A new bright life for your Dura-Ace 9100 crankset

We've designed our Dura-Ace 9100-compatible crankset to be a perfect match for your DA 9100 crankset. Precisely machined to become one solid piece together with the crankset arm, our chainring is the best solution on the market if you're looking to enhance the performance of your drivetrain without sacrificing the original looks of your crankset

  • Garbaruk chainrings for Dura-Ace 9100 are located 4mm closer to the frame, thus providing the best possible chainline value

  • Special tooth shape guarantees a tighter contact with chain and softer pedaling (in comparison with regular chainrings)

  • Chamfered edges and wide mud gap keeps the ring from getting muddy

  • Increased tooth height improves chain retention while the bike is shivering and jolting

  • Overall bicycle weight reduction in the range of 150-400 grams (with no front derailleur and chainguide)

  • Manufactured using highly durable aluminum alloy

  • Variable teeth thickness prevents chain dropping


    • Even at-the-wheel distribution of pedaling torque

    • Improved responsiveness and pedaling smoothness, narrower dead spots and increased span of your gluteus and hamstrings

    • Easier uphill riding, especially on soft and slippery terrains

    • Increased pedaling efficiency


    Compatibility note

    If you are considering our Dura-Ace 9100 chainring to replace your original chainring for other 110 BCD (4-bolt) asymmetric crankset design (Ultegra 6800 or similar), please note that our chainring has been designed to exactly match Dura-Ace 9100 crankset only, and it may be installed on most other 110 BCD (4-bolt) asymmetric cranksets, but the chainring arms will not be aligned properly
