10% less Lactic Acid and 5% free power why would you say no?
The drop in Lactic Acid and extra power, all delivered smoothly to the back wheel has meant PB after PB since I have been running these. My 53t outer acts like a 56t in the power phase of my stroke and then 50t through the dead spot so I'm much quicker overall.
