Item # RTR000P

Spinning 'round.

Just as Rotor has extended its line of ovalized rings to include mountain bike-compatible rings, it has added to its quiver of round rings with the new non-Q RX2 mountain bike rings. The RX2 Outer Chainring was designed in an identical manner as Rotor's Q-rings, without the ovalized shaping.

While some riders fall in love with Rotor's ovalized rings and feel that they assist with a more efficient pedal stroke, others find that they are more comfortable on a traditional round ring. Rotor wants to give its riders a full line of choices, which is why the RX2 features a round profile, was CNC machined from 7075-T6 aluminum, and features stainless steel pins. The chainring is designed as the outer ring in a double ring setup, and it's compatible with the Rotor REX 3.2 crankarms.

The Rotor RX2 Outer Chainring comes in a 110mm bolt circle diameter, and in 36t, 38t, 39t, and 40t configurations. They are available in Black with etched logos.

This chainring is 5 hole 110 bcd so will it fit standard compact road cranks. The tech specs imply it is specific to the REX 3.2 crankset
