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

OVAL CHAINRING ADVANTAGES

  • 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
