Rotor QX2 BCD 104 Middle Chainring

“Shred” – you don´t usually take advice from the office recycling bin but your favorite trail begs to be ridden so you obey. QX2 chainrings for your double 104BCD cranks feature subtle 10% ovality that can be dialed in to take advantage of the most-powerful part of your pedal stroke to give you faster acceleration and better traction on whatever terrain you thrust under your wheels. QX2 offers 3 Optimum Chainring Positions (OCP), which can be adjusted to take advantage of your pedal stroke's most-productive zone to propel you forward on each rotation.
