We've designed our Ultegra 8000-compatible crankset to be a perfect match for your Ultegra 8000 crankset. Precisely machined to become one solid piece together with the crankset arm, our chainring is the best solution on the market if you're looking to enhance the performance of your drivetrain without sacrificing the original looks of your crankset.

If you are considering our Ultegra 8000 chainring to replace your original chainring for other 110 BCD (4-bolt) asymmetric crankset design (Ultegra 6800 or similar), please note that our chainring has been designed to exactly match Ultegra 8000 crankset only, and it may be installed on most other 110 BCD (4-bolt) asymmetric cranksets, but the chainring arms will not be aligned properly

• 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
