CONTROLTECH Eccentric Chainring SRAM 53T

Eccentric Chainring for less power output and better performance : 

• Better acceleration and dynamics than round chainring
• Power output increases: 5.6% when crank arm rotation degree starts from 30 to 150 degree (Dominant leg).
• Cadence increases: 5.9 % when crank arm rotation degree starts from 210 to 330 degree (Non-dominant leg).
• Great tool to train your non-dominant leg to have greater performance.
• Compatibility: SRAM.
