Product Description

The new asymmetric design of the Dura-Ace Redesigned plates that improve the contact interface with the cogs. Other improvements to the links provide greater durability and life with less noise and smoother function. Use of hollow pins drops weight by over 18 grams even with the addition of a quick connection / removal link.

Strengths:    Light, quiet, good shifting performance, link-system straightforward.

Weaknesses:    Cost

Bottom Line:

Previously used a SRAM chain, but found it a bit noisy, and never quite got perfect indexing (don't really know why).
Thought I'd give this a go, as bike shop had it in stock, and have always found that Dura-Ace was kind of a guarantee...

Strengths:    None

Weaknesses:    Breaks very easily.

Bottom Line:

The product is not very well made. The connecting link is poorly designed. The chain broke at 100 miles into a double century. It snapped the rear derailleur, the rear cassette and part of the wheel. I should have stayed with Wipperman.
