Compatibility

Shimano ULTEGRA CRANKSET 2X12s is a Shimano crankset. It is a 12-speed component. Everything listed below was matched on a specification we hold for both parts: the interface each pairing actually depends on, such as freehub body, speed count, actuation or mounting standard. Where we could not verify that interface, the part is left out rather than assumed to fit.

Frequently Asked Questions

What fits Shimano ULTEGRA CRANKSET 2X12s?

On this page we list chainrings that fit this crankset, front derailleurs for this crankset, bottom brackets for this crankset, chains for this crankset. 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 ULTEGRA CRANKSET 2X12s?

No. Shimano ULTEGRA CRANKSET 2X12s 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.
