Rotor QXL Inner Chainring 110BCD 4 Bolt 44T Shimano

Riders looking to lay down some serious power in the most efficient way will love the Rotor QXL Inner Chainring 110BCD 4 Bolt 44T Shimano.

Rotor were not happy to sit back once they had produced the revolutionary ovalised Q ring, instead they poured time and resources into making them better, this resulted in QXL. Ideally suited to more powerful riders who put down large watts with regular out of the saddle efforts, these are the Q rings of choice.

For this an increased ovality is required to make the most of their pedal stroke. This shape reduces the areas of negative work (dead spots) in their pedal revolution than they would get from the traditional Q ring shape.

Rotor have still maintained their highest standards for reliability. CNC machining from aircraft grade 7075 T6 anodised aluminium gives you superb shifting and perfect rotations mile after mile.

The big talking point here is the ovalisation, but do not ignore the design that is ramped and pinned for the ultimate performance. The shaping was discovered to utilise your strongest muscles, whilst compensating for weaker ones, by varying drivetrain resistance thus allowing you to save up to four seconds per kilometre - a highly significant saving.
