CORONA OVALE BURGTEC OVAL THICK-THIN GXP BOOST 3 MM OFFSET
The CORONA OVALE BURGTEC OVAL THICK-THIN GXP BOOST 3 MM OFFSET offers the mechanical advantage of greater transmission. Through numerous tests of different prototypes with varying amounts of ovality, it was found that 115% (from the center at the top) is optimal. This has adequately reduced the dead spot and has given the same perfect chain retention and quietness as round chainrings. Shortening the dead spot at the top and bottom of the power curve allows you to return sooner to the power phase of the crank rotation.
MAIN FEATURES OF CORONA OVALE BURGTEC OVAL THICK-THIN GXP BOOST 3 MM OFFSET:
- All Burgtec chainrings are +/- 2 teeth, therefore: 30T has a combination of an increased power phase of 32T and a dead spot of 28T. 32T has a combination of an increased power phase of 34T and a dead spot of 30T.
To choose the right corona, stick to the one currently mounted. - Thick and thin tooth profile with Mud Bleed.
- Compatible with 10, 11 and 12 speeds.
- 115 degrees of ovality.
- Fully CNC machined from 7075 aluminum.
