Shimano CN-7900 Dura Ace Chain (09) | $70
BikeRadar verdict
"Smooth, reliable and not too heavy either"
This all-new asymmetric Dura-Ace chain with slotted inner plates and hollow pins is pretty light, and its performance is silky smooth at all times.
The front shifting in particular felt great, and our high-speed filming showed it to be a fuss-free shift.
There’s a new tool-less QuickLink to join the chain available shortly, but you can still use the current Shimano link pin to rejoin the chain if you want.
Manufacturers description
Top of the range Dura-Ace Super narrow lightweight 10-speed directional chain for optimum cassette and chainset interaction and maximum power transfer.Chain uses a directional design with specifically shaped inner and outer plates to optimise shifting over the chainset and cassette.
* Outer plate design has been developed to reduce the chance of chain suck
* The inner plate has been developed for better contact with gears providing smoother shifting under high load, giving efficient pedalling, increased rigidity, and near silent running
* Hollow link pins and perforated inner link plates offer great weight savings
* Comes with optional SM-CN79 reusable Quick Link for easy installation and removal without the need for tools
* Hyperglide (HG) series 10-speed compatible chain
* Durability is assured through a chromising treatment on link pins, and the heat treatment of rollers, pins, and plates
* 5.88 mm chain width, optimised for 10-speed Super Narrow HG drivetrains
* Zinc-alloy silver finish offers the longest lasting and best resistance to corrosion
* 115 links
* Weight: 252 grams

User review of Shimano CN-7900 Dura Ace Chain (09)
LOL. The Shimano CN-7900 Dura Ace Chain maybe silky smooth with a Shimano cassette but DOES NOT WORK with an SRAM 11-26 Red Casette. I tried it. It bunches up on the 11t cog. I think due to Shimano's patents the SRAM cassette only has three places where the chain will change cogs, whereas Shimano has four. Be warned. :-)
