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
