Which cranks is this Rotor chainring compatible with?

This chainring is compatible with Shimano 4-arm cranks for 11 and 12-speed drivetrains. It is also compatible with Rotor 4-arm spiders, the Rotor aero 4-arm spider, and the Inspider power meter spider.

What gearing options are available for this model?

The available gearing options for this model include 42 and 44 for the small chainring, and 54, 55, 56, and 58 teeth for the large chainring. These larger chainrings are particularly suited for time trial or triathlon use, as they provide maximum efficiency in the middle of the cassette range.

Can the chainline be adjusted with this chainring?

Yes, the chainring comes with a very thin spacer, allowing slight adjustments to the chainline for Shimano 12-speed crank setups.

What if my derailleur cannot rise high enough for this chainring?

If your derailleur hanger cannot rise high enough, you can use a Rotor derailleur hanger extension to ensure proper operation.

Is this chainring suitable for time trials and triathlon competitions?

Yes, the larger tooth sizes (54 to 58 teeth) of this aero chainring are ideal for time trials and triathlon races, providing maximum efficiency on flat terrain.

What materials are used for this Rotor chainring?

This chainring is made from CNC-machined aluminum, ensuring excellent stiffness and long-lasting durability.

Does this chainring fit on my Ultegra R8150 12-speed crankset?

Yes, it is fully compatible without modification. The chainring can be mounted with standard bolts or with the Rotor cover kit for the R8150, both of which are available in the Rotor accessories section on our site.

Can I install larger chainrings than 52/36 on an Ultegra 8150 12-speed crankset?

Yes, this product is specifically designed to address this limitation, as Shimano restricts Ultegra cranks to a maximum of 52/36 teeth. With this chainring, you can install sizes up to 58 teeth.
