GARBARUK Oval chainring for Shimano GRX RX600-1/810-1 cranksets. 

• 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
