Description
Pair this Rotor Q Ring Inner Chainring 44T 110BCD 4 Bolt Shimano with the Q Ring Outer Chainring 110BCD 4 Bolt Shimano for the most efficient pedalling set up possible.
Rotor has become well known for their reliability and this inner Q ring is no different. CNC machined from aircraft grade 7075 T6 anodised aluminium to give 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.
