- 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
