Item for sale osymetric ergo aerosymetric bcd110mm 4 bolts 54t aero outer bicycle chainring description scientifically proven technology that enables athletes to ride harder, longer and faster with less fatigue. By increasing the size of the gear when you push the hardest (downward stroke) and then decreasing the size of the gear to get through top and bottom dead zones quickly. This patented curve enables the force on the pedals to be constantly proportional to the muscular force of the rider. The chain rings varying diameter alters the effective gear ratio though out the pedal stroke, producing a higher gear on the downstroke when the rider has more power and then reducing the gear on the upstroke. The ovalization factor is extreme, a 54 tooth ring equates to pushing a 56 tooth ring on the down stroke and a mere 50 tooth at the “dead spot” this translates to up to a 10% increase in power output which can result in up to a 3% increase in speed! Specifications benefits: up to 10% more power up to 3 % more speed up to 12% less lactic acid build up!
