainring. The specific Power Meter this chainring is designed for is not optimized to work accurately with oval chainrings. Using an oval chainring with this type of power meter may result in inaccurate power readings, including incorrect peaks and averaged values. For riders who rely on precise training data, a round chainring is the best choice

RECOMMENDATIONS

To ensure optimal performance and longevity of your drivetrain, we recommend the following best practices when using ALUGEAR chainrings: 

• Keep your drivetrain clean:
  Dirt and grime buildup can negatively affect shifting precision. A dirty rear derailleur, cassette, or hub may block the smooth operation of your entire drivetrain, leading to chain drops or other unwanted issues 

• Always install a new chain with a new chainring:
  A worn chain can accelerate chainring wear and cause poor engagement. For the best performance and smoothest ride, pair your new ALUGEAR chainring with a fresh, properly sized chain 

• Use a well-lubricated chain on every ride:
  A clean and well-lubricated chain significantly improves drivetrain efficiency, reduces wear, and minimizes noise, especially in harsh conditions like mud or dust 

By following these simple guidelines, you’ll maximize the lifespan of your ALUGEAR chainring and enjoy precise, quiet, and reliable drivetrain performance on every ride
