Shimano CN-7900 Dura Ace Chain

Our review

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.
