Shimano Dura Ace CN-HG901-11 (11Speed)
$85.00 CAD
The Smooth Link.
The CN-HG901-11 is a directional chain that utilizes Shimano's advanced SIL-TEC surface treatment on both the roller links and the pin links. This ultra-low friction fluorine coating doesn't just make the chain run quieter; it also sheds mud and grime more effectively and increases the chain's wear life significantly compared to standard zinc-plated chains. It is the definitive choice for riders who want their drivetrain to feel "new" for as long as possible.
Why the HG901 is the Gold Standard Chain:
-
Full SIL-TEC Treatment: Unlike lower-tier chains that only coat specific parts, the HG901 features SIL-TEC on all contact surfaces. This results in 60% less friction and a 20% increase in durability over standard plating.
-
HG-X11 Directional Design: The outer and inner plates are shaped differently to optimize shifting performance under load. This design ensures that the chain "grabs" the next gear instantly, providing the lightning-fast response that Dura-Ace is known for.
-
Hollow Pin Construction: To save every possible gram without sacrificing strength, the HG901 utilizes hollow pins. This brings the weight down to approximately 247g (114 links), making it one of the lightest high-performance chains available.
-
Cross-Discipline Versatility: While it's the stock chain for Dura-Ace road bikes, it is equally at home on XTR mountain bikes and GRX gravel builds, providing the same elite performance regardless of the terrain.
-
E-Bike Rated: The high-strength construction is robust enough to handle the high torque of Shimano STEPS e-bike systems, making it a reliable choice for premium electric assist bikes.
-
Quick-Link Included: Modern versions ship with the SM-CN900 Quick-Link, allowing for tool-free installation and easy removal for deep cleaning.

The Alegro Perspective: In our service center, we always recommend the HG901 as a "performance insurance policy." A chain is the cheapest part of your drivetrain but has the biggest impact on how it feels. Pairing this with Dura-Ace R9100 or GRX RX815 components ensures you're getting the exact shift quality the engineers intended. It's the quietest and smoothest chain Shimano has ever made for the 11Speed era.
