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 test of different prototypes with variable amounts of ovality it was found that 115% (from the center alto) is optimal. This has adequately reduced the dead spot and provided the same perfect chain retention and quietness as round corone. The shortening of the dead spot at the top and bottom of the power curve allows you to return prima to the power phase of the crank rotation.
CORONA BURGTEC THICK-THIN RACE FACE CINC DIRECT MOUNT KEY FEATURES:
- All Burgtec corone are +/- 2 teeth, therefore: 30T has a combination of increased power phase 32T and dead spot 28T. 32T has a combination of increased power phase 34T and dead spot 30T.
- To choose the right corona, stick to the one currently installed.
- Thick and thin tooth profile with Mud Bleed.
- 10, 11 and 12 speed compatible.
- 115 degrees of ovality.
- Fully CNC machined in 7075 aluminum.
