ST-5510

RD-5501-GS

Compatible with 9 or 8-Speed cassettes

Rear derailleurs are designed to the same precise 9-speed specifications as Dura-Ace, and can also be used with 8-speed cassettes.

Long-Life Pulleys

The use of larger 11-tooth pulleys results in alternating chain link contact to reduce abrasion and pulley wear. Ultegra derailleur uses a low-friction ceramic bushing in the guide pulley, and ball bearing in the tension pulley to increase pulley durability.

• Advanced Light Action / Light and precise shifting action regardless of derailleur position.
• Zytel* Resin Pulleys / Tough resilient Zytel* resin pulleys resist wear and reduce chain noise. (Zytel is a trademark of Dupont Corporation).

FC-5502

Advanced Hollowtech Design

Hollow Duraluminum crank arm forging results in increased rigidity with reduced weight.

OctaLink Oversize Bottom Bracket Axle

Large 22mm diameter hollow pipe billet axle reduces weight. Splined ends provide a more rigid, non-loosening crank assembly.

• SG-X Chain Rings / Designed to maintain front SIS shifting performance with the super-narrow 9-speed chain.

FC-5505

Advanced Hollowtech Design

Hollow Duraluminum crank arm forging results in increased rigidity with reduced weight.

OctaLink Oversize Bottom Bracket Axle

Large 22mm diameter hollow pipe billet axle reduces weight. Splined ends provide a more rigid, non-loosening crank assembly.

• SG-X Chain Rings / Designed to maintain front SIS shifting performance with the super-narrow 9-speed chain.

BR-5501

Compact Dual-Pivot Design

Dual-pivot construction provides increased leverage from more compact caliper arms while improving braking response.

Lightweight Construction

Unnecessary mass has been strategically eliminated to provide maximum strength at minimum weight.

Compact Cartridge Brake Shoe

Compact cartridge type brake shoe and holder have the same dimensions as Dura-Ace.

CS-HG70-9

Smooth Shifting 9-Speed HG Sprocket Design

9-speed performance from precision HG sprockets and super-narrow chain. No increase in cassette width allows retrofit to 8-speed freehubs.

Light Alloy Sprocket Carriers

The Ultegra cassette sprockets (CS-6500) use a light alloy sprocket carrier to mount the three lowest gears. Reduced weight, increased rigidity, and better shifting result.

Lightweight Design

The light alloy sprocket carrier(CS-6500)and drilled out sprockets result in a 9-speed sprocket cluster that actually weighs less than the previous 8-speed.

• Total Interchangeability / The use of identical drive train specifications allows complete interchangeability between 105, Ultegra, and Dura-Ace components.

HB-5501

Labyrinth & Contact Sealing

Labyrinth and low-friction contact seals effectively shut out water, mud and dirt without affecting rotational smoothness.

Borozon Treated Bearing Races

Super-mirror finish bearing races reduce friction and provide a more precise bearing action.

FH-5501

Labyrinth & Contact Sealing

Labyrinth and low-friction contact seals effectively shut out water, mud and dirt without affecting rotational smoothness.

Borozon Treated Bearing Races

Super-mirror finish bearing races reduce friction and provide a more precise bearing action.

CN-HG73

Precision Construction

Ultra-precision construction maintains strength, dependability and shifting performance on the narrower 9-speed sprocket cluster.

Improved Durability

Pin pull-out resistance increased by 50%.
