Frequently Asked Questions
What fits Shimano DURA-ACE Di2 REAR DERAILLEUR 12s?
On this page we list cassettes for this derailleur, shifters that drive this derailleur, chains for this derailleur. Each listing was matched on a specification we hold for both parts; anything we could not verify is omitted rather than assumed to fit.
Can I use a higher or lower speed chain with Shimano DURA-ACE Di2 REAR DERAILLEUR 12s?
No. Shimano DURA-ACE Di2 REAR DERAILLEUR 12s is a 12-speed component and needs a 12-speed chain. Chains for different speed counts have different external widths and inner-plate profiles, which causes poor shifting or interference with the neighbouring sprockets.
