Research shows that using a larger chainring with a larger cog is more efficient. It is also important to have a range of larger chainrings for over geared training.
Olympus chainrings are CNC'd out of a premium 7075 aluminum that's gone through a T6 heat treatment process to create the stiffest and smoothest chainrings that can be made. In a sport where the smallest fraction of a second can mean the difference between a win or loss, this is a great upgrade to increase drivetrain efficiency.
