GARBARUK CHAINRING FEATURES

  • 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

GARBARUK DIRECT MOUNT CHAINRING ADVANTAGES

  • You save bike weight by not using crankset spider and you can opt for the chainring with an appropriate specs for your drivetrain
