CORONA BURGTEC THICK-THIN RACE FACE CINC DIRECT MOUNT
The CORONA BURGTEC THICK-THIN RACE FACE CINC DIRECT MOUNT offers the mechanical advantage of increased transmission. Through numerous prototype tests with varying degrees of ovality, it has been found that 115% (from the center upward) is optimal. This appropriately reduced the dead spot and provided the same perfect chain retention and quiet operation of round sprockets. Shortening the dead spot at the top and bottom of the power curve allows returning sooner to the power phase of pedal rotation.
CORONA BURGTEC THICK-THIN RACE FACE CINC DIRECT MOUNT MAIN FEATURES:
- All Burgtec sprockets are +/- 2 teeth, therefore: 30T has a combination of increased power phase with 32T and dead spot of 28T. 32T has a combination of increased power phase with 34T and dead spot of 30T.
- To choose the right sprocket, refer to the currently mounted one.
- Thick and thin tooth profile with Mud Bleed.
- 10, 11, and 12-speed compatible.
- 115 degrees of ovality.
- Fully CNC machined from 7075 aluminum.
