The orientation of the oval is positioned differently for the inner and the outer ring because each ring serves a different purpose: inner for climbing and outer for time trialing or sprinting. We changed the orientation for the inner as your geometry, body position and pedaling changes when you are climbing (front wheel is up). OCP settings changes: hardest part of the pedal stroke per each setting; measured in degrees below 3 o’clock. Most studies show that we generate the most amount of power about 18 below 3 o’clock. Setting # #1….. 08 for the 53t….. 13 for the 40t #2….. 13 for the 53t….. 18 for the 40t #3….. 18 for the 53t….. 23 for the 40t #4….. 23 for the 53t….. 28 for the 40t #5….. 28 for the 53t…..
