Special tooth shape guarantees a tighter contact with chain and softer pedalling (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 aluminium alloy
Variable teeth thickness prevents chain dropping
Even at-the-wheel distribution of pedalling torque
Improved responsiveness and pedalling smoothness, narrower dead spots and increased span of your gluteus and hamstrings
Easier uphill riding, especially on soft and slippery terrains
Increased pedalling efficiency
