    BURGTEC THICK-THIN RACE FACE CINC DIRECT MOUNT CHAINRING

    The BURGTEC THICK-THIN RACE FACE CINC DIRECT MOUNT SPROCKET offers the mechanical advantage of increased drivetrain. Through extensive testing of different prototypes with varying amounts of ovality it was found that 115% (from center to top) is optimal. This adequately reduced dead center and gave the same perfect chain retention and silence as the round chainrings. Shortening the dead center at the top and bottom of the power curve allows you to return to the power phase of crank rotation earlier.

    BURGTEC THICK-THIN RACE FACE CINC DIRECT MOUNT CHAINRING MAIN FEATURES:

    • All Burgtec chainrings are +/- 2 teeth so: 30T Has a combination of 32T increased power phase and 28T dead center. 32T Has a combination of 34T increased power phase and 30T dead center.
    • To choose the right crown, stick to the one currently mounted.
    • Thick and thin tooth profile with Mud Bleed.
    • 10 11 and 12 speed compatible.
    • 115 degrees of ovality.
    • Fully CNC machined from 7075 aluminum.
