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

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
