Shimano Ultegra 6800 - HG700 - 11 Speed 116 Link Chain
The Shimano Ultegra Chain is a super narrow lightweight 11-speed HG-EV symmetrical design chain for smooth shifts and maximum durability. The outer plate design has been developed to reduce the chance of chain suck.

Sil-Tec surface treatment technology (PTFE plating) is smooth running and increases durability. The inner plate has been developed for better contact with gears providing smoother shifting under high load, while also providing efficient pedalling, increased rigidity and near silent running.       

Key Features:

• 5.62 mm chain width, optimised for 11-speed Super Narrow HG-EV drivetrains
• Outer plate has been developed to reduce chain suck
• Sil-Tec surface treatment technology for smooth running and increased durability

Shimano Ultegra ST-R8020 for Mechanical Shift/Hydraulic Disc Brake

• Precision-engineered Ultegra STI lever with hydraulic disc brakes give you control, modulation and power with minimal effort in all riding conditions .
• Shift cables are routed under the bar tape: re-development and positioning of the internal mechanism in combination with Polymer coated cables have made this possible, providing faster, lighter and smoother shifting .
• Vivid indexing provides a constant amount of shift lever force across all 11 sprockets .
• Ergonomic shift arc follows natural hand movement with inward shift stroke distance reduced for rapid and precise gear changes .
• Hydraulic brake lever provides excellent stopping power with less effort especially from the hood position .
• Hydraulic reservoir tank provides pad to rotor clearance auto-adjust maintaining braking performance during pad wear .
• Free stroke adjustment for pad to rotor contact setting .
• Tuneable reach adjuster enables custom fitment for all hands.

Shimano Ultegra RD-R8000 Rear Derailleur

• Ultegra Shadow design rear derailleur with wide link design gives quick accurate shifts and excellent drivetrain efficiency.
• Sleek appearance with Low profile Shadow design construction reduces risk of damage in a crash.
• Wide outer link plates increase pivot joint rigidity to reduce shifting deflection.
